Long Queries Stops Collecting Randomly

[Drewster727]

Did you check DOCS to make sure there is no workaround?
Yes, did not see anything, unsure how to troubleshoot beyond log table and event viewer.

Describe the bug
Randomly the XES long queries will stop collecting, even though the SQL Server agent job shows no failures.
I have even manually executed dbo.usp_sqlwatch_logger_xes_long_queries which shows no issues/errors.
Additionally, I have queried the dbo.sqlwatch_logger_xes_long_queries table and it has stopped loading new records. However, other types of metrics/tables when querying those tables show they are being collected, so it appears to be just long queries.

To Reproduce
Unsure how to reproduce.
I can typically resolve the issue by right-clicking the database > tasks > delete data-tier application > confirm delete
Then I redeploy the dacpac via sqlpackage.exe and it is back working again.

Expected behavior
I expect the long queries to always collect with no intervention needed.

Additional context
I'm puzzled on how to troubleshoot this, I don't see anything glaring in the dbo.sqlwatch_app_log table nor in the event viewer.
How can I dig into the problem here? Thanks!

I have the same issue with 4.8, Reinstalling the dacpac fixes the issue.
