I believe dynatrace shouldn't occupy more than the specified storage limit in the Storage Settings. But, when i got to the server and check the Size on the server, i can see that the dynatrace installation folder is way more than the storage limit (818GB on disk and storage quota is 680 GB). Please refer the screenshots attached.
Is there anything I am missing here? Is it expected?
I would check the directory stored \sessions where you have it set in the dynaTrace server and see what is in there if anything other than dynaTrace session data. You can also have Memory, Thread and CPU dumps you have taken stored in the directory as well.
You can double click on Session(in cockpit) and see what is taking up the space You can also go into debug mode and see what session data is live and actively recording?
Continuous Session storage mechanism always writes chunks of 5GB files to the session directory. If you reduce the session quota size the oldest 5GB will be deleted. The session management mechanism should be overwriting older data to stay within the specified quota.
I have cross checked and can see only session, memdump, threaddump and sampling data under sessions\stored\<my system profile>
I dont have any new session storage or memory dump/ thread dump / CPU sampling running or created in the recent past. I used to have 750 GB out of 836 GB as the storage quota and i had reduced it to 680 GB after my disk was full. I dont want to reduce the quota further, as I will have lesser historical purepaths.
your second screenshot confirms what Jerry was referring to: lots of Memdumps and exportet sessions. The session quota that you have set only counts for the continous session storage and not for manual created sessions, which you have to remove manually.
