Is there plugin out there that monitors for status change on interface status?
Patrick Proys check_snmp_int is nearly what i want with its regex matching and such. Basically im looking for the same functionality, but instead of always exiting CRITICAL when an int is down Id like to cache the status. A WARN/CRIT would be issued if an interface has gone up/down since last check. This way I could use one service check of “^FastEth” on multiple routers and only alert when a previously working interface goes up/down.
