I am trying to monitor a log file for a Windows service to ensure that the service is executing. Unfortunately, I cannot get a heartbeat out of the log, though there are entries almost constantly added. So what I would like to do is alert on the file when is DOES NOT grow since the last check. I could not find a way to do that...I can alert on increase or decrease, but not on "unchanged". Is there a way that this could be done without resorting to custom code?
