[ubuntu] Nagios Error 127

[Hightower]

Just installed Nagios to see how good it is, and set up a networked printer as in the documentation.

 

It pings OK, but for Printer Status I get the attached error.

 

Installed on Ubuntu 8.04 Server, following documentation here:

 

Ubuntu Quickstart

127 normally means that it can't find or run the plugin you're calling, which I assume is check_printer or check_hpjd

 

Check permissions on the plugin - can the nagios user access it? Check the path you're using - on mine (compiled from source) it's :/usr/local/nagios/libexec/name_of_plugin

 

Run the plugin manually to check that the printer is responding:

./check_printer -H IPADDRESS -C SNMPCommunity

 

You should get: OK - Printer ok (" Ready") or similar.

Just had a look in /usr/local/nagios/libexec/ - there is not check_printer OR check_hpjd

 

How would I go about sorting this?

apt-get nagios-plugins

 

Will get you most plugins. However check_printer seems to of disappeared. So here's a better replacement.

 

NagiosExchange: check_printer - All in one printer check suitable for most devices

 

You also might want to have a browse around nagiosexchange for other plugins you might find useful.

Thanks for that Geoff. Looks good, if I can only find how to get it

[Hightower]

NM - got it

[Hightower]

Thought I had it. went to the plugin folder, did a wget http://www.ciphron.de/gfx/pool/check_printer and reloaded nagios

 

Thought this would have been it, any help?

[Geoff]

did you set it executable

 

also it appears to be written in php, thus you'll need the php CLI version installed.

I have set it as executable, and installed php5-cli

 

When i try to run ./check_printer in the same directory as the rest of the plugins I get a command not found.

[Hightower]

Just tried downloading and using another plugin. Downloaded it to the plugin directory, ran chmod -x pluginname and tried ./pluginname --help.

 

I'm obviously doing something wrong as I still get a Command Not Found error.
