when we did custom monitor in that we given the OID: .1.3.6.1.2.1.1.3.0 the result is like this:
Test results The Monitor responded to the test request Summary Device Name 192.168.0.5 Monitor Name Uptime-4 Protocol SNMP OID .1.3.6.1.2.1.1.3.0 Monitor value 1224067 Units
In the place of system uptime we are getting some miscleneous value "1224067".
