Figuring out high cpu usage queries in prometheus
I am in charge of managing a prometheus cluster for multiple teams. Average CPU utilization is 0.6 of 4 allocated CPU cores. However sometimes prometheus is maxing out the CPu at 4 cores for severel mintues or sometimes even hours.
I assume the high CPU usage is being caused by Grafana dashboards which run a lot of (inefficient) queries. Since each time has several grafana dashboards I am having a hard time figuring out what dashboard or even query is causing the high CPU usage on my prometheus cluster. The even bigger problem is, that this causes all other dashboards to be very slow because the prometheus instance can not answer queries in a timely manner.
The question
How could I figure out what queries are consuming a lot of CPU usage or how could I limit the CPU usage for queries / teams?
