This plugin uses DISMAN-EVENT-MIB::sysUpTimeInstance which expresses uptime in 1/100 sec in a 32-bit value. So it will roll over in 496 days and may result in spurious alerts at that time.
If your device supports SNMP-FRAMEWORK-MIB::snmpEngineTime.0 (.1.3.6.1.6.3.10.2.1.3.0) that OID's result is expressed in seconds and can be monitored by simply using check_snmp.
check_snmp -H router -C public -o SNMP-FRAMEWORK-MIB::snmpEngineTime.0 -c 2000

Thanks for sharing this plugin. We're using it to monitor a few dozen Cisco switches. It was very simple to deploy and has accurately identified problems.

This plugin has proven extremely valuable in detecting errors on redundant links. We're using it to monitor 600 inter-switch trunks on Cisco, Force10 and Dell switches.
