query concern

[vinhnguyen-ct]

hi All,
I saw that we use error_query and total_query with: sum(rate) function in the template.

My concern that is it right function to use by that I check around that there is another function: sum(increase) is better than to use for count number of request error in a windows time instead calculate the average error rate.

Current: it may calculate a average number of error request and total request in a window time.
error_query: sum(rate(http_request_duration_seconds_count{job="myservice",code=~"(5..|429)"}[{{.window}}]))
total_query: sum(rate(http_request_duration_seconds_count{job="myservice"}[{{.window}}]))

Expect: it's count the number of error request and total request in a windows time.
error_query: sum(increase(http_request_duration_seconds_count{job="myservice",code=~"(5..|429)"}[{{.window}}]))
total_query: sum(increase(http_request_duration_seconds_count{job="myservice"}[{{.window}}]))

Am i correct ? look for idea about this to have a good result about error budget to tracking svc.

Thanks before hand
