PRTG Network Monitor File Sensor -- notification if no changes detected?

[Cerulean]

Greetings!

Is there a way to have PRTG Network Monitor send an e-mail notification if it detects a specific file to not have changed?

We have a log file that needs to be monitored and for an e-mail notification to be sent out if it stops growing. If it stops growing, it means a part of the system is down. To clarify, not all components of a system being down are easily observable by users nor will they always report to us something isn't working. Sometimes jobs queue up due to the system processing too much, and it is possible for jobs to queue up because another component is hosed but must be manually checked by someone in our department to confirm.

It would certainly make it easier if we received a notification if a log file stopped changing in file size as it should be constantly.

I don't know if prtg will, something like knowledgesync might have a file watcher ability.

We found a way

When configuring the object trigger (for notification), we used a Threshold Trigger:

When Last modified channel is Above 900 for at least 60 seconds perform Email to all members of group PRTG Users Group

When condition clears after a notification was triggered perform no notification

What that says is that if the last modified timestamp exceeds 900 seconds duration (of when the file was last modified vs present time) and stays that way for at least 60 seconds (beyond the 900 second duration), then to send an e-mail alert.
