Configuration error after upgrade to 2.7

It's referencing a Host that no longer exists:
Code: Select all
Error: Could not find any host matching 'KSKE4165387' (config file '/usr/local/nagios/etc/services/KSKE4165387.cfg', starting on line 93)
Error: Failed to expand host list 'KSKE4165387' for service 'Uptime' (/usr/local/nagios/etc/services/KSKE4165387.cfg:93)
Any ideas?
I'm able to manually Delete, Write, then verify the config & restart Nagios on the Write Config Files (in that order).
So not sure what the issue is. Could this guy be ghosting around somewhere? Went onto the server and looked in usr/local/nagios/etc/hosts directory and not seeing that host at all either.

Well, I doubt you will find an associated host as that is the error. Do you have any files in /usr/local/nagios/etc/static pertaining to this service?
Could you post the contents of:
Code: Select all
/usr/local/nagios/etc/services/KSKE4165387.cfg

In addition to abrist's post, please post the output of the commands below:
Code: Select all
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

Nothing in our static directory:
Code: Select all
[root@esu2v239 services]# cd /usr/local/nagios/etc/static
[root@esu2v239 static]# ls
xiobjects.cfg xitemplates.cfg xitest.cfg
[root@esu2v239 static]#
That's the kicker, we have all our services inherited via Host groups. At one time it probably had a service inherited from one.
We only have this in our services folder:
Code: Select all
[root@esu2v239 nagiosxi]# cd /usr/local/nagios/etc/services
[root@esu2v239 services]# ls
11.24.5.6.cfg Agent Drive C: Disk Usage.cfg Agent Uptime.cfg localhost.cfg
Agent CPU Usage.cfg Agent Memory Usage.cfg esu2v733.federated.fds.cfg Ping.cfg
[root@esu2v239 services]#

That's really weird.
What works and what doesn't?
Apply config from web interface - doesn't work?
Delete, Write, Verify Restart - works?
reconfigure_nagios.sh - works?
Where is it you're actually seeing the error? I guess that's what has me most baffled. I'm assuming somewhere at some command line since you code-wrapped it, but it's not in reconfigure_nagios.sh

Only the Web UI is erroring, which is what we use the most:

Meanwhile the UI gives me:

This is happening on every server I upgrade from 2.5 btw, (ghosting of an old device or service) it happened when I tried to go to 2.6 and I ended up just rolling back and not upgrading because I've had too much to do to deal with it. But would definitely be nice to get this figured out. It's like something in the UI's apply config gets brought back from the dead after the upgrade but doesn't exist anymore and it just thinks it does :/

My theory, and this is just a guess, is that you've got a host entry in the MySQL database that doesn't belong there. I say this because Nagios XI is primary a GUI front end over Nagios core. This is implemented through the addition of PostgreSQL and MySQL backend databases. The GUI makes it so much easier to manage the configuration in a addition to providing additional tools.
I have actually seen errors just like this before, but my memory is awful and I can't tell you the precise circumstances. However, whenever you encounter something where the GUI isn't working, but command line is, I check the backend databases.
You might also try running the following:
Code: Select all
cd /usr/local/nagios/nagiosxi/scripts
./nagiosql_delete_host.php --host=KSKE4165387
If this has no effect, then search the MySQL nagiosql database for the host. If you find it, you may have to perform "surgery" to remove it, which can be very tricky.

Yeah didn't find it, I ran the script from
/usr/local/nagiosxi/scripts as there wasn't a Nagiosxi folder in the nagios sub. Guessin that was a typo:
[root@esu2v239 scripts]# ./nagiosql_delete_host.php --host=KSKE4165387
URL:
http://localhost/nagiosxi/includes/components/ccm/
Unable find host in nagiosql database
[root@esu2v239 scripts]#

JakeHatMacys, "reconfigure.sh" runs fine for you as root. Can you try running it as a nagios user?
Code: Select all
su nagios
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh
Do you get any errors?

Not yet, asking for a a PW when running as "nagios" Is there a standard default? I don't recall ever changing anything regarding it.
