Hey, I am trying to read the Atlas Metrics for CPU but i am confused a bit. So the metrics page has two CPU metrics.
- Normalized System CPU
- Normalized Process CPU
Normalized System CPU
For my cluster, the user value is well under 40% on all nodes. Primary and Secondaries. For the last 30 days
Normalized Process CPU
Now this one show two values.
- User: This one is 30-40% for the last 30 days.
- Max User: This one has gone upto the 80s as well.
Now i was thinking about using a Lower CPU cluster but i am sure which metric or value that decision would depend on. Now i know the cluster depends on other factors like RAM, etc. But for now i just want to understand this. Which metric and which value inside the metric should i look at if i want to how much CPU is being used by cluster, Or how much average CPU my cluster and system require to work
