Can you edit the host and set the alias to something else (anything other than blank), apply config, and then see if it changes?
If that doesn't work, please go to Configure > Core Config Manager > Tools > Config File Management:
- Click the Delete Files button (don't worry, it's safe, they will be rewritten)
Once you've done that do you see the
/usr/local/nagios/etc/hosts/YOURHOSTNAME.cfg file removed now?
If not, please manually delete it:
Code: Select all
rm /usr/local/nagios/etc/hosts/YOURHOSTNAME.cfg
Then click the Write Files button, then apply config.
If none of that works me may need to setup a remote session to debug.
Please create a ticket for this and include a link back to this forum thread so we can get a remote session setup:
