Is it possible to alert on a string difference?  For example, I have created a script that gives an output of all windows services set to automatic not running.  If all services are running it will output "OK."  If there are services not running it outputs the displaynames of those services.

Unless there is a better way to monitor all services short of manually putting them in.

Hi!

You can check that current string value differs from previous value by using "diff" threshold. But this will not work as you need - you won't be able to check what part of string was changed and so identify what service is not running. Better solution here would be instance discovery or tables - but this requires list or table DCI with all services, which is not available either. My recomendation is to wait for 1.2.12 release - I will add Service list and table support to agent and you'll be able to configure what you need without additional workarounds.

Best regards,
