OSX version of check_nfs_mounts?

[forrie]

We have a few OSX systems for which I must monitor for active NFS mounts, similar to check_nfs_mounts.sh on regular linux systems. OSX does things different, so it doesn't have /proc or /etc/mtab. OSX is admittedly not my area of specialty -- and I'm trying to find a way to monitor the NFS mounts so that Nagios can work properly.

Does anyone have any tips on how to accomplish this with OSX 10.9 (or 10.8)?


Thank you.

How about:

Code: Select all

 /etc/fstab

?

[forrie]

No, to check that they are actively mounted and operational. Not just configured.

Have you tried manually editing the plugin to fit your mount points??

[forrie]

Look at the plugin code. It calls to /proc and /etc/mtab -- as I explained above, these are not present in the OSX system. At least, I'm not aware of it stores this same information elsewhere.

I am not a mac guy either. One way I check mounts in gentoo is:

Code: Select all

mount -v

Or:

Code: Select all

mount -v|grep nfs

Does this work in ifruit land?

[forrie]

The person that set up the mounts has them in autofs, so the output looks like:

Code: Select all

/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)
map -static on /Network/prod/mezz (autofs, automounted, nobrowse)
map -static on /Network/test/mezz (autofs, automounted, nobrowse)
map -static on /Network/mezz (autofs, automounted, nobrowse)
map -static on /Network/dev/mezz (autofs, automounted, nobrowse)
/dev/disk1 on /Volumes/CF92 (msdos, local, nodev, nosuid, noowners)
/dev/disk2 on /Volumes/CF77 (msdos, local, nodev, nosuid, noowners)

In Linux, at least, you can check the active filesystems and their type in /proc and /etc/mtab

Since OSX is sorta BSD-ish (maybe less so these days) I figure there must be some facility in there -- that the microkernel refers to.

Not quite as clean, but have you tried using df -h or something similar and grepping for the specific mount point? Would this fit your needs of making sure its mounted and available?

[forrie]

df -h does not indicate the mount point type (ie: nfs).

I was hoping to discover some equivalent in OSX that stores this data, similar to mtab or /proc. That would be more accurate. But it's looking like Apple really changed things so much that nobody seems to know.

Did you create the mount point using the Disk Utility or you mounted it manually as root? If you did the latter, you *should* see something like: "192.x.x.x:/xxx/xxx on /xxx/xxx/xxx (nfs)", when you run the mount command.
