Nagios Check_nrpe/check_disk with error message DISK CRITICAL – /apps/yourxxx is not accessible: Permission denied

June 21st, 2011 1 comment

This was sometimes because the user under which nagios runs by had no read permission to the file systems check_disk is going to check.

For example, if you received alert:

DISK CRITICAL – /apps/vcc/logs/way is not accessible: Permission denied

You then can log on your server, under root, run:

/usr/local/nagios/libexec/check_disk -p /apps/vcc/logs/way, you may see:

DISK OK – free space: /apps/vcc/logs/way 823 MB (21% inode=90%);| /=2938MB;;3966;0;3966

But when you run this under user nagios, you may see DISK CRITICAL again.

Resolution:

Grant read permission to the filesystem/directory that had problem.
