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(requests[3 sec])) ON(foo)

Query functions | Prometheus
https://prometheus.io/docs/prometheus/latest/querying/functions
rate(http_requests_total{job="api-server"}[5m]) rate should only be used with counters. It is best suited for alerting, and for graphing of slow-moving counters. Note that when combining rate() with an aggregation operator (e.g. sum()) or a function aggregating over time (any function ending in _over_time), always take a rate() first, then aggregate.

09.05.2016 · The individual rates would be: rate(http_requests_total{job="node"}[5m]) Now to aggregate those, you'd do: sum by (job)(rate(http_requests_total{job="node"}[5m])) # This is okay. Seems simple, right? How not to do it. A common mistake is to try to take the sum and then the rate: rate(sum by (job)(http_requests_total{job="node"})[5m]) # Don't do this

Assuming that the http_requests_total time series all have the labels job (fanout by job name) and instance (fanout by instance of the job), we might want to sum over the rate of all instances, so we get fewer output time series, but still preserve the job dimension: sum by (job) ( rate (http_requests_total [5m]) )

Prometheus Metrics: A Practical Guide – Tigera

To tell if the CPU has been busy or idle recently, use the rate function to calculate the growth rate of the counter: (sum by (cpu)(rate(node_cpu_seconds_total{mode!="idle"}[5m]))*100. The above query produces the rate of increase over the last five minutes, which lets you see how much computing power the CPU is using.

07.10.2018 · Otherwise rate() cannot detect counter resets when your target restarts. If you can tolerate this (or the instances reset counters at the same time), there's a way to work around. Define a recording rule as. record: job:mycounter:sum expr: sum without(instance) (mycounter) and then this expression works: sum(rate(job:mycounter:sum[5m]))

Breaks in monotonicity (such as counter resets due to target restarts) are automatically adjusted for. So, taking only the last two data from our serie We applied the formula
