Currently, we are monitoring ASA uptime using SNMP OID 1.3.6.1.2.1.1.3.0 (systemuptime) and we get a reboot alert after uptime crosses 1 year 132 days +. though the device doesn't reboot in actuality. It appears that this OID is a 32-bit counter which rolls over after 496 days and hence the reboot alert.
Somewhere it was suggested to use another OID enginetime 1.3.6.1.6.3.10.2.1.3.0 instead of systemuptime to track the uptime of the device, but in case of a failover pair, it tracks the cluster uptime and not the individual firewall.
Any ideas please?
