Hi all,
I have rate()[1m] not return data issue at some datapoints. And I am trying to understand it.
In my system, the scrape_interval is 15s and my query looks like: rate(grpc_server_requests_seconds_count{namespace=~“$namespace”, release=~“$release”, app=“nlu-orchestrator”, statusCode=“OK”}[1m]), a few data will be missing as shown below. if I remove rate()[1m] and rerun the query, I could get all datapoints with grpc_server_requests_seconds_count.
I put raw data side by side for the same release, same container as below. As you can see, at the time at 2:56:30, the one with rate()[1m] don’t have value continuously for 4 times. However, on the left side without rate(), there are values. These 4 values in green should be used for calculate the 1st red entry at 2:56:30 with rate()[1m], but we got an empty cell.
The rate() calculation is still a mystery for me. If anyone could give me an example how it was calculated exactly, that would be really helpful! Thanks a lot!
