Skipped PurePath on a single agent installation
Hi All,
we have a customer who have sent us the attached screenshot after connecting only 1 dt 4.2 agent. As you can see it shows a lot of unrecorded purepaths. Any ideas whythis should happen ? is it the buffer size ?
Gil.
I suggest you open a support ticket, but in the meantime looking at the logs may be helpful for you to identify the issue.
At the customer I was at the main reason for skipped PP was too many purepaths with over 600 000 milisseconds of duration and purepaths with over 100 000 nodes (due to thousands of exceptions we should not even capture at the first place).
On your screenshot we don't see the Purepath Max Duration, the length looks fine but I would look at that metric while opening the support case. Definetely open the case tho because there could be other reasons.
Gil,
Unrecorded PurePaths are those that are not written to the disk using continuous session storage. Can you check if that option is enabled and if the server is able to write to the disk/folder that is configured?

PS: I would also suggest to upgrade to 5.5...
Roman,
Despite recommendations the customer is working w/o continous storage. if they are not recorded what would be the side affect ?
Without continuous storage the PurePath data will be lost as soon as it has to be removed from the in-memory buffer. So much shorter data retention...
Best, Roman
based on what i can recognize on your screenshot, it seems there is not much load on this system:
MPS (Nodes per Second): ~1000
PurePath Length: ~3000
PurePath Buffer: ~80000
whis would mean in average every 3 seconds there's a new PurePath (which is basically nothing) and with a PurePath Buffer of 80000 this would mean an in-memory data retention of about 66 hours.
though this is kind of a high in-memory data retention, it is still strongly recommended to turn on continuous session storage!
best,
Christian
