List All Mount Points

Use the bdf command in UNIX to list all mount points (including the NFS mounts) on your system.  You can parse the output from this command to monitor NFS mounts and confirm they aren't stale or non-existent.

Keep in mind that error messages are displayed to the terminal, and not inline within the command report output.  For this reason you can't search for the error message, but you can confirm the non-existence of the particular mount point and report on that.
