How to Display Nagios Host Custom Variables or Macros in the Web Interface

nagios

How can I display custom host variables in the Nagios web interface such as _mac_address?

Best Answer

You can do this using the notes directive inside of the host definition even if the variables are also defined their and they will show up in the host detail page (extinfo.cgi). For example:

define host {
        host_name web01
        display_name web01
        address 8.8.4.4
        _mac_address  00:21:9B:00:21:9B
        _sw_port_1    sw01_g3
        notes $_HOSTMAC_ADDRESS$ $_HOSTSW_PORT_1$
        hostgroups +webservers
        use web_servers
}

Displaying Nagios on a 52″ 1080p screen

I would highly recommend nagvis from here. This is a tremendous tool to display nagios data (from multiple nagios instances, if you want to) in a meaningful way. We also have such a TV on the wall, and we have around 10 different maps (that's like pages with diagrams and icons on it) rotating every 15 seconds. It's absolutely magic.

You will need some time to configure it, but the results are stunning. The screenshots on the site are only a small example of what can be done. If you have any questions about it, just fire away. We have about 200 hosts and 800 services in nagios across 3 sites, so there is very little I haven't done with nagios/nagvis.

How to add a host in icinga-web

To add a host, you must define it first, e.g linux.cfg:

define host {
    use                 linux-server
    host_name           s80
    address             x.x.x.x
    check_command       check-icmp
    contact_groups      admin
}

(Do the sames for all services which you want to monitor)

Insert full path to this file into icinga.cfg:

cfg_file=/usr/local/icinga/etc/hosts/linux.cfg

Verify your configuration with:

# /usr/local/icinga/bin/icinga -v /usr/local/icinga/etc/icinga.cfg

and restart Icinga:

# /etc/init.d/icinga reload
