Active host & service checks and notifications are disabled

Hi,
I'm trying to test some stuff we're planning on doing, on a separate instance of our main subscribed NagiosXI server, prior to deploying on the live server, but I've come across a problem.
There was a plain Nagios Core installed before I installed XI, so I did "yum -y remove nagios" before the XI install, then after XI installed (xi-2012r2.3), I imported the configs from the old Core files & I see the old hosts & services when looking at the CCM, but I do not see anything in the status.php & the system status indicators are showing green, green, green, blue, blue, blue - meaning: -
* Monitoring Engine Is Running
* Performance Grapher Is Running
* Database Backend Is Running
* Active Host Checks Are Disabled
* Active Service Checks Are Disabled
* Notifications Are Disabled
If I click on the blue icons, I see a red one for the process state, even though the process is running.
I Googled and searched this forum, but the only thing I found was
this but the values are pre-configured on my system & the problem doesn't go away after 5-6 mins.
What have I done wrong or missed (it's bound to be something daft)?

Are you able to enable host and service checks via the admin->Monitoring System Status page? If not, what is the process state there?

When I press the "Play" icon, this happens in the nagios.log: -
Code: Select all

OK, lets try killing and restarting all the important nagios stuff.
Code: Select all
service ndo2db stop
service nagios stop
killall -9 nagios
ll /usr/local/nagios/var/nagios.lock (This should not exist at this point, remove if it does)
service nagios start
service ndo2db start
Just to check permissions, lets also:

Sorry, bit of premature postage there...
OK, I've done all the restarty stuff (& confirm that the nagios.lock file did not exist when listed). I have also rebooted a couple of times too (before posting here).

Well your permissions look fine, are you still having issues, or did killing and restarting work? I do notice that the ndo2db and nagios lock files have vastly different times on them, if you just restarted both services, those should be within a minute or two of each other.

Just to make sure it's working, run:
chown nagios.nagios /usr/local/nagios/var/nagios.lock
Basically, you are seeing that lock file get created as nagios.users, which apache is not a part of the users group. Within about 30 seconds of the change, you should see the status page show nagios process as up. Then we need to work out why it is being created incorrectly.

No, it's the nagios.log file that is nagios:users nagios.lock is definitely being created with nagios:nagios ownership...

doh, my brain isn't working today. So then, any luck with the webui changes, or is that still a no-g as well?
