I need some advice wrapping my head around this. ICMP is blocked on several servers, but I can "Tenet" to those clients on port 3000. Is there a way I can setup a Telnet test that will periodically login to see if it can connect to that server and port WITHOUT creating endless telnet sessions from those servers?
I am not sure exactly what you are trying to check for or monitor.
However, it sounds as though you may want to check out Classic Monitor > External Monitoring > System Check > Port Connection Check, if you have not already:
If you have already tried this, perhaps more details on the exact conditions you want to monitor on these devices may help us point you in the right direction.
Duh!!! I knew this.... I gotta start drinking the Caffeinated coffee
