[Linux-cluster] Nagios agents, anyone?

[Birger Wathne]

Does anyone have an agent for nagios to monitor health of the cluster?
If not I'll write one myself. But what should an agent look for?
Of course nodes that are down/fenced are interesting information.
Quorum status is also nice to know.
Anything else?

I will of course monitor the services by having my nagios server act as a 
samba and nfs client, but those should only trigger an alarm if the services 
die completely.
