How do i add a service to nagios?

Question

I asked this question and i'd like to add the service to nagios. nagios is being very strange. I edited /etc/nagios3/conf.d/localhost_nagios2.cfg and changed the text "Current Users" to "Current UseTESTrs" and restarted nagios. It looks like i am editing the right file. It disappeared. I dont know why it didnt just change the text of the description. I hit undo and restarted and the service is still gone. I tried the same thing with total process and that also disappeared rather then rename and undoing/restarting nagios didnt help bring it back (wtf)

So.... I have no idea whats going on but how do i restore those two services and add the check http command to check my 3 website to see if its working or giving me an error (usually a 5xx error)

It looks like i am editing the right file.

You can create any config file and make it takes effect by defining cfg_file or cfg_dir option in the main config file (nagios.cfg):

cfg_dir=/etc/nagios3/conf.d

I dont know why it didnt just change the text of the description. I hit undo and restarted and the service is still gone.

You probably should verify the config before restarting nagios service:

# nagios -v /path/to/nagios.cfg

How do I add the check http command to check my 3 website...

Define a command in /nagios_prefix/etc/objects/commands.cfg:

define command{
    command_name    check_http_status
    command_line    $USER1$/check_http -H $ARG1$ -u $ARG2$ -e $ARG3$
    }

and add a service:

define service{
    use                     generic-service
    host_name               web1
    service_description     web1/uri
    check_command           check_http_status!domain.com!/uri!200
    contact_groups          admin
    }
