Error / Resolution¶

CASE 1 :¶

Error : DISK CRITICAL check_disk : / / / is not accessible: Permission denied

Solution : In my case this is because it is mounted as postgres user.
Which eventually does not allow other user (nrpe or nagios) to check the disk.
So i have copied the command as diff. name and set the SUID bit on the check command.

cd /usr/lib64/nagios/plugins/
cp check_disk check_disk_pg
chmod +s check_disk_pg

Voila...!!
