Simple Sensor to query SQL error log strings

we want to monitor failures of the backup jobs running at a SQL server instance. For now we set the sp_readerrorlog procedure as a starting point to get the information from the log.

EXEC sp_readerrorlog 0, 1, 'flush', 'failure'

This is an example how the procedure output look like: 215 | 2021-06-25 13:331:02.750 | spid59 | BackupVirtualDeviceFile: RequestDurableMedia: Flush failure in device 'EMC#ea45d....'

Question is, does an easy solution exists within PRTG to throw a notification when the above "fail" strings are detected?

prtg query read-error-log sql

Hello,

I assume that the string changes over time (since it contains a time and date). If that is the case, then you will not be able to monitor the result, since the SQL sensor can not perform a string search.

There is a workaround that would allow you to show strings in a SQL sensor, however this works only if you have a limited number of strings and they are always the same.
More information about this can be found here.

If you can perform the string search in the procedure, and return a numeric value as a result (0 for sting not found, 1 for string found), I would recommend to use that.
A other alternative would be to create a custom script that would do the string search and run it with one of our custom sensors.


Kind regards,
