You can use Universal Device Poller and OID sysUpTime.0
The Universal Device Poller is in Orion. The equivalent in ipMonitor would be the Custom SNMP Monitor. Simply go to Devices -> All Managed Devices, select the Device in question and click Add -> Add New Monitor. On the right-hand side, click "SNMP", on the left-hand side, click "Custom SNMP (Wizard)". The sysUptime OID should already be entered. Ensure the correct address and community name is entered and click 'Next'. Follow through the rest of the wizard and that should be it.
Hope this helps.

Keep in mind that the sysUpTime OID counter is in 100ths of a second, so you'll need to use that factor to determine the hours or days a system has been up.
So along the line of this thread I got uptime from using the SNMP monitor setup and 188.8.131.52.184.108.40.206.0
My question is how do I save this monitor as a template? (i.e. How do I get this monitor in the list of manually addable monitors?)
