I have set up a few log shipping instances, but I am not a DBA.
This weekend something happened for the first time - the log shipping Monitor Server went down temporarily due to electrical issues outside of my control.
When I looked at the primary and secondary machines during this time, both were up and running and the .trn files were still being copied from the primary to the secondary, as expected. Yet, the secondary instance did not restore the .trn files at all. I received a notification:
The log shipping primary database _________ has backup threshold of 60 minutes and has not performed a backup log operation for 82 minutes. Check agent log and logshipping monitor information.
Is this expected? The primary and secondary were both running - shouldn't the monitor be an "optional" SQL instance which should have no effect on the log shipping? It was preventing the secondary instance from applying the backups even though I later explicitly ran the restore job. When the monitor server came back on, everything sorted itself out.
I have a lot to learn I know, any advice on whether I can check some settings or whether this is expected would be appreciated.
