I have a few contacts that I am trying to delete but cannot because of this entry. Relation to tbl_host, entry - deletion not possible??
It doesn't show a host or anything so I am unsure which one is causing the problem.
I don't have any blank host ... any suggestions ?

This just means that the contact that you're trying to delete is defined as the contact for one or more hosts. You'll need to remove that person as a contact from the host configuration before you can delete the contact profile. This is to prevent an error when you attempt to Apply Configuration.

Right, but it doesn't tell me what host. Some of them do. But this one just says tbl_host, entry.
Others actually tell me which host the contact is attached to.

The orange 'info' icon next to the contact will display the table relationships.

Right, but it just says this:
Entry cannot be activated because it is used by another configuration:

Relation to tbl_contactgroup, entry ITSQL Group - deletion not possible
Relation to tbl_contacttemplate, entry xi_contact_generic - deletion possible
Relation to tbl_host, entry - deletion not possible
Relation to tbl_host, entry SDC Data Center Temp - deletion possible


What host is that one?

I'm not sure about the blank host entry, but I would remove the contact from 'SDC Data Center Temp' as well as the 'ITSQL Group' and then see if you can delete or if it gives you more information.

Yeah i did, and all is shows is the blank host.

I'd do a grep command to find out which host as that person as the contact. I'm still not sure why it's showing a blank name, but that's something we'll have to keep an eye out for. I'm not able to reproduce that as of yet.

Replace 'contactname' with the contact you're trying to delete:
This should return anywhere that contact is assigned to a host.
Note: Changes in the Core Config Manager don't show up in the config files until you Apply Configuration, so if you've got some working changes that haven't been applied, they may not be seen yet in the config files.

Replace 'contactname' with the contact you're trying to delete:

Code: Select all

cd /usr/local/nagios/etc/hosts
grep -n 'contactname'  *   

This should return anywhere that contact is assigned to a host.

Code: Select all

[root@localhost hosts]# grep -n 'nagiosadmin' *
CNN.cfg:22:     contacts                        nagiosadmin

Note: Changes in the Core Config Manager don't show up in the config files until you Apply Configuration, so if you've got some working changes that haven't been applied, they may not be seen yet in the config files.

Thankyou, i will try this!
