Heap memory allocation

Selvam_Sekar — Tue, 23 May 2023 12:27:00 GMT

Hi,

I am trying to find the process groups max allocated memory in the Dynatrace. I used this metric "JVM runtime total memory" metric but the value is mismatching.

For example,

in the code, the memory allocated for the process group is 512 MB where as in Dynatrace could see only 490 MB.

JVM config in MB:

DataExplorer in MiB:

I hope it helps.
