Duplicate entries in nagios xi

[Naveed]

Team,

Few services in my nagios xi are showing duplicate services.

I have checked the required files but I can see that every service is defined only once.

I have just replace notification group in a one file with following command, after that 4-5 servers are showing duplicate entries.

I have attached screenshot for verification.

Need your suggestions to take care this.

Thank you!

By any chance are there multiple Nagios processes running?
What does the output of ps -aef | grep nagios.cfg reveal?

If there are multiple nagios.cfg, then run these commands and let us know of the outcome:

Code: Select all

service nagios stop
killall -9 nagios
service nagios start

Thank you for your reply.

[root@]# ps -aef | grep nagios.cfg
nagios 53656 1 1 15:45 ? 00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
nagios 53668 53656 0 15:45 ? 00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
root 53716 52917 0 15:45 pts/0 00:00:00 grep --color=auto nagios.cfg

I killed both processes and start nagios server. But still I can see that duplicate entries still exist.


I ran following command, do I need to kill all these processes as well?

Code: Select all

nagios 55225 1 0 15:48 ? 00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
nagios 55238 55225 0 15:48 ? 00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

You can see the second entry (55238) is a child of the first entry (55225), this is normal expected behaviour. There would be a concern if there were separate master instances of nagios running.

Looking at your screenshot:


It actually looks like Nagios is working correctly and those services exist in your configuration files. The reason I say this is because:
Check CPU load
Check CPU Load
and
check drive status
Check Drive status

Use different uppercase / lowercase characters and are different.

All you need to do is delete the services in CCM that you don't want.

[Naveed]

Good point my dear.

But these duplicate services do not show in CCM, and also in nagios configuration files. I have already checked it, but nothing worked for me.

Further adding to this, as I delete one of my original service check CPU load, after restart all CPU Load services also disappear.

please suggest a solution.

Thank you

[Box293]

Please execute these two commands:

Code: Select all

grep -R -l 'Check CPU load' /usr/local/nagios/etc/
grep -R -l 'Check CPU Load' /usr/local/nagios/etc/

The results should be the name of the files those configs exist in.

Please post the config files here.

[Naveed]

Thank you!

I have attached 3 config files for review.
Kindly see and help me out.

Thank you!

I believe this is related to your current issue of the ghost services here at this point - https://support.nagios.com/forum/viewto ... 93#p187993

If not, please post your entire objects.cache file for us to look at - [/icode]/usr/local/nagios/var/objects.cache[/icode]. This will help us to see how your configurations are all compiled together, it could be a group.

[Naveed]

Hello,

I have attached required file to take a look into it.

Thank you!

I suspect you have multiple services defined for some hosts, some are lowercase while some are not as you can see here you have two for uptime -

Code: Select all
