Binary Operators

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 create different …

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.

That means, for each instant t in the provided instant vector the rate function uses the values from t - 5m to t to calculate its average value.

Prometheus 2.0 introduced the group() operator for exactly this purpose. ... we use the following query which uses PromQL's rate function:.

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.

Use the rate() function to specify the time window for the quantile calculation. ... Capturing groups in the regular expression can be referenced with $1, $2, ... This function was added in Prometheus 2.0. vector() vector(s scalar) returns the scalar s as a vector with no labels.
