Nagios NRPE Disk Check Error on Plesk

If you’re monitoring a server with Nagios NRPE that is running Plesk, you might have run into the following issue. The disck_check command may return the following lovely error message.

DISK CRITICAL – /var/named/chroot/etc/named is not accessible: Permission denied

The fix is rather simple, you just need to modify the /etc/nagios/nrpe.cfg file and change your disk_check command to include the following

-x /var/named/chroot/etc/named -x /var/named/chroot/var/named -x /var/named/chroot/etc/named.rfc1912.zones -x /var/named/chroot/etc/rndc.key -x /var/named/chroot/usr/lib64/bind -x /var/named/chroot/etc/named.iscdlv.key -x /var/named/chroot/etc/named.root.key

Which will exclude the chrooted locations that the NRPE daemon doesn’t have access to it.

Some of the popular press and blogs have been backing the opposition. :-) While criticism and competition is fine it should be reported correctly, with all the facts. and certainly minus the FUD. Do you guys think we are “less and less relevant with each passing day” ? We don’t think so, and we certainly prefer our hacks to theirs. ;-) Though even if the world deems us irrelevant, the iPhone family of devices is still fun to hack!
