While trying to use a Nagios plugin I got an error saying that “Can’t locate utils.pm in @INC”.

Following is complete error:

Can’t locate utils.pm in @INC (@INC contains: /root /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .)

This issue is occurred due wrong library path in Nagios Plugin(Perl Script).

When I checked library path in script its given as ‘use lib “/usr/local/nagios/libexec”;’ where path /usr/local/nagios/libexec is not exists in our os.

All our library’s are available in path “/usr/lib/nagios/plugins”, so I changed lib path in my script to “/usr/lib/nagios/plugins”. After changing the path Nagios Plugin is worked without any issue.
