Multiple IP address check on same host

[log1c]

chek_icmp can ping multiple IPs and you can define how many should be reachable:

Dependency with two parents

check_icmp should be able to handle this and ping both addresses by adding a second one to the -H parameter and -m number of alive hosts required for success

check_icmp -H 8.8.8.8 9.2.5.99 10.10.10.10 -m 2

./check_icmp -H 8.8.8.8 9.2.5.99 10.10.10.10 -m 2 OK - 8.8.8.8: rta 9,166ms, lost 0% :: 9.2.5.99: rta nan, lost 100% :: 10.10.10.10: rta 19,070ms, lost 0% |8.8.8.8rta=9,166ms;200,000;500,000;0; 8.8.8.8pl=0%;40;80;; 8.8.8.8rtmax=9,549ms;;;; 8.8.8.8rtmin=8,910ms;;;; 9.2.5.99rta=0,000ms;200,…

Another possibility is check_multi:

Sounds like a job for check_multi.
