Verifying NFS mounts to a local Mac?

[forrie]

Where I work, we primarily use Linux systems and Nagios to monitor them. The way we monitor via Nagios for NFS mounts on a client system will not work with OSX (/proc, /etc/mnttab, etc). I admit my OSX tech skills are not yet up to par, but we do have a couple of these that are in production that I must monitor.

So my question is how can we reliably monitor and check for local NFS mounts (not exports, it's not running NFS server) on OSX 10.8? I would need to write/alter a script for Nagios to accommodate this -- oddly, I've not found anything on Nagios forge.

Thanks!
