PurePaths older than two days not visible any longer

Hi

PurePaths are not stored in the Performance Warehouse but in the session storage on the file system.

There are two reasons I can think off

a) you are not using Continuous Session Storage - which allows dynaTrace to save all PurePaths automatically on disk

b) you are running out of Disk Space used by the Continuous Session Storage. In that case older PurePaths are automatically deleted

Have a look at the Settings tab in the Server Settings dialog. There you can see how much storage space you have configured and how much is actually available.

What I've also seen in the past is that customers end up withi a lot of stored sessions that also take away storage space from our continuous session storage. Open your Session Browser and see whether you have a lot of stored sessions that you may no longer need and delete them - or - if you still need them you can export them and store them somewhere else

Hello and thanks for the reply.

I had misunderstood the concept of the performance warehouse. I understand now that PurePaths are not at all stored in there but in RAM or on disk depending on the setting you mentioned.

You were absolutely right we were not using Continuous Session Storage but we have enabled it now. Unfortunately the data is lost since we did not have this setting enabled but it was a valuable lessons learned for the future.

Sorry for learning these lessons "the hard way"

Continuous Session Storage is on by default for several dynaTrace releases now. Maybe you unchecked it by accident?

Anyway - good to know that we solved that mistery

Mikael, is this in your test system? Since I believe there is people using the REST API there for test purposes where they might very well turn continuous session storage on and off can you check with your colleagues. I know Björn did some work around that (but he might be on paternal leave).
