I have installed a PLM peer and created a PLM test but no data reported in the test. How to troubleshoot?
I can see the peer listed on the View Network Machine Profiles page (under Measurement Locations > Private Last Mile) but my PLM test has no data.
Dynatrace Synthetic Classic > Private Last Mile (PLM)
If you see "Last Check in Time" for the Peer Population is "never" whereas the "Last Check in Time" for the peer is up to current, it implies that the Peer is not included in the Peer Population. Please edit and update the Peer Population, delete the current instant test and run a new instant test to test again. (Check here for how to configure a Peer Population.)
If the peers are checking in fine and those peers are correctly included in the peer population ( peer population criteria are correct), there are two other possibilities.
1. The peer population has wrong status for the assigned tests. Peer Population needs to have status as Active under MBGPopulation table of PLM DB. If the status of the peer population is wrong, no tests will run from it.
2. The peer(s) are not correctly synchronized into the PLM job queue servers: plmjq02 or plmjq03/04. (Server name: GLMDC2jq02.gomez.com or GLMDC2jq03.gomez.com).
>>Double check the PopulationDefinitions table in PLM DB to see if the peer(s) are included in the population's definition. Example of sql query is as below:
select * from PopulationDefinitions (nolock)
where Value in ( 'peer's usys_id')--//find population by peer id
>> Connect to jq02 server and check if you can find the peer(s) under the JobQueueLookup table.
If you have confirmed the issue, this needs to be fixed by Dev and DBAs. Open Support ticket.
