External Plugins Not working

[nathanplatt]

Hi Guys,

I just migrated Nagios from Ubuntu to Centos and have had a few problems, here are the ones that aren't playing;

(No output on stdout) stderr: Can't locate Net/SNMP.pm in @INC (@INC contains: /usr/local/nagios/libexec /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/nagios/libexec/check-netapp-ng.pl line 40.

UNKNOWN: check_snmp_printer: No usable 'bc' binary in '/sbin:/usr/sbin:/bin:/usr/bin'

(No output on stdout) stderr: Can't locate Net/SNMP.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/nagios/libexec/check_qnapdisk line 25

So in an attempt to fix this, i installed CPAN and ran the following;

cpan install Monitoring::Plugin
yum install perl-Nagios-Plugin

Then i restarted nagios and httpd, but i'm still getting the errors. Any help would be appreciated

[nathanplatt]

Right, i've managed to fix almost all of these, but i'm stuck in two areas:

Nagios Graphs.

I have the following error

JavaScript is disabled.
nagiosgraph.js is not installed or wrong version.

The rrd files are collating, the config seems fine, the js file is located in /usr/local/nagiosadmin/share/

And check_snmp_printer;

UNKNOWN: check_snmp_printer: No usable 'bc' binary in '/sbin:/usr/sbin:/bin:/usr/bin'

You can run this to install bc on your server to fix that issue.

Code: Select all

yum install bc -y

Take a look at this like for help on the nagiosgraph issue.

Okay, so i installed bc and then it said I was missing xxd, so i googled and installed vim-common and vim-enhanced, now all those items have disappeared from Nagios completely.

As for the issues with nagiosgraph.

I moved the js and css to the nagios/share folder and the graph now shows but i'm still getting the same errors at the top. If i navigate to a host graph directly it works but I can't choose the servers from the how.cgi menu.

Any other ideas?

Okay, so i've fixed the external files, but the graphs still aren't working.

[tgriep]

Can you screen capture what the issue is and post it here so we can view it?
Have you searched here to see if there is a fix for the issue?
https://sourceforge.net/p/nagiosgraph/discussion/394748

[nathanplatt]

You can see from the attachment that the graph is loading and working, but I keep getting the error at the top.

I have the nagiosgraph.js and css file located in the /usr/local/nagios/share/ folder, when i moved them there i can see the graphs but the error appears still.

I ls -l on the folder and found that both the nagiosgraph files where root root, so i've chown them to nagios:nagios but i still get the error.

This is the same error, but there's no solution https://sourceforge.net/p/nagiosgraph/d ... /e7e3d3ba/

The nagiosgraph.conf file has the following;

Code: Select all

# JavaScript: URL to the nagiosgraph javascript file.
javascript = /usr/local/nagios/share/nagiosgraph.js

# Stylesheet: URL to the nagiosgraph stylesheet.
stylesheet = /usr/local/nagios/share/nagiosgraph.css

I'm guessing the config is really messed up, here is the report from showconfig.cfg

Hopefully that's everything you need. Sorry for such a long post

[nathanplatt]

I've resolved this, i didn't realise that the value of Stylesheet and Javascript is the url not the path, changed this and its now working correctly
