Re: AppInsight for SQL Alert for Last Backup

I believe that this can be done by "Custom SQL Alert" defined over "AppInsight for SQL: Database" object using condition similar to:

WHERE  
(  ( APM_SqlBbDatabaseAlertsData.RecoveryModel = 3 AND DATEDIFF(HOUR, APM_SqlBbDatabaseAlertsData.LastBackup, GETUTCDATE()) > 25)  OR  ( APM_SqlBbDatabaseAlertsData.RecoveryModel = 1 AND DATEDIFF(MINUTE, APM_SqlBbDatabaseAlertsData.LastBackup, GETUTCDATE()) > 20)
)

Image may be NSFW.
Clik here to view.

For recovery model values see documentation (sys.databases (Transact-SQL)):

1 = FULL

2 = BULK_LOGGED

3 = SIMPLE
