Where are my imported hosts?

[danoreilly]

I imported a file of several hundred hosts from a Nagios core implementation I was using, in order to do an eval of purchasing Nagios XI. The import went fine, but the hosts display only shows "localhost". I know the hosts are someplace, because I can look one up and see that contacting it is failing (but that's another topic). If it look at /usr/local/nagios/etc/hosts, I see the correct host config files for everything. Why can't I see any of my hosts in the host display?

PS - I forgot configuration info. I'm running the Nagios-supplied VM image under VMplayer, all under RHEL 6.

Did you apply configuration through the GUI?

Was it successful (3 green checks)?

[danoreilly]

Yes and yes. Everything seemed to be OK.

If you go to a Nagios Core view do you see the hosts/services?

Code: Select all

http://HOST/nagios/

[danoreilly]

yes

Lets forcibly restart ndo2db

Code: Select all

service ndo2db restart

If they still do not show in the UI, can you post the output of

Code: Select all

grep module /usr/local/nagios/etc/nagios.cfg

We may need to setup a remote session to take a look at the server.

Did you get a chance to test what scott mentioned? It looks like you just quoted him at the moment.

After the first thing (restarting the db) failed, I didn't try the second. I can do that.
