Nagios Support Forum

Hello Nagios support,
we have Nagios core version 3.3.1
We have a host group Inside host groups tab, we would like to delete that host group table, which include about 200 hosts.
What are the files i need to modify. I modified the host.cfg, hostgroups.cfg but not chnage is not effective .
Could you help, please.

Thank you

Since you're using Nagios Core, it really depends how your environment was setup. After deleting the host group from your configuration files, you'll need to run service nagios restart to have the changes take effect.

i was aware of restarting Nagios, but my concerne is not deleting the host , Inside host.cfg file
I want to delete the host group, which gather all the hosts in that TAB, and the tab calls HOST GROUP.

Thank you and Brgds

You can find where it's defined by looking at /usr/local/nagios/etc. Here's what I'd do, assuming your group name is ERICISGREAT: It will show you where the hostgroup is defined.

i am attaching a snap here so you can view the situation

Let's clarify - you would like to remove the "AIX - Non_production" hostgroup, correct? Have you tried grepping for it to see where it is defined?

Or, as I suggested, to find where it is defined (slightly modified, now that I know what group to look for):
