By default, Nagios looks like this:
Here's how you get custom icons working. It's quite easy. In my example, I will be using the standard icons, however there are lots of "icon packs" that others have created. You could also create your own if you wish.
First, check to make sure you have the images on your system.
monitor# ls /usr/local/share/nagios/images/logos/

ee /usr/local/etc/nagios/nagios.cfg
This contains the extended host information. You also must make sure that nagios.cfg references hostextinfo.cfg, on my system I had to comment out the following line.
cfg_file=/usr/local/etc/nagios/hostextinfo.cfg
After you've done that, now edit hostextinfo.cfg.
ee /usr/local/etc/nagios/hostextinfo.cfg
I've edited my file like this.
define hostextinfo{
host_name localhost,intranet,auth-server,spamd,mailhub,router1,snort1
notes_url http://webserver/hostinfo.pl?host=you_can_edit_this
icon_image freebsd40.png
icon_image_alt FreeBSD
vrml_image freebsd40.png
statusmap_image freebsd40.gd2
# 2d_coords 100,250
# 3d_coords 100.0,50.0,75.0
}
define hostextinfo{
host_name ad1,ad2,ad-test
notes_url http://webserver/hostinfo.pl?host=you_can_edit_this
icon_image win40.png
icon_image_alt Windows
vrml_image win40.png
statusmap_image win40.gd2
# 2d_coords 100,250
# 3d_coords 100.0,50.0,75.0
} Note: You can add your own coordinates for the status map.
After editing the file, save your changes, then restart Nagios.
Check to find the Process ID
monitor# ps -aux | grep nagios

You should now have custom icons. My example looks like this:
