I am attaching screenshots of the incident, but we are monitoring our time clocks for our employees with TNM.
We didn't know one of the time clocks were down due to not getting a notification of a red monitor.
Is there anyway to prevent this? I checked for the obvious things such as the alert being sent to the wrong account, and that's not what happened. It just did not send. It also looked like there was only one notification of a red monitor via the monitor log attached. However, it was offline for over 12 hrs without notice.
Maybe it is due to the fact that the monitor didn't time out. Error received was "Destination host is unreachable".
Any help would be appreciated.
