I'm looking for one (or more) snmp mib variables that gives me quick and short the information, if our Cisco routers are running OK or NOK. I have to implement an SNMP-based application to poll network devices and analyze the device status (result is only ok or nok at this level). For more detailed analyzing of the problems, we use CiscoWorks 2000. My goal is poll as few as possible mib variables.
Unfortunatelt, there isn't any general purppose health check mib object that you can poll on the router. For polling interface status you can use ifOperStatus/ifAdminStatus from RFC1213-MIB
