This plugin for Icinga/Nagios is used to monitor NFS share I/O utilization on Linux hosts.

check_nfs_io's Issues

This script is broken for the newer versions of nfsiostat on Ubuntu 14.04 LTS

This check script works fine on most Linux distributions, however on Ubuntu 14.04 it isn't working. The script isn't capable of checking the values of the nfsiostat output, so no performance data shows up on the check output.

NFS I/O OK:  [Mount points: /var/www]|

It's nfsiostat command fault, because the values aren't being aligned with the columns they represent:

192.168.17.1:/var/www mounted on /var/www:

   op/s     rpc bklog
   0.60
       0.00
read:          
  ops/s        kB/s       kB/op     retrans     avg RTT (ms)    avg exe (ms)
          0.013

    453.392
       0 (0.0%)
     97.151
    120.760

Is there an easy patch I can do to adapt to this nfsiostat problem?

whitespace in performance data

Lines 331 and 334 in check_nfs_io/plugin-dir/check_nfs_io.pl have an extra whitespace between the value and the UOM in the performance data.
$perfstats .= "'" . $nfsshare . "_r_avg_rtt'=$value " . "ms;;;0; ";

should be changed to
$perfstats .= "'" . $nfsshare . "_r_avg_rtt'=$value" . "ms;;;0; ";
