[Linux-HA] crm_mon equivalent for serial and udp communications

[Matt Zagrabelny]

Greetings,

I am wondering if there is a program that can report on the health of
the lines of communication that the heartbeat module uses.

That is, crm_mon reports on the status of resources, is there something
similar that reports on serial and network interfaces used to send
heartbeats?

I am thinking something like:

Node1 /dev/ttyS0 - good
Node2 /dev/ttyS0 - good
Node1 eth2       - bad
Node2 eth2       - bad

Would indicate that the crossover cable connecting eth2 on Node1 and
Node2 was disconnected or equivalent.

Thanks for the info,
