Label replace over a range vector in Prometheus

阅读更多关于 Label replace over a range vector in Prometheus

问题 I want to find the sum number of alerts for all the pods starting with "sendsms" over 10minutes. I am able to do use label_replace() to do this on the instant vector.

Explaining the problem with an example: ALERTS{alertname="CPUThrottlingHigh",pod="sendsms-dbed"} 10 ALERTS{alertname="CPUThrottlingHigh",pod="sendsms-ebed"} 20 ALERTS{alertname="CPUThrottlingHigh",pod="sendsms-fbed"

(I realize that the metric cardinality needs to be improved, and I've updated the app to fix it. However it left me with this

In other words, If I select 24hs I'd like to use that data in the query. 回答1: There are two ways that I know: You can use the $__interval variable like this: increase(http_requests_total[$__interval]) There is a drawback that the $__interval variable's value is

There are two ways that I know: You can use the $__interval variable like this: increase(http_requests_total[$__interval]) There is a drawback that the $__interval variable's value is adjusted by resolution of the graph, but this may also be helpful in some situations. This approach should fit
