Host Groups / Definitions

[Shane Killian]

Thanks guys,

So for example I have the windows.cfg file.
I should define all windows servers here?

That file contains the following portion:
# Define a hostgroup for Windows machines
# All hosts that use the windows-server template will automatically be a member of this group

define hostgroup{
hostgroup_name              windows-servers              ; The name of the hostgroup
alias                        Windows Servers              ; Long name of the group
                }


Do I need to remove this?
Then, define each host group in the hostgroup.cfg file (I mean literally, a file called hostgroup.cfg file - I know that's a stupid question but I need to ask!).
Define the members in this file also.

Then in the windows.cfg file, under each process or service define each host group that the check should be run against e.g.

define service{
                use                                          generic-service
                hostgroup_name          Datacenter
                service_description         NSClient++ Version
                check_command                               check_nt!CLIENTVERSION
               }

Correct?


Kind Regards,

Shane

Gonna take a stab at this for you. Newer Nagios guy here as well. Here is a basic start....


You use a hostgroup.cfg file to create a group

i.e

define hostgroup{

        hostgroup_name          Remote_Hosts

        alias                           Remote Hosts

        members                 list names of all the windows servers here seperated by commas

        }

Now in your service.cfg or command.cfg file, where it says host_name, you replace the entire host_name line with the following :

#      host_name                              some windows server name

        hostgroup_name                  Remote_Hosts

Make sure your nagios.cfg file shows the path top the hostgroup.cfg file

Verify the config & restart/reload nagios.

Now the check you do will run against the hostgroup instead of a rambling list of hosts.

Hope this helps,

Steve

Hi guys,

I'm monitoring a number of Windows servers and so far I am using only the templates provided.

I would like to split my servers up using host groups so I will have each site and then the datacentre.
I'm not sure how to go about this... although I have read the documentation I'm not understanding.

Could someone please briefly outline this?



Thanks for your help!

Kind Regards,

Shane
