Nagios: DISK CRITICAL – /sys/kernel/debug/tracing is not accessible: Permission

If you receive the error above in Nagios, the workaround is to exclude tracefs from the check_disk command.

Login to your client server,

nano /etc/nagios/nrpe.cfg


find the check_disk and add –exclude-type=tracefs

It will looks like this:

/usr/lib/nagios/plugins/check_disk -e --exclude-type=tracefs
/etc/init.d/nagios-nrpe-server restart
