Problems with XI displaying 4x duplicate services and hosts

Posted: Thu Sep 27, 2012 3:58 pm

ever since the upgrade to 2011R3.3, nagiosXI shows each service and host 4 times. Occasionally after an apply configuration it goes back to normal, but it has consistently done this since the upgrade. naigos core does NOT do this. viewing the operational files, the status.dat, retentionl.dat, etc are all what you would expect - no duplicates.

ideas?

For all support requests, we need to know:
CentOS release 5.8 (Final)
32 or 64bit? 64 bit
VMware Image or Manual Install of XI? Manual
no Gnome, no proxy, no ssl.

is there anything you're looking at? This production monitoring system is doing a bunch of tasks. for instance...a tail of the message file will get you lots of non-applicable stuff. Regardless...here is a tail of /var/log/messages.

Try running the following:

Code: Select all

service nagios stop
killall -9 nagios
service ndo2db stop
service ndo2db start
service nagios start

We've been living with this for quite a while now. Here is some additional information:
1) Services, not hosts duplicate 4x
2) this only happens when an "apply configuration" is performed
3) when you killall -9 nagios the service restart, the XI counters are correct
4) nagios core (/nagios) is not affected by this
5) notifications are not affected
6) retention and status files do not have 4x entries

this seems to be a XI ui issue only. Any assistance would be appreciated.
we have upgraded since this started happening:

After you apply configuration and these duplicates appear how long does it take before they..disappear? Can you provide a screenshot of this as it happens? I'm also curious to see how many processes are running when this happens. Next time it does can you run the following command and post the output with the screenshot of your UI?:

Code: Select all

ps -ef|grep bin/nagios | grep -v grep
Also, how many checks is your system running on average per minute? And what is the load on the system.

nagios core information.png
after applying the configuration, duplicates happen as soon as XI starts displaying status again. these ghost services will only go away by killing the nagios processes and restarting. (killall -9 nagios; service nagios restart).
this is very easy to duplicate - it is just a matter of applying the configuration. Again - nagios core is unaffected, so these ghost host and
nagios core information.png
services must only be present in the XI ui.


Attached is a screenshot of the tactical showing both.


nagios 4589 1 16 16:05 ? 00:00:01 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

FYI: http://<serveraddress>/nagiosxi/backend/?cmd=getservicestatus sometimes times out, depending on the load at the time. I don't know if this is related, or not - it is listed in the troubleshooting steps when the count is incorrect? XI Display Problems.

Do you get any errors or notices in the /usr/local/nagios/var/nagios.log file when you run:

Code: Select all

service nagios restart

Also, lets try the following:

Code: Select all

service nagios stop
rm -f /usr/local/nagios/var/retention.dat
service nagios start
This will start nagios with everything in a pending state, but should give somewhat of a clean reset.

Can you also post your /usr/local/nagios/etc/nagios.cfg file?

Can you run the DB repair procedure? Lets make sure there's not any DB corruption so we can rule that out.
