You might want to take a look at a general Nagios tutorial, as this can be quite an in-depth topic:

You will need to copy the plugin to your plugins directory and change the permissions if you need to. With most of the nagios plugins, you can run the "-h" or "--help" flag to view the usage, for example:

Code: Select all

/path/to/the/plugins/direcotry/<your plugin> -h

Test the plugin from the command line. After you make sure it works, you will need to create a command in the in commands.cfg file. Next, you will need to create a service definition. You can place it wherever you want (ususally in "/usr/local/nagios/etc/objects/" directory) as long as nagios can find it. Check your configuration with:

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Note: your paths may be different; adjust them accordingly.

You can find the Nagios Core documentation here:

http://nagios.sourceforge.net/docs/nagi ... n/toc.html

It can take a lot of work to get nagios configured, especially if you are new to it. If this is too difficult for you, try Nagios XI. It is a lot easier than Nagios Core. You can run monitoring wizards and the configs will be generated for you automatically.

Hope this helps.

/path/to/the/plugins/direcotry/<your plugin> -h

the path of the plugins directory can be this ? :

Code: Select all

/usr/local/nagios/libexec

for the permissions i will give them full permission to avoid problems.

Yes, can you execute your plugin with the -h to see if there is instructions on how to run from the command line?

Code: Select all

/usr/local/nagios/libexec/<your plugin> -h

Yes, the plugin format has not changed for quite some time. All of those should work with 4.x.x.

ok thanks , for now i have added this plugin just to test if i can put new plugins and make them work .

i added this one : http://exchange.nagios.org/directory/Pl ... ld/details (file .pl)

and i added this command in commands.cfg :

Code: Select all

define command{
command_name check_mysqld
command_line $USER1$/check_mysqld.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$
}

and this service in windows.cfg :

Code: Select all

define service { 
    use                             generic-service 
    hostgroup_name          mysql
    service_description      check SQL  
    check_command          check_mysqld!foo!apples
}

and in the web interface i find a new service called Check SQL , is that means that the plugin is successfully injected ?

That looks about right!

Give it a few minutes to see if it is running properly and check the output/status info.
