  Hello

  Is there any good query available to find when the AG mode is changed from Async to Sync? Unable to easily find it from the errorlog.

  Any good Tsql to filter the data would be helpful.

  Thanks.

  Did you check default trace and/or system_health xe session ?

  You can monitor your AG(s) with extended events:
