Cannot increase dynatrace client memory above 14336MB.

Due to this, post processing is failing and error is 'Not enough memory to calculate all garbage collection sizes'. (Sufficient RAM and disk space is available)

Hello @Siddhi B.

Do you really need more than 14 GB memory for the client?

The AppMon Memory Analysis Server (formerly Analysis Server) is used solely for post-processing memory snapshots.

Have a look on the below link for configure memory on memory analysis server.

https://www.dynatrace.com/support/doc/appmon/installation/install-memory-analysis-server/

Memory dump size is 13GB. I made changes in 'dtanalysisserver.ini' still facing same issue


Hello @Siddhi B.

Change the memory settings as mentioned below and make sure both sizes are same and restart the service.

This is to analyze the 13GB dump size but if you have enough memory then you can go beyond this value.

-Xmx3328M
-Xms3328M

Yes we require more than 14 GB for client. Could you please guide how to increase it?

We have imported a memory dump with offline session monitoring.


Hello @Siddhi B.

If you are using Rich Client follow the instructions.

To change the used memory for the AppMon Client, choose Settings > Dynatrace Client and set the Maximum heap memory to a reasonable size.

Yes tried the same and also made configuration changes in dtanalysisserver.ini but still we can't increase maximum heap memory beyond 14 GB.
