Azure file sync - When running FileSyncErrorsReport.ps1 I only get information on one sync group, not all of them

Question

Azure file sync - When running FileSyncErrorsReport.ps1 I only get information on one sync group, not all of them. How can I get output on all the sync groups registred on a server??

@Kim K Hansen

If the FileSyncErrorsReport.ps1 script returns "There were no file errors found" or does not list per-item errors for the sync group, the cause is either:

Cause 1: The last completed sync session did not have per-item errors. The portal should be updated soon to show 0 Files Not Syncing.

Check the Event ID 9102 in the Telemetry event log to confirm the PerItemErrorCount is 0.
Cause 2: The ItemResults event log on the server wrapped due to too many per-item errors and the event log no longer contains errors for this sync group.

To prevent this issue, increase the ItemResults event log size. The ItemResults event log can be found under "Applications and Services Logs\Microsoft\FileSync\Agent" in Event Viewer.

@Kim K Hansen Adding more info to the deherman response. Adding PS1 is run on the ServerEndpoint and by default it will return info on all sync groups (in which this Server is participating). If this server is not part of the sync group, then it may not return info Check the PS1 code to understand more info, Therefore it may not produce data for sync group the server is not part of it

Here is an example when running FileSyncErrorsReport.ps1 it reports "There were no file errors found. Done" The telemetry log shows UploadPerssistentErrors 18

and the 18 count is persistent with what Azure dasboard reports:
