Closed mgusek closed 7 years ago

mgusek commented 7 years ago
Hi, i'm trying your monitoring solution. One think looks unclear: Check 'Backup Status dell_live_3' shows status 'OK - There is a valid backup' but in our Logs we can see, that the last backup was not successfull: ` 2017-08-31 03:29:39.980822 Error dell_live_3 pddserver(1.0): Backup error.

` Service check 'Backup Status' should take that into account.

Hi,

the check_backup.py script only checks, if there is a restorable backup available within the last 7 days (preconfigured). It does not check if a backup fails or not, it just to be sure that on your storage is a backup for a worst case scenario available.

But you should definitly got an alert from the log service script when the backup fails.

Kind regards
