Icinga

We use Nagios' Fork Icinga for monitoring our servers.

Tomáš Pospíšek did the initial implementation, so he knows best how to configure that application.

To include a new check to Icinga, do the following:

Example of including a Swap check

1. The check needs to be configured for checking the Icinga Server (currently Staging)
2. The check needs to be configured for checking the Remote Servers (currently only Live)
3. The check needs to be executed for checking the Icinga Server (currently Staging)
4. The check needs to be executed for checking the Remote Servers (currently only Live)

Configuration

New Files

• local check (staging)
• /etc/nagios-plugins/config/swap.cfg

# 'check_swap' command definition
define command{
        command_name    check_swap
        command_line    /usr/lib/nagios/plugins/check_swap -w '$ARG1$' -c '$ARG2$'
        }

• remote check (live)
• /etc/nagios-plugins/config/swap_ssh.cfg

# 'check_swap_ssh' command definition
define command{
        command_name    check_swap_ssh
        command_line    /usr/lib/nagios/plugins/check_by_ssh -H '$HOSTADDRESS$' -C "/usr/lib/nagios/plugins/check_swap -w '$ARG1$' -c '$ARG2$'"
        }

Execution

  • /etc/icinga/objects/services_icinga.cfg

define service {
        hostgroup_name debian-servers
        service_description Swap
        check_command check_swap
        check_command           check_swap!75!40
        use generic-service
        notification_interval 0
}
