Did you compile the nagios plugins package on this system? It looks like you are missing the Utils perl module. Can you attach your plugin? I'd be interested in seeing it's USE definition, since you have a fairly unstandard directory for your plugins I would not be surprised if it is looking in the wrong location. Does the file "utils.pm" exist in your plugin directory?

[brandon.pal]

From what I know our prod sys admin did this:

Code: Select all

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
yum -y install nagios nagios-plugins-all nrpe 
chkconfig nagios on

Does the file "utils.pm" exist in your plugin directory?

/usr/lib64/nagios/plugins/utils.pm

I'd be interested in seeing it's USE definition

Code: Select all

use Getopt::Long;
use vars qw($opt_h $PROGNAME $opt_w $opt_c $opt_t $opt_vi $msg $state);
 use lib "/usr/local/nagios/libexec";
use utils qw(%ERRORS &print_revision &support &usage );

[slansing]

Try changing:

Code: Select all

use lib "/usr/local/nagios/libexec";

To

Code: Select all

use lib "/usr/lib64/nagios/plugins/";

Then run the commands lmiltchev posted above, again, thanks!

Yeah yum is a really easy way to install applications, unfortunately on a system to system basis and package to package, the directory structure or contents of the package can change. That's why I usually recommend compiling the plugins by hand.

I'll be honest. I have no idea how to do that.
