Nagios Core 3.5>>>Cannot see network

On my Nagios Core 3.5 web interface...when clicking map. I only see the graphic Nagios process and localhost.
How can I get Nagios to recognize the localhost or any other node on the network?

You said when you look at the map you see the localhost but then you asked how do you get Nagios to recognize the localhost.

Do you see the localhost when you click on the map. How many other hosts do you have configured?

yes, I do see localhost(127.0.0.1).  I have create & configured(populated) the host.cfg file service.cfg and placed them in the /usr/local/nagios/etc/objects.

When you click on Hosts right below the MAP link how many hosts do you see there in addition to Localhost.

RickEpnetCommented:
Your hosts will not show on the MAP until they show up under the Host link too. Did you restart Nagios when you updated the config files?

gumball60Author Commented:
yes... I can now see network switches....but nothing else

RickEpnetCommented:
Let's get some more information.

1. When you say see the switches do you mean under Host or On the Map page or both?
2. What type of devices do you have Nagios setup to monitor?
0
gumball60Author Commented:
It was both.  I have it set up to monitor switches, servers, workstations, backup servers, etc.
I can now see other devices...
Most of the devices are are not mapped properly and displaying service issues.

First of all regarding the Warning
Nagios is saying that it's unusual to monitor a device just for its
existence on the network, without also monitoring some service.

The way the map displays is directly related to the parent / child relationships of the hosts.
Make sure your parent child relationships are the way they are supposed to be and it should display fine.
