  Used to use Observium + SNMP, found this https://bugs.launchpad.net/ubuntu/+source/net-snmp/+bug/1403730 but never got around to applying the patch and switched to check_mk anyway. Might work for you

  Is snmpd actually providing this information?

  Walk the disk oids and see what you get. You may have a config error on your snmpd.

  Give the above link a try.

  Especially on:

  @markturner No I don't think SNMPd is providing the info, guess I'll have to either patch it or extend it with an addon script

  Compiled net-snmp from source and it's working now, Ubuntu package doesn't have the required FS support to be able to read it it seems.

  Also it's a bit of a pain to remove once installed it left behind a library that was being used instead of the one I compiled so I kept getting the wrong SNMPD version reported (5.72 where i'd built 5.73)

  I originally submitted the simfs patch to launchpad, what I did to test it was

  apt-get install devscripts build-essential
  apt-get build-dep snmp
  apt-get source snmp
  cd "net-snmp-5.7.2~dfsg/debian/patches"
  wget "https://bugs.launchpad.net/ubuntu/+source/net-snmp/+bug/1403730/+attachment/4370006/+files/fix_simfs_detect.patch"
  echo "fix_simfs_detect.patch" >> series
  ## LP managed to strip off a space at the bottom of patch -_-
  sed -i -e '$a\' fix_simfs_detect.patch
  cd ../../
  dpkg-buildpackage -uc -us
  

  Edit: Fixed the fact that there is a missing carriage return at bottom of patch, and replaced debuild for dpkg-buildpackage to remove the need for a GPG key.

  Package should be pinned unless you want any updates to the package in the repository to wipe this one out.
