Hosts missing from objects.cache

[MKEbrew]

I am unfortunately still on Nagios 3.2.3 which I know had some issues.

That said, I added a new host template and 34 hosts today, configuration checks out, cfg file is "seen" by Nagios, but the hosts do not show up on the GUI or in the objects.cache file. I had recently added and removed hosts with no issue.

Stopped the service and deleted retention.dat, status.dat, objects.cache. Started the service and hosts are still missing.

I need to continue to use this version of Nagios for some time yet, but I need to get these hosts in there. What else could/should I be looking at?

Thank you.

First, make sure that your config shows up when you verify. Next, lets make sure you do not have multiple nagios parent processes:

Code: Select all

service nagios stop
ps -aef | grep nagios.cfg
killall nagios
ps -aef | grep nagios.cfg
service nagios start

Hi abrist, thank you for replying.

After stopping nagios, I do not have any nagios processes running - nothing to kill.

when I do a config check, it does see the cfg file (IP phones):

Code: Select all

Processing object config file '/usr/local/nagios/etc/hosts/phones.cfg'...

I get 8 warnings for hosts unrelated hosts with no services and 0 errors.

Are the hosts configured with a a host check?

[MKEbrew]

Here is the template and one host directive:

Code: Select all

define host{
        name                            ip-phones
        event_handler_enabled           1
        flap_detection_enabled          1
        retain_status_information       1
        retain_nonstatus_information    1
        check_period                    24x7
        check_interval                  5
        retry_interval                  1
        check_command                   check-host-alive
        register                        0
}

define host{
        use             ip-phones
        name            4800
        alias           4800
        address         x.x.x.x
        hostgroups      Phones
}

IP hidden, of course.

Can you post the full output of a verify in code wraps?

Can you run a grep of the object and status files?

Code: Select all

grep "4800" /usr/local/nagios/var/objects.cache
grep "4800" /usr/local/nagios/var/status.dat

[MKEbrew]

That's what I was saying before, these hosts are not showing in either of those files.

I did grep them just to be sure - nothing.

Wasn't sure if I should stop nagios and clear spool files or what other things I should look at. The only issue I've had before was the retention data would get weird, so I'd stop nagios, delete the dat file, and start it and all would be good.

Never had hosts just not show before.

I really appreciate your help on this!

Can you zip up the whole "nagios" directory and PM it to any of us (Nagios Support Team)?
