Ubuntu / Nagios3 issue with receiving updates from custom Perl plugin

Posted on 2011-09-23
Last Modified: 2012-05-12
Hi Guys!

I'm a first time user of Nagios3 (or any Nagios for that matter).  I've successfully got the Ubuntu host of Nagios and 2 Windows Servers being monitored.
The 2 Windows Servers have iLO2 cards and I'd like to be able to monitor temps, fans etc.

Now I did some research online and came across this plugin;

which I installed (including having to install the Perl plugins as guided by the above link) and the iLO card but I am getting a "(Service check did not exit properly)" status (and hense a critical against the service).

The /var/log/nagios3/nagios.log says the following;

[1316793185] Nagios 3.2.3 starting... (PID=7867)
[1316793185] Local time is Fri Sep 23 16:53:05 BST 2011
[1316793185] LOG VERSION: 2.0
[1316793185] Finished daemonizing... (New PID=7868)
[1316793365] Warning:  Check of service 'iLO remote management card' on host 'iLO_RS2' did not exit properly!
[1316793665] Warning:  Check of service 'iLO remote management card' on host 'iLO_RS2' did not exit properly!
[1316793965] Warning:  Check of service 'iLO remote management card' on host 'iLO_RS2' did not exit properly!
[1316794265] Warning:  Check of service 'iLO remote management card' on host 'iLO_RS2' did not exit properly!
[1316794565] Warning:  Check of service 'iLO remote management card' on host 'iLO_RS2' did not exit properly!

I've checked the logs for the iLO card I'm trying to connect to and can't find any entry for the nagios user.

Now as I say I am very green when it comes to Nagios and so I do not know where to start on this.

Any ideas?

When you manually run the following command, what is the output -H <host> -u <username> -p <password>
  where <host> must be an iLO2 management controller!

Hi Wesly,

I got the following error message;

rs3@RS3:/usr/lib/nagios/plugins$ ./  -H rs2 -u nagios -p password
Can't locate IO/Socket/ in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at ./ line 78.
BEGIN failed--compilation aborted at ./ line 78.

Not entirely sure what that means but it doesn't look too promosing...?

I've checked the code for and the line is "use IO::Socket::SSL;"

I think I can see what the issue might be (correct me if I'm wrong) but it appears to be looking for elements of perl in;


The file in question being I think, but Ubuntu has the following layout;


so I guess the question is where can I change where it's looking....?

What's your perl version on Ubuntu?

which perl
perl -v

If "perl -v" shows "v5.10.1", then change the first line of to
   where is the output of 'which perl'

I've tried changing the #! entry to /usr/bin/perl as well as all of those listed above and basically got the following error message each time;

rs3@RS3:/usr/lib/nagios/plugins$ sudo ./  -H rs2 -u nagios -p password
./ 75: use: not found
./ 76: use: not found
./ 78: use: not found
./ 79: use: not found
./ 80: use: not found
./ 82: Syntax error: "(" unexpected

Am I doing something very wrong here (...probably)

This plugin requires perl modules "Nagios::Plugin, IO::Socket::SSL and XML::Simple"
Install those modules first.

sudo apt-get install  libnagios-plugin-perl  libio-socket-ssl-perl  libxml-simple-perl

Also post the line 75 ~ 82 of

Hi Wesly,

Ok, installed that double checked everything....

rs3@RS3:/etc/nagios3/objects$ which perl

so I've set the to #!/usr/bin/perl

output now is;

rs3@RS3:/usr/lib/nagios/plugins$ ./  -H -u nagios -p password
./ line 76: use: command not found
./ line 77: use: command not found
./ line 79: use: command not found
./ line 80: use: command not found
./ line 81: use: command not found
./ line 83: syntax error near unexpected token `('
./ line 83: `use vars qw($VERSION $PROGNAME  $verbose $warn $critical $timeout $result);'

line 76 to 81 is;

use strict;
use warnings;

use Nagios::Plugin;
use IO::Socket::SSL;
use XML::Simple;

and 83 is

use vars qw($VERSION $PROGNAME  $verbose $warn $critical $timeout $result);

I've attached the file but had to add a txt extention to be able to upload it to this website.  Perhaps if you can see the whole pl file it might help it make more sense...?

Found what was causing the problem, I thought I'd commented out previous #! entries at the beginning of the script, but it was still reading them.  I deleted them leaving just #!/usr/bin/perl and it's now working.
