I see that it is very easy to monitor the stoppage of a continuous presence/process/service.
How would I go about monitoring/alerting if a given event does not occur when the event is randomly scheduled and non-continuous?

We have a Windows scheduled task that is supposed to run every 5 mins. I would like to get a PRTG alert when it does not run as scheduled.
If necessary, we can have the task deposit some residue after it runs either in the form of a change to a file/log or into one of the Windows event logs, if that would help.

You could have the scheduled task write or change a "log file" and then check this file with a file sensor in PRTG, and then set a trigger on the "age" of the file, to alarm if it's older than 5 minutes.

I think that could work.
Would the trigger be a "Threshold" trigger and the channel be "Last Modified"?
If so, what does the value in the trigger "Value" field represent (i.e. What does a value of 5 mean as related to a channel of "Last Modified")?
If not, what trigger/channel should I be using? Thanks.

Yes, the trigger would have to use 'Last Modified' and you will probably have to enter the value in seconds, i.e. 300

Hello,
that is very hard to say. Can you provide more details please?
Best Regards.
