rate¶

Description¶

Calculate the average per-second rate of the argument across the group.

rate by default assumes the value to be monotonically increasing, and treats decreasing values as counter resets.

When the argument is a metric defined using set_metric, rate behaves differently according to the specified metric type:

for gauge and cumulativeCounter metrics, rate will retain the default behavior of assuming monotonic increases.
for delta metrics, rate will sum up the values and then divide by the frame size to calculate average per-second rate.

float or duration

This is an aggregate function (aggregates rows over a group in aggregate verbs.)

This is a window function (calculates over a group of multiple input rows using windowing.)

rate(value)

Argument	Type	Optional	Repeatable	Restrictions
value	numeric or duration	no	no	none

align 5m, requests: rate(m("requests_total"))

Computes the per-second rate of “requests_total” metric for each 5m time bins. The rate is always positive, and resets if the counter goes down.
