I am not able to see purepaths.If performance warehouse is not connected,we cannot see purepaths.If so when connecting to the performance warehouse I am getting the error.
FATAL: could not write init file
This is quite odd. PurePaths are not stored in the Performance Warehouse and should be available whatever the connection status to the DB is.
I recommend you to open a support ticket, with a support archive.
I also agree with Nicolas. Not seeing PurePaths is not related to the connectivity of your Performance Warehouse. If you do not see PurePaths I would check
a) is your dynatrace agent correctly connected
b) do you have any load on your application so that dynatrace can pick up PurePaths
c) if it is a non-web application make sure that you have Entry Points defined so that dynatrace can capture PurePaths
d) make sure you have a valid license
In one of my engagements, I had seen that the "Capture Events" was unchecked and once we checked that, we were able to capture the Purepath again. Sounds a silly mistake, but still you can have a look on that 🙂
System Profile-> Agent Group -> Agent Mapping
on a similar note, it is worth checking the uem screen via the profile to make sure that purepaths are captured. There is a slider (on each application tab). Make sure it isn't on the left hand side but in the middle or right.
Thansk florent.It works now,It was set to extreme left before ,now we changed it to middle and run the transactions it was showing all the pure paths.why it will not show if it set to extreme left?
One that I have seen is that the disk where sessions are to be stored is (almost full). Dynatrace will never fill up a disk completely so if there is not enough space available no PP will be written.
You can try to show the "in flight" PurePaths on the PurePath dashlet (the icon in the top right with the "gears").
If PurePaths show up there but get deleted afterwards you might be suffering from above problem.
Changing the session store location or freeing up disk space should solve it.
