Prometheus query timestamp. Metrics are not shown in Prometheus query browser.

Prometheus query timestamp NOTE: there is no way to associate historical values with timestamps in the the past with this exporter! So, the results of queries run by prometheus-bigquery-exporter should represent a meaningful value at a fixed Timestamp: Fixes a query single moment in time of your choosing. The queue time is part of the two-minute default timeout. duration are values to protect Trino from too much data coming back from Prometheus. Use the timestamp() function to align time series before joining. I know of the following queries: 1. sum_over_time: Similar to the first query, but here it aggregates data for smaller 15-second intervals. If you need higher precision for the returned The Prometheus monitoring system and time series database. It forms the backbone of extracting insights from your metrics data. E. Panel : Stats Expected Output : Time Threads 2023-05-12 03:00:00 2789 I have framed the below query, but it is showing the current timestamp timestamp(max_over_time(mysql_global_status_threads PromQL Service PromQL(Prometheus Query Language) Service exposes Prometheus Querying HTTP APIs including the bundled PromQL expression system. The graph view has always supported adjusting the end time of the graph, in the timestamp(changes(up{job="prometheus"}[1h]) > 0) * 1000 But I cannot figure out how to get the timestamp at which my metric last changed it’s value. None of these seem to solve the problem. Range vector: What Prometheus query (PromQl) can be used to identify the last local peak value in the last X minutes in a graph? A local peak is a point that is larger than its previous and next datapoint. time When I use the Prometheus GUI to query directly, I am not sure of the syntax of putting the date time range. Self-Paced Courses Live Trainings. Add a Comment. last_over_time() rollup function, which returns the last value per each time series on the given lookbehind window d in square brackets. Assume we are going to create a metric my_metric that The example given is using a writer as I don't know how to add a timestamp with the library. Collectors When implementing a non-trivial custom metrics collector, it is advised to export a gauge for how long the collection took in seconds and another for the number This isn't possible, label values are opaque strings to Prometheus. Load 7 more related questions Show fewer related questions Sorted by: Reset to Hi, I am looking for a query to calculate the wait time between two metrics. The query language allows filtering and aggregation based on these dimensions How to query the latest value per timeserie in MetricsQL or PromQL? For example, query metric_name returns two timeseries for metric_name{job="foo"} and metric_name{job="bar"} f Skip to main content Prometheus metrics with timestamp. --end: Query range end time (RFC3339 or Unix timestamp). Note that node_load1{instance="host1",instance="host2",instance="host3"} won't return any results, since the label filters are applied with and operation, e. The following endpoint evaluates an instant query at a Prometheus uses a simple model based on labels, values, and timestamps — the labels collectively form a series with multiple samples. In Prometheus v2. Follow In PromQL, such time parameters are sent separately from the expression to the Prometheus query API, and the exact time parameters depend on the type of query you are sending. How can I query prometheus for the last value over a specific range (i. start=1727625600: The start timestamp for the query range (start of the day). Do note that the characters in the The Prometheus Query Language (PromQL) is a powerful and flexible language used to query and manipulate time-series metrics in Prometheus. Improve this answer. If you can get the data exposed as a unix timestamp then you can use the max aggregator to get the highest value. For example, the following MetricsQL query returns the timestamp in seconds for the maximum value of site_logged_in metric over the last year: tmax_over_time(site_logged_in[1y]) Which in turn enables writing queries like: sum_over_time( ( tracking_error:absolute * ignoring (endpoint,instance,job,namespace,pod,service) group_left (errorName) (tracking_error:timestamp:labelled-(tracking_error:timestamp:labelled offset 1m)) )[1m:] ) It feels very icky. Prometheus expression query string. So let’s say I have a metric called “temp” which is temperature in celsius. Hi, does anyone know if it is possible to use a Prometheus metric value that happens to be a timestamp as the timestamp when that metric is graphed in Grafana? Our metric returns a value such as 1690396973. This is the case for both instant queries and range queries. This endpoint allows you to run PromQL queries against the Prometheus database Hello community, I have a counter metrics say api_msg_count which keeps on increasing based on incoming no. Flag Description Default--server: Prometheus server to query. If a pod is still running, the time from its creation to now First one gives values but the timestamp is not the actual time of the event.

Specifically, The Prometheus time value corresponds to the TIMESTAMP field. And when the value is equal to 0 for 1 hours, it will return 6 time intervals. The prometheus. However, GreptimeDB supports storing high-precision timestamps I'm trying to show system uptime as DD-HH-MM-SS format, doing it using common code wouldn't be an issue but I'm doing it using Prometheus (PromQL) and Grafana only, here's the PromQL query: time()-process_start_time_seconds{instance="INSTANCE",job="JOB"} I achieved the basic output I wanted, it shows me the process life time. The start and end timestamp, the step and the actual query statement. It provides the following gauge: # HELP process_start_time_seconds Start time of the process since unix epoch in seconds. Discover techniques, best practices, and real-world examples for effective metric correlation. To disable the query log, The query. You can similarly split them per month and then use the Grafana reduce "series to rows" transform to calculate the total per month. If there are 3 machines, there are 3 separate tags, for machine1, machine2, machine3. abs(v instant-vector)returns the input vector with all sample values converted totheir absolute value. However, new experimental features were added to Prometheus where the Protobuf format was considered the most viable option. docs Here is an example of a query I am trying to plot on grafana: topk(5, sum by (service) query=<string>: Prometheus expression query string. e. The content of the chunks is basically a set of metadata, which is mainly composed of a first field containing the number of chunks containing data for the current series and then, for each chunk, we have the minimum timestamp in the chunk for the current time series and the maximum timestamp for the current time series. I already have a connector that exports metrics stored in MLFlow and makes them visible to prometheus. December Prometheus will run them all with the same query evaluation timestamp. How can I run the following query but return an int instead of a forma You can compare metric value with result of function time(). docs Here is an example of a query I am trying to plot on grafana: topk(5, sum by (service) What happened: In a query to Prometheus that returns only a straight metric, I have two labels that include timestamps. However, GreptimeDB supports storing high-precision timestamps I'm a prometheus newbie and have been trying to figure out the right query to get the last continuous uptime for my service. Which PromQL function do I use to find the highest and lowest response time (also transformations mostly) I've noticed the queries behave differently in general when being run over grafana versus being run over the prometheus dashboard. What is the pre-existing timestamp and how / where does it come from? Query language expressions may be evaluated at a single instant or over a range of time. Provide unix timestamp. I either get query I’m trying to find the timestamp for the maximum or minimum reading. Each time series within an instant vector contains a single value corresponding to the specified timestamp. However, this will give you the right data with wrong (or confusing, because time offset is not applied to) timestamp. Each sample is a pair of timestamp and value. 1: 1756: June 7, 2023 How The file /prometheus/query. I can now query these metrics on prometheus but they are all showed at the current query time. Since value of your metric appears to contain timestamp in milliseconds (against OpenMetrics recommendations) you should divide it by 1000 to convert to seconds. This @ modifier lets you fix the ranking for all the steps in a range query. General rule of thumb: if you want to apply some operations to the label itself, other than string modification, you are doing it wrong. That's the specific of /query endpoint - it executes an instant query at current timestamp and returns the closest result. When you send a query When I run this curl command containing the PromQL query: curl -s -G "http://10. 3346083 What did you expect to see?

I would like to be able to run an instant query that would output Not exhausting your Trino available heap#. Prometheus provides two endpoints for querying: /api/v1/query aka instant query. prometheus; promql; cadvisor; Share. Get timestamp stored in DB from Prometheus query. 1 : This was also available since 2. @ÖmerSezer every unique label set results in separated time series inside Prometheus. Bug Report What did you do? I sent a query at timestamp 1567092749. We can convert this into a time value by changing the unit to date/time, however I am unable to see a way to use this returned value as the primary Querying basics | Prometheus. If the preceding examples are ingested with the same timestamp, one of them is randomly dropped. size. Arguments. Your Prometheus Query looks ok, but the curl command seems incorrect. 时间戳（Timestamp） 样本会记 Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time. Trino splits are generated by dividing the query range into attempted equal chunks. Flags. If I make a range query into the recent past where the stale metrics didn't exist Saved searches Use saved searches to filter your results more quickly Timestamp: Fixes a query single moment in time of your choosing. The query language allows filtering and aggregation based on these dimensions Hi All, Good day I would like to retrieve the timestamp of the highest value for a specific metric over a period of time using a Prometheus query. For example, to create a graph for read_latency, the results contain many tags. type EngineOpts struct { Logger *slog. set_timestamp: false #Added set_timestamp false metrics: aws_namespace: AWS/ELB aws_metric_name: HealthyHostCount Any ideas on why this resultset might be coming back as empty? I've tried getting an average by wrapping the query in "avg()" but it also gives back an empty result. BTW, from source code of prometheus, even if you do not specify a timestamp in query request, prometheus will generate a timestamp. Understanding Duplicate Samples and Out-of-order Timestamp Errors in Prometheus. If you try to display the timestamp value in the metric itself, it’s better to have a stat type panel, and then you can display the timestamp itself as last seen value. For example: Prometheus collects and stores its metrics as time series data, i. And the timestamps' frequency is set by the scrape_interval parameter in Prometheus config as far as I understand. Each key–value pair is termed It is a good practice in Prometheus ecosystem to expose additional labels, which can be joined to multiple metrics, via a separate info-like metric as explained in this article. Then you can check that and filter using and. yml file. If a label name or value changes in a To associate a custom timestamp with a Prometheus metric: Write a custom collector - you can't use the built-in Gauge class in the Python client. ReadHints hints = 4; } Explore the intricacies of PromQL, the powerful query language for Prometheus. 1, kube-state-metrics v2. It's important to note that the timestamp() function should only be used directly with a metric selector, such as up{instance="130. Such a request, when executed in the default Prometheus browser, would yield a graph dating back to Prometheus offers four core metric types to capture diverse system behaviors: Counters for tracking ever-increasing values, like the total number of exceptions thrown. its support for multi-dimensional data collection and querying is a particular strength. I know it is in Unix Epoch time. sskrlj sskrlj. @ modifier for executing the query at the given timestamp t. See The expression means I should set a large time range, which will lead Prometheus to calc the increasement of every time value to 0 (the counter is zero when it was not exposed ever) If I want to calc the increase from a specific time, I just need to minus the increase result at a You can't do it (neither sorting, nor alert): Prometheus is not equipped to deal with values in the labels. duration is the item of particular interest. As documented in 'promtool query instant --help', --time takes either a Unix timestamp or a RFC 3339 time string. 4 Store a timestamp with Prometheus metrics. As http_requests_total contains the number of requests made since the last counter restart, we see 98 successful requests. I have a java application which uses the Prometheus library in order to collect metrics during execution. Promtool will put on the rest of the URL components as needed. What are the prom queries that I can make to get these two timestamp values given the count unique label result changes? Thanks! In Grafana, I can query a DB (e. 5 Extract Prometheus Metrics in Go. In the MongoDB the collection field is Date with format (2021-08-15T18:12:02. Something like the following should provide increase of metric my_metric between timestamp and timestamp-1h : My ultimate goal is to export the data as CSV from Grafana (Inspect->Data->Download CSV), however, if there's an easier way by using the Prometheus API directly, I'm happy to do that instead. The avg_over_time function expects a range vector, which means that you could (if I understood correctly) use subquery like:. Is this even correct and is there another, better approach? Prometheus query to get the value of a metric since midnight or a dynamic offset. Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions. Instead, it returns the timestamp rounded to one minute - see 1m in square brackets above. When you make a Prometheus query in PromQL, the result has both values and timestamps for those values (as covered in the API documentation). Time-shifted data: This query, when entered in your Prometheus expression browser will result in something like the following query results: Guide on using Prometheus Query Language (PromQL) in GreptimeDB, including HTTP API compatibility, SQL extensions, and supported features and limitations. jvm_memory_usage_after_gc_percent 2. Now() result, warnings, err := v1api. 242. Every row in that table represents a series with the last available value. <STEP> identifies the query resolution step width. max. That’s because Prometheus doesn’t generate timestamp directly from the data’s timestamp, but in a reversed way, where the timestamp in the result is determined first, then finds values suited for that timestamp and feeds them into calculate operators. t := time. It should be for the last hour for each 5 mins interval. 3,837 6 6 gold badges 39 Query range start time (RFC3339 or Unix timestamp). 248. Now, I have some time series that haven't been updated anymore (i. (So I have a Kubernetes cluster with an install of kube-prometheus-stack (Prometheus 2. There's a similar way with Graph. When used in this way, it will return the I'm querying a metric's values over a period of time like metric_name[1w] which returns a metric value for every timestamp. 29 1 1 Get timestamp stored in DB from Prometheus query. The metrics are coming from prometheus and are coming in the millescond timestamp format such as this: default_jenkins_builds_last_build_start_time_milliseconds{instance=“REMOVED”, jenkins_job=“REMOVED”, job=“jenkins”, repo=“REMOVED”} Try enabling the Instant option The input parameters are similar to the range_query in Prometheus' HTTP API:. chunk. This endpoint accepts the timestamp for the query at time argument. PromLabs - We teach Prometheus-based monitoring and observability. Example: built from ubuntu container (quirky_morse, sleepy_wilson, cranky_booth) and prometheus container. As In a Prometheus timeseries database, there are two sets of data (for M1 and M2) collected with following schema <timestamp>, <M1> <Labels L1, L2, L3> <timestamp>, <M2> <Labels L1, L2, L3, L4> Write a PromQL query that creates a new time-series N, that tracks the max(M1, M2) for each time period the query is run. ; Histograms for observing the distribution of values within predefined buckets. From what I understand this is difficult but a workaround was posted in issue #8966. Prometheus doesn't provide any functions which can readily do this. 309+00:00) . The last timestamp returned in the query will be the last complete interval that falls within the queried range, in this These queries use @ modifier for fixing the end of the time range at t. 27. Although, Grafana has the first_over_time as it is shown here. Time object, get the local version of the timestamp from this object, and then run it through the go library provided . •If you have 'rate(http_requests_total[5m])', you can evaluate this at a query step(aka Resolution) of It looks like you are attempting to use the timestamp() function multiple times in a row, chaining it with various date-related functions such as year(), month(), and day_of_month(). are stale) for a long time. , $__from and $__to timestamp > sum by (job) (http_responses_total{job=“paytailapi”}) I have the above query and I need to show count on a daily basis (one selected from Grafana timepicker) but I am getting cumulative count for each Bit more about the solution. If your range vector queries are slow, consider these techniques to improve performance: Reduce the Query Time Range: Shortening the time range for your query reduces the amount of I use sub-queries to get hourly aggregated values for the last week for example: The number of http requests per hour over the whole last week, which will return 168 values in a range vector. Tool to query multiple metrics from a prometheus database through the REST API, and save them into a csv file. In this article we will show you how a Prometheus query works and what it does internally to be able to improve the performance of its queries. Most likely you need to reconsider your metrics and introduce what is currently in the label as a value. , prostgres) and show the result in table; I can also query the time series data from prometheus and show the result in table in a different query. When you're working with such times, it's common to want to display I am using Grafana and prometheus and I am trying to get the timestamp at which a given metric last had it’s value changed. 本文档提供了Prometheus从入门到实战的详细指南。首先介绍了Prometheus的安装与配置步骤，包括版本选择、下载、解压和运行。接着深入解析了Prometheus的配置文件， If I use /query, I got the timestamp of the "time" parameter (here : 1662988645) curl -X "POST" -G "http://localhost:7201/api/v1/query" -d "query=third_avenue" -d There are two Prometheus data preprocessing options: Prometheus pattern - used in normal items to query Prometheus data; Prometheus to JSON - used in normal items and for low-level For example, the following query should return the delta for vss_device_number over the last day (see [1d]): delta(vss_device_number[1d]) The query returns deltas per each For this I need to solve 2 issues here, I will ask the prometheus question here and the Grafana question in another link. query_range) endpoint for instant queries - that is also what the tabular view uses. In case you're familiar with Oracle Enterprise Manager, the query made to generate the report there is: This query uses the following PromQL features: count() aggregate function for counting the number of time series per each unique job value. For example, the following query should return raw samples for time series matching up{app="activity-api"} for the last 15 seconds ending at the given time. timestamp() timestamp(v instant-vector) returns the timestamp of each of the samples of the given vector as the number of seconds since January 1, 1970 UTC. There's range (=number of days for which you want daily stats), end timestamp (2020-10-13 23:59:59 in your case) and resolution (86400 in your case, for 24h in seconds). A smaller step size will result in a larger amount of data points being returned, each with a smaller time interval between them. If I have a Counter http_requests_total, How can I build a query to get an integer with the total I am running the query below to parse the data from Prometheus but getting "error": "cannot parse \"\" to a valid timestamp" curl -G -v --data-urlencode 'query=sum(irate(istio_requests_total{Skip to main content. Tried with “${__to📅yyyy-MM-dd HH:mm:ss}” in the Prometheus query but still no data on Grafana. , data at a I just wanted to add to the excellent answer by Alin Sînpălean. Sum the number of seconds the value has been in prometheus query language. #137. Query range start time (RFC3339 or Unix timestamp). log should now exist and all the queries will be logged to that file. I fiddled with the online Prometheus demo using one of the metrics present there. can you check if your timestamp is a number, not a string (toggle table view just above the visualization. Our developer’s guide breaks down Prometheus Query Language in an easy-to-understand way, A millisecond-precision timestamp; For example, a time series for HTTP requests might look like this: http_requests_total{status="200", method="GET"} 1234 1623456789000. timeout flag. 7. Blog. If you query it for an instant vector, you will get the raw latest value (but with a time of "now" vs. 0, the Protobuf format was marked as deprecated and Prometheus stopped ingesting samples from said exposition format. Write a custom exporter. timeout=<duration>: Evaluation timeout. Here are Grafana transform functions you will need:. Prometheus then associates the values collected with a timestamp of the time of collection. You need to use or operation for An open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach. Is there a better way to check if it's equal 0 more than 10 minutes and return the whole big interval? I'm sending the query through API /api/v1/query query=<string>: Prometheus expression query string. Learn how to efficiently query time-series data, create insightful dashboards, and set up alerts to optimize system performance and reliability in cloud-native environments Prometheus-compatible systems accept a timestamp, key-value labels, and a sample value. The ignoring clause means don't use the ifDescr label for matching (as it's only on one of the series). The current server time is used if the time parameter is omitted. In this example I want to measure and graph average lag time of events being processed, between the timestamp the event was created Hello! I have a service that returns status 1 if the application is up, or status 0 if the application is down. 0. Prometheus Query Language (PromQL) PromQL (Prometheus Query Language) is a functional query language where the key is a millisecond-precision timestamp and the value is the measured data in Float format. The sections below describe the API endpoints for each type of expression query. It sums values for the selected time series individually per each requested timestamp (aka point on the graph) via sum aggregate function. You can see the request parameters sent using the Chrome Developer Tools: to control this behavior. Prometheus query to average over time by a specific label. Prometheus collects the current status of a system as reported by an exporter. 25. Querying prometheus label values with metric values. The start of the time range - t-d - is adjusted with the d lookbehind window in square brackets. I see this issue but it have been closed. End time in the query, use timestamp or rfc3339--help: Get the basic help info; Attention: you can use start&end OR period to query data, This is possible using NewMetricWithTimestamp provided in the prometheus golang client, but for exposing it, you have to do a little code. matejzero • You can use start and stop parameters. avg_over_time(K_utilization[1h:5m]) This will look at the K_utilization metric for the last 1h at a 5m resolution, the result should contain all labels from the metric. It uses SQLAlchemy to connect to different database engines, including PostgreSQL, MySQL, Oracle and Microsoft SQL Server. select time series with node_load1 name and with instance="host1" label and with instance="host2" label and with instance="host2" label. This count is stored in a field called metrics_count and its value is calculated prior to any enrichments by Ingest Pipelines or Agent Processors, ensuring PromQL (Prometheus query language), is a functional query language that allows you to query and aggregate time series data. Each query can be run on multiple databases, and I'm struggling with converting queries from statsD syntax to prometheus. You could also aggregate the metric in the subquery by the ipaddr label with a sum When the prometheus query is executed without a time selector, it means that it is executed for the current instant/timestamp or even a particular timestamp. What you'll want to do is put the timestamp as a value in another metric that has all the same labels (and no label label on either). step=<duration | float>: Query resolution step width in duration format or float number of seconds. At first, you have to write a new promehetus collector that implements Collector interface, then you provide your logic to set the custom timestamp for your metric. See more Solution: Perform regular query and filter the timestamp value from timestamps array. I created a metric that is exposed to Grafana by Prometheus that has Epoch time of last date/time a record was processed I want to convert the timestamp to date/time (eg. range. prometheus_engine_queries; prometheus_engine_queries_concurrent_max; If prometheus_engine_queries is greater than prometheus_engine_queries_concurrent_max, it means that some queries are queued.

It has several pod metrics that reflect pods state: I’m trying to find the timestamp for the maximum or minimum reading. Prometheus is popular due to Hi, I want to display metrics based on the date range selected in the Grafana to fetch data from MongoDB. duration and prometheus. 0, but only with additional flag --enable-feature=promql-negative-offset Learn how to join two metrics in Prometheus queries using PromQL. The timestamp of each sample in an instant-vector-typed result of an instant query will always be equal to the query's evaluation timestamp. Querying | Prometheus Toggle navigation Prometheus The key metrics for a cache are total queries, hits, overall latency and then the query count, errors and latency of whatever online-serving system the cache is in front of. Create a Prometheus Query to Alert when A Value has Been Above Threshold for Interval. However, we can leverage the toTime function provided by prometheus to convert the result to a *time. Is it possible to use the increase() function without a label in PromQL? I was trying to create a Prometheus graph on Grafana, but I can't find the function calculating the average value. Defaults to and is capped by the value of the -query. Follow answered Jul 10, 2022 at 8:28. The response is a JSON output which consists of Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time. Return Value of Metric if Hasn't Changed in 30 Minutes. An open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach. Whether you're building dashboards, setting up alerts, or exploring your data through the API, PromQL provides the tools to meet diverse monitoring What I want to do is to build graphs for containers filtered by name and image. Managing prometheus limitation of pushgateway's recent scrape time. start=<rfc3339 | unix_timestamp>: Start timestamp. If configured as 2m, it means Prometheus will query data between 2022–08–25 15:46:03 and 2022–08–25 15: but this doesn't seem to work because the operator is applied with the state of the container at each timestamp not with the latest timestamp. I want to show this increase of no. vector() I want to use QuestDB as a source for prometheus metrics (using sql-exporter), reporting the last timestamp for a given table. p. The data can either be viewed as a graph, as tabled data, or in external systems such as Grafana, Zabbix and others. Duration ActiveQueryTracker QueryTracker // LookbackDelta determines the time since the last sample after which a time // series is considered stale. Labels to fields This function separate the labels in the metric to columns. series is: a time series is a data stream of values, associated by metric name and labels, each of them containing the timestamp representing the time at which the value was measured. Besides stored time series, Prometheus may generate temporary derived time series as the result of queries. 147:6443"}. I would like to alter that samples' frequency through the query, without changing the scrape interval. I was wondering if it is possible to make Grafana show a custom X axis for those metrics? The usual X axis is in local time. retention. Query most recent values for active & stale <START> specifies the query start range and <END> specifies the end time. Set Mode to Columns; Set Labels to be only the columns that are relevant so in this case it's query-exporter is a Prometheus exporter which allows collecting metrics from database queries, at specified time intervals. LabelMatcher matchers = 3; prometheus. You need another sort transform to get the rows back in order. Just use sum_over_time(x[1h]) instead and 3600 as resolution/step. where the key is a millisecond-precision timestamp and the value is the measured data in Float format. For example, if the present time is 0:01:20 my service was up at 0:00:00, went down at 0:01:01 and went up Example of query timestamp(up) * 1000 (multiplication by 1000 to convert timestamp in seconds into timestamp in milliseconds): Share. When you send a query request to Prometheus, it can be an instant Whenever Prometheus scrapes that file, it will add a timestamp to the scraped metrics. Imagine executing this same query at a timestamp where there is a >5m gap in data the timestamp Prometheus append to a sample is the time the GET sent. Try running an instant query at specific moment of time (14:00 in your case) with specified time window (1h in your case). 10:30000/api/v1/query" --data-urlencode "query=http_requests_total @ The timestamp, encoded as varbit-int, with an absolute value in the 1st sample, a delta between the 1st and 2nd sample for the 2nd sample, and a “delta of deltas” for any further samples (i. I wonder whether we have a way in one query to concatenate the jobname from @stapelberg We want to have better support for getting raw data out, but there's already a way:. Prometheus: filter Hi All, Good day I would like to retrieve the timestamp of the highest value for a specific metric over a period of time using a Prometheus query. 3346083 What did you see instead? jacksontj changed the title Prometheus' API rounds nanoseconds in parseTime Prometheus' /query endpoint returning data After requested time Aug 29 I would like Prometheus to scrape metrics every hour and display these hourly scrape events in a table in a Grafana dashboard. Argument Description Required; server: Run queries against your Prometheus to analyze the usage pattern of certain metrics. Looks like the format is wrong. formatting a timestamp field as any form of "Date" unit yields NaN In a table, formatting a timestamp field (pulled from Prometheus metric label value) as any form of "Date" unit yields NaN Jul 30, 2021. Templates have the ability to run queries against the local database, iterate over data, use conditionals, format data, etc. On a Prometheus instance that has been running for awhile and depending on data The scalar data type in Prometheus Query Language (PromQL) represents a single numeric value at a specific point in time. I’m currently looking for a query that would return the used heap-size after a full GC run occured.

This is the case for both This is the best I could come up with, where the returned metric value time is on the Y axis and the native Prometheus timestamp is on the X axis. This will result in every series having a single value for a particular I ended up using the prometheus query language itself to get the time in seconds and selected the stat as a duration in seconds (time() - singlestatquery) Prometheus will take the timestamp (a simple in), *force* me to cast it to a In this case the query will sum up these time series. I tried using topk to limit my return but it is returning more than n specified. time to 0s, so Prometheus keeps the old data until the 128 GB limit is reached. I would like to have a query to return how much time each pod was running, over last 24 hours. --step: Query step size (duration).

I’m trying to have a graph in grafana that shows the the total time the application is online at a stretch. As SkyWalking and Prometheus have fundamental differences in You can't do it (neither sorting, nor alert): Prometheus is not equipped to deal with values in the labels. Start with Prometheus Graph Console and punch in 2020-10-13 23:59:59 into the Momentfield: Moment field of Prometheus Graph Console. I’d suggest going with the boolean based metric since you can easily see historic data when it The step parameter in a Prometheus query determines the resolution of the returned data. Kubernetes itself, Heapster and metrics-server don't provide such metrics, but you can get metrics close to what you've mentioned by installing kube-state-metrics. size to 128GiB and storage. g. answered Aug 16, 2020 at 5:27. Based on information found here : get time that passed since the last inc timestamp(foo) and (foo == scalar(max_over_time(foo[2h]))) Finally we only want to get the first/lowest timestamp value over the time window, which is what the outer min_over_time with the nested subquery should do. Time-shifted data: This query, when entered in your Prometheus expression browser will result in something like the following query results: Reducing cardinality not only improves query performance but also ensures your query remains within Prometheus’s memory limits. The goal is to suggest a calculated value for the -XmxN parameter, based on the return value I am looking for. URL query parameters: query=<string>: Prometheus expression query string.

So let’s say I have a 在 Prometheus 中，"样本"（Sample）是指时间序列数据的一个基本单位，包含了某个特定时刻的一个度量值。一个样本由以下几部分组成： 1. Instant Vector: A set of time series containing a single sample for each time series, all sharing the same timestamp; The mechanism for querying Prometheus is to use the Prometheus HTTP API. Logger Reg prometheus. Let’s learn more Every row in that table represents a series with the last available value. How would I query for metrics in a specific time/date range? Offset kind of works, but really I just want to specify a specific hour in of a specific date and get the results. Your final query might be something like activation_time/1000 < time() - 60 * 24 * 60 * 60 or floor((activation_time/1000 - time()) / 24 / 60 Prometheus query to get just latest data for every day, (Max timestamp every day) Ask Question Asked 2 years, 8 months ago. Currently, it contains internal engine timers. The timestamp precision in PromQL is limited by its query syntax, only supporting calculations up to millisecond precision. Share. of messages to the api. One such example, relevant to yesterday's entry on the time when Prometheus metrics happened, is the result of the Prometheus timestamp() function. It collects and stores metrics as time-series data, recording information with a timestamp and optional key-value pairs known as labels. When enabled, it counts the total number of Prometheus metrics within each Elasticsearch document. Another way to explain is: Prometheus TSDB stores your time series data in the format of. Making Prometheus accept Protocol Buffers once again. 1 Promql: Is it possible to get total count in Query The expression above queries the time series engine for all http_requests_total occurrences that come under the apiserver job and /api/comments handler. Series, labels, values, and timestamps in Prometheus To execute the query, Prometheus will first identify which blocks should be evaluated to satisfy the query’s time range. So far I have managed to provide a different timestamp than just query time by creating a custom Gauge instance. How can I join the results from these two queries? I know if •A range query's query step(aka Resolution) is completely independent from any range durations specified in the PromQL expression it evaluates. As the samples are taken at random times, Prometheus has to PromQL, a powerful query language for Prometheus metrics; Prometheus PromQL. Hot Network Questions Ribe's Theorem: finitely representability between two uniformly homeomorphic Banach Found examples how it is used in Prometheus UI for querying min/max/avg from range, but is it somehow possible to use it in API requests with an above example endpoint to get min/max/avg value directly in JSON response? from which I request the average of the hour before the unix timestamp passed along. The value of ifDescr is always "1" so it's safe to multiply. 0. Use PromQL to query and aggregate metrics stored in an Azure Monitor workspace. The start timestamp, which is inclusive.

Query instead of v1api. This is called an instant vector, the earliest value for every series at the moment specified by the query. This is what I came up with: max by (service, PromQL - Prometheus - query value as label. [15s:1s]: Each interval spans 15 seconds with a resolution of 1 second. The evaluation timestamp is either explicitly provided via the time= HTTP parameter, or when omitted, the Prometheus server chooses its own current server time as the evaluation timestamp (see https Prometheus best practices involve efficient metric naming, label management, query optimization, storage tuning, actionable alerting, scaling via sharding, and securing access. ? message ReadRequest { repeated Query queries = 1; } message Query { int64 start_timestamp_ms = 1; int64 end_timestamp_ms = 2; repeated prometheus. I want to compare the last timestamp of a non-null value for this counter to a different ts. In this way, you are always querying "old The above query aims to get the total sum of every 1-second sample until the start of the day. Range of time: Setting a query to select over a certain period of time. Similar to how offset modifier lets you offset the evaluation of vector selector, The <timestamp> is a unix timestamp and described with a float literal. I'm not clear on this and am looking for some documentation comparing the two. This is a web server that exposes the timestamped When you make a Prometheus query in PromQL, the result has both values and timestamps for those values (as covered in the API documentation). Instant Vector: A set of time series containing a single sample for each time series, all sharing the same timestamp; SELECT time_bucket('5 minutes', timestamp) AS t, COUNT(DISTINCT a) FROM hello_info GROUP BY t See time_bucket() function description. it returns the number of distinct values for a label per each 5-minute interval by default - see staleness docs for details about 5-minute interval. For example, if the application is running for 3 hours straight, then the grafana visualization should have a “triangle” where the peak is at number 3, and Unlike with direct manual queries with curl, you don't directly supply the URL of the query API, you instead supply the top level Prometheus URL. For example, consul_service_tags metric exposes a set of tags, which can be joined to metrics via (service_name, node) labels. 73. I’m also running into this issue. He splits the data into time series per day. Prometheus metrics with timestamp. This leads to the 3rd node's data been not returned in the query. Third-party systems or visualization platforms that already support PromQL (such as Grafana), could obtain metrics through PromQL Service. of the actual sample timestamp). If a label name or value changes in a previously defined series, Prometheus will consider it an entirely new series. The serial feed is interpreted by SignalK which can read most NMEA data, then exported to a Prometheus endpoint (via a signalK plugin), Prometheus polls that endpoint every second, Grafana Polls Prometheus every second, and my dashboard refreshes every second. the query means:. From the prometheus visualizer, it seems like Prometheus scrapes around the 43 minute mark of every hour. I can get max value with max_over_time(range) function or directly in Grafana with Transformation but I don’ know how get timestamp corresponding to max value. Have you tried "tlast_over_time(m[d]) - returns timestamp for the last sample for m over d time range" to get the timestamp? See more details here. metrics information is stored with the timestamp at which it was recorded, alongside optional key-value pairs called labels. Prometheus provides a functional query language called PromQL (Prometheus Query Language) Instant vector selectors allow the selection of a set of time series and a single sample value for each at a given timestamp (instant): in the simplest form, only a metric name is specified. The interval is one of the key parameters for determining the timestamps in result. As the samples are taken at random times, Prometheus has to PromQL (Prometheus query language), is a functional query language that allows you to query and aggregate time series data. Such a design decision allows executing the same PromQL query at any timestamp or on any time range without the need to change the query itself. It has been a long-standing feature request: prometheus/prometheus/1227. I am using the following promql, which also gives me separate timestamps for the last hour divided by 5 mins. There's a query (vs. Also Prometheus doesn't push, it's all pull. 1, I have obtained a way to construct a table like you have described with prometheus metric like that. e. Debugging Query Performance Issues. I have tried using different times for the timestamp if it may be now or an hour in the past, an hour in the future or even timestamps that are associated to other data points in Prometheus. , the current timestamp is 1727675266, and it will start from now to the start of the day, which is 49666 seconds. After some experimentations in Grafana 9. ; Gauges for measuring fluctuating values, such as current CPU usage. Specifically this range syntax [5m] and rate etc. Duration // NoStepSubqueryIntervalFn is the default evaluation interval of Hey @andrekr, if you push an up based metric of boolean value, it would help you to have a cleaner graph. jvm_gc_memory_allocated_bytes_total 3. The /api/v1/query endpoint is the most commonly used endpoint in Prometheus for querying time-series data. And as @valyala said, if you install and configure VictoriaMetrics you can use it as described here. 0, we have introduced a new PromQL modifier @. all sharing the same timestamp scrape_duration_seconds{instance="localhost:9100"} But if a job fails and it's kept, even the next job succeeds, I still get an alert because there are two records in prometheus, one of which is the failure record, the other one is the success record. . yiC yiC. Prometheus knows two types of PromQL queries: instant queries and range queries. Each key–value pair is termed as Sample; i. ; Summaries for calculating quantiles The query language used in Prometheus is called PromQL (Prometheus Query Language). Prometheus is designed for reliability, to be the system I didn't find first_over_time for Prometheus. Prometheus has the following issues when calculating the increase(m[d]) at timestamp t: It ignores the increase of m between the last raw sample just before the timestamp t-d and the first raw sample on the time range (t-d t]. Improve this answer Querying prometheus label values with I need to know how to query data between two timestamps using Grafana default timepicker variable i. Is there a better way to check if it's equal 0 more than 10 minutes and return the whole big interval?
