Nagios3 server and client installation (Squeeze)

На стороне сервера nagios

aptitude install nagios3 nagios-nrpe-plugin
aptitude install nagios3-doc

Поправить
/etc/nagios3/apache.conf says
DirectoryIndex index.php
but has to be
        DirectoryIndex index.php index.html

Добавим уведомления по почте:
aptitude install mailutils postfix
Поправим /etc/postfix/main.cf:

relayhost = mail.example.com:25

smtpd_use_tls=no 



touch /etc/nagios3/conf.d/test.cfg
define host {
    use             generic-host
    host_name       repo
    alias           repo
    address         172.16.0.122
}

define service{
    use                             generic-service   
    host_name                       repo
    service_description             Total Processes
    check_command                   check_nrpe_1arg!check_total_procs
    }

define service{
    use                             generic-service
    host_name                       repo
    service_description             Current Load
    check_command                   check_nrpe_1arg!check_load
    }
