Monitoring router with check_snmp

[Hendrik Baecker]

Hi Matt,

SNMP is the best way, I think.

Other examples may:

check_icmp to check the routers IP adress and/or their sub interfaces.
check_tcp to check if the telnet / ssh / web port is open and answering
write or look for a perl script, that can telnet the router, give some 
commands to the router and check the output if the output is what you 
want to see.

Beware of the last option, you have to work with the login of your 
router. Don't know how you're thinking about security.

Best wishes
Hendrik
