CPU Usage - Chart - Dashboard

Thi is the Dynatrace dashboard, custom chart page. Trying to create CPU usage chart - Maximum (5 mins window) and it shows 95% CPU utilizaton for some of the hosts.

When I click on the individual host, it is showing way less value

 

I would like to understand the aggregation method used in the individual host page.

 

Also, if VM has 4 cores, the CPU percentage provided by Dynatrace is the aggregation of all 4 cores, is it?

I tried to replicate your data, but it's good, as it should be. What OS are your hosts running (suppose it's Linux)?

And yes, the CPU percentage considers all the cores in a VM.

Could you filter the custom graph to include only the host you are showing below?

Sharing the custom graph as requested


Looks like around 08:47 the CPU value that was seen in the first graph is similar to the custom graph. But the 08:51 value is nowhere near 100% in the first graph as it is in the Custom Graph.

I would suggest opening a support ticket, so someone can look at the values more clearly.

So the host page you are showing is Linux. The system adds up all of those metrics to give you the overall usage. This is the percentage of usage for all the cpus allocated for that host (1,2,3,4 and so on)
