Average & Percentile Show the Same Value for Usage Metrics? Why?

j_butzow — Thu, 24 Aug 2023 07:16:22 GMT

Hello -

I am charting CPU usage for containers, and I was hoping to display average utilization in conjunction with percentile utilization metrics on the same dashboard.

However I noticed that when I select a percentile value for aggregation, Dynatrace simply shows the me the average value twice (see screenshot). Why is this the case? Does Dynatrace not calculate percentiles for system usage metrics?

Thanks much,

Joel B

Hi @j_butzow . Not all metrics are capable of aggregate as percentile.

This one you are currently using, the builtin:containers.cpu.usageMilliCores, can be aggregated as auto, avg, max, min only.

You can check the aggregation possibilities in the metric page:

You can also find metrics that accept the percentile aggregation in the docs, https://www.dynatrace.com/support/help/observe-and-explore/metrics/built-in-metrics
