Nagios Support Forum

Fantastic! If it doesn't happen today, we're here every week day. No hurry.

Thanks I have configured nagios to work by adding individual host but that gets to be too much when you need to add alot of host so that is why I am hoping to get this figured out and thanks for your help and quick responses

Absolutely! That's why hostgroups exist!

I removed the contact group but this part isn't clear where you said to add hostgroup to the host and create a contact group

Reading configuration data...
Read main config file okay...
Error: Could not find any host matching 'TFS-BUILD001' (config file '/usr/local/nagios/etc/objects/hostgroups.cfg', starting on line 5)
Error: Could not expand members specified in hostgroup (config file '/usr/local/nagios/etc/objects/hostgroups.cfg', starting on line 5)
Error processing object config files!

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.
This host is added as a member in the hostgroup and I removed the contacts group from the hostgroup.cfg

Do I need to have another config file with the individual host or having the host in the hostgroup file is okay. It can't find the host even though the host is in the hostgroup.cfg

Please post your updated configs so we can see what is going on.

Separate config files are not necessary.
