Nagios script request - nagiostats

knobdy · Post by **knobdy** » Tue Nov 14, 2006 12:47 pm

I see that nagios has an executable called nagiostats that will dump data into mrtg format - is it possible that this will provide nagios statistics we could graph in Cacti?

I would also like to see this supported.

I'm taking a stab at writing a wrapper script and creating some templates to handle this. I'll post my results if it turns out well.

Okay, here's what I've come up with. First, my Nagios and Cacti instances both sit on the same box, so the wrapper script that returns data from nagiostats is run locally. If your Nagios instance sits elsewhere, you'll have to retool this a bit.

To use, first place the attached script in your cacti scripts directory. Second, alter the following section of the script to fit your Nagios configuration:

Code: Select all

# nagios binary and configuration locations
my %nagiostat = ( 'bin' => '/usr/local/nagios/bin/nagiostats',
                  'cfg' => '/usr/local/nagios/etc/nagios.cfg');

Third, import the graph templates you wish to use. Finally, create new graphs on localhost and assign the just imported templates.

This is my first attempt at exporting, so please be gentle if this blows up

. Don't hesitate with comments, questions, or suggestions.[/code]

I installed all of this but no go... CMD partial error in the Cacti logs... So I did the following:

- append the Data Input with /usr/bin/perl and still not working
- checked script runs OK via command line, script runs fine, results are expected.

Not sure where to go from this point....

Is there any more detail in the cacti log?

Unfortunately, no...

Got the same error. Script via command line works:

./nagiostats_parse.pl SVCCOUNT
NUMSERVICES:110 NUMSVCOK:103 NUMSVCWARN:3 NUMSVCUNKN:0 NUMSVCCRIT:4

I'm stumped on this one. I'm not sure what that error message indicates. Are you both on version 0.8.7b? Can you paste the errors in their entirety?

I ran Cacti in Debug logging mode... Shows the full command with the same result, which is a "U" like it's processing the "Die" portion of the script. Run the script manually, no problems...

The source code contains:

Code: Select all

cacti_log("Host[$host_id] DS[$data_source] WARNING: Result from CMD not valid.  Partial Result: " . substr($output, 0, $strout), $print_data_to_stdout);

which means it should be printing out the results from the poller in the error message. In this case it appears to be returning nothing. So either the script isn't being run, or the results are lost in translation somewhere. The script is definitely located in <path_cacti>/scripts with the executable bits set? If you prefaced the command with /usr/bin/perl that probably wouldn't matter, but it's a shot in the dark.

Tried that, no go... Same results either way.

Maybe a userrights issue?

Cacti and Nagios running from different users.
