Where to store custom check programs

[moose]

Standard Nagios check programs are stored in /usr/local/nagios/libexec. Which folder do I use to store my custom check programs?

Defining my check program. Does it get defined it in /usr/local/nagios/etc/commands.cfg or do I define it in a new file /usr/local/nagios/etc/static/myKoolCommands.cfg?

I also have to notify Nagios of myKoolCommands.cfg. Do I insert cfg_file=/usr/local/nagios/etc/static/myKoolCommands.cfg into /usr/local/nagios/etc/nagios.cfg or some other file?

Restart Nagios with "service nagios restart"?

Is there anything else I have to do to get Nagios to recognize my program?
Thank you

Wherever you want. I usually create a folder inside libexec for my custom check scripts.

Defining my check program. Does it get defined it in /usr/local/nagios/etc/commands.cfg or do I define it in a new file /usr/local/nagios/etc/static/myKoolCommands.cfg?

Either once again. Just remember that any new config you create has to be declared with and include statement in the nagios.cfg file.

I also have to notify Nagios of myKoolCommands.cfg. Do I insert cfg_file=/usr/local/nagios/etc/static/myKoolCommands.cfg into /usr/local/nagios/etc/nagios.cfg or some other file?

Exactly.

Restart Nagios with "service nagios restart"?

Yep.

Is there anything else I have to do to get Nagios to recognize my program?

As always, it depends on the plugin in question.

Nagios does not offer my plugin in the CGI. CCM> Services> AddNew> CheckCommand combo box.

As a test I have duplicated and renamed one of the plugins that comes with Nagios check_mssql to become check_ts. Here's what I've done do far.

Made a sub-folder for the plugin /usr/local/nagios/libexec/ia

Copied /usr/local/nagios/libexec/check_mssql into /usr/local/nagios/libexec/ia/check_ts

Created a new command file /usr/local/nagios/etc/static/ia_commands.cfg

Code: Select all

# Contents of ia_commands.cfg 
define command {
command_name	check_ts
command_line	$USER1$/ia/check_ts -H $HOSTADDRESS$ $ARG1$
}

File /usr/local/nagios/etc/nagios.cfg already has cfg_dir=/usr/local/nagios/etc/static which loads my ia_commands.cfg. No changes to nagios.cfg were made. I've also tried specifing ia_commands.cfg in nagios.cfg and got an error for duplicate definitions.

The pre-flight check found ia_commands.cfg and shows no warnings and no errors.

"service nagios restart" stopped and started without problems.

I reloaded the CGI page.

Is there some other setting I have to make?

Can you run the check from the cli?

Thank you.
I followed the PDF and Nagios recognizes the plugin and it appears in the combo box. Adding the plugin manually was a waste of time. I'll just use the CGI from now on and be resigned to never knowing why the manual method didn't work.

... the plugin did run on the CLI because it was a standard plugin; just renamed.

I'm glad your problem has been resolved.

With XI, it is best to stick to the web ui for most things. Not to say that the static directory doesn't have a place for some installs, but if you can use the ui, it is better as then you have the db backend and some advanced validation and logic for checking your configs.

Glad to hear you got it working. Locked.
