25.03.2019 · If we divide these we get the average duration of one observation: rate (prometheus_rule_evaluation_duration_seconds_sum [5m] / rate (prometheus_rule_evaluation_duration_seconds_count [5m]) One thing to be aware of is that if there's no observations in a time period, then this would return NaN. This makes sense as …

25.11.2020 · The sum function will sum the values of the different rates; and sum (rate (requests [3 sec])) will give you only one value: {} 42.13 <-- the sum of all rate (requests [3s]) values. BONUS: In the case you metric have multiple dimensions (represented by multiple labels in your metric) you can tell sum () to operate on a subset of them: sum (rate ...

May 09, 2016 · Rate then sum, never sum then rate There's a common misunderstanding when dealing with Prometheus counters, and that is how to apply aggregation and other operations when using the rate and other counter-only functions. Aggregation is core functionality of Prometheus, and it's most commonly applied to counters.

The sum function will sum the values of the different rates; and sum(rate(requests[3 sec])) will give you only one value:

To be exact, Prometheus only stores floating-point values with double precision. The rate function takes metric and time information enclosed in [braces] as a ...

rate(v range-vector) calculates the per-second average rate of ... Note that when combining rate() with an aggregation operator (e.g. sum() ) ...

Nov 25, 2020 · The sum function will sum the values of the different rates; and sum(rate(requests[3 sec])) will give you only one value: {} 42.13 <-- the sum of all rate(requests[3s]) values BONUS: In the case you metric have multiple dimensions (represented by multiple labels in your metric) you can tell sum() to operate on a subset of them: sum(rate(requests[3 sec])) ON(foo)

condition where rates turn to be all zero for counters that change their value on a whole minute boundary. But don't take my word on it — let's ...

PromQL is a built in query-language made for Prometheus. ... sum-rate. This query tells you how many total HTTP requests there are, but isn't directly ...

For Prometheus: the rate of the stable pods is constant, so 15R. The short lived pods rate is calculated over the entire range vector, so 1000R ...

There's a common misunderstanding when dealing with Prometheus counters, ... A common mistake is to try to take the sum and then the rate:

Mar 25, 2019 · This isn't much use on its own, but we can use rate() as we would with other counters. rate(prometheus_rule_evaluation_duration_seconds_count[5m]) is the number of observations per second over the last five minutes on average, and rate(prometheus_rule_evaluation_duration_seconds_sum[5m]) is how long they took per second on average. If we divide these we get the average duration of one observation:

Prometheus is an open-source tool for collecting metrics and sending alerts. It was developed by SoundCloud. It has the following primary components: The core Prometheus app – This is responsible for scraping and storing metrics in an internal time series database, or sending data to a remote storage backend.

07.10.2018 · I have a Prometheus counter, for which I want to get its rate on a time range (the real target is to sum the rate, and sometimes use histogram_quantile on that for histogram metric). However, I've got multiple machines running that kind of job, each one sets its own instance label. This causes different inc operations on this counter in different machines to …

19.07.2021 · Prometheus makes available great functions for data aggregation by timeline. Among these functions, I focused my analysis on irate() and rate() which give us similar outcomes but they work in different way. Let's see, by making an example, what happens under the hood to understand how it works. Prometheus is a very powerfull data collector…

Learn how to use Prometheus's rate() function. See two example use cases for rate() used for alerting and for SLO calculation.

Return the 5-minute rate of the http_requests_total metric for the past 30 minutes, with a resolution of 1 minute. rate (http_requests_total [5m]) [30m:1m] This is an example of a nested subquery. The subquery for the deriv function uses the default resolution. Note that using subqueries unnecessarily is unwise.
