I'm using the check_nrpe to check the space of the filesystems. The check_nrpe its able to check the space for all the volumes except one of them [root@nagios plugins]# ./check_nrpe -H <a href="http://vm.domain.com"> vm.domain.com</a> -c check_disk3 DISK UNKNOWN - free space:| disk3 is filesystem /dev/mapper/VolGroup01-infoVol00 which is mounted on /vservers/colombia/info. This is where the MySQL database reside. Why is showing DISK UNKNOWN - free space ?? This is how they are mapped: ===================== Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol02 138G 52G 79G 40% / /dev/md1 7.8G 153M 7.2G 3% /boot tmpfs 14G 0 14G 0% /dev/shm /dev/mapper/VolGroup00-LogVol00 16G 173M 15G 2% /tmp /dev/mapper/VolGroup00-LogVol01 16G 974M 14G 7% /var /dev/mapper/VolGroup01-infoVol00 119G 96G 17G 85% /vservers/colombia/info If I run the command /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/VolGroup01-infoVol00 from the server that its getting monitored it outputs the information ok like the following: DISK CRITICAL - free space: /vservers/fred/data 6113 MB (5% inode=99%);| /vservers/colombia/info =108694MB;96760;108855;0;120951 If I use the mount point when running the line from the monitored server it also gives the proper output. Now, If I use the check_nrpe with the check_disk option from the nagios server is when it give incompleted output like the following: DISK UNKNOWN - free space:| If specify the mount point in the nrpe.cfg of the monitored server and then run the check_nrpe with the check_disk from the nagios server. It gives the following: DISK CRITICAL - /vservers/colombia/info does not exist Any inputs?
