Nagios Support Forum

I have one Nagios XI server that has a blank service check.I have 82 services in CCM, but when I look at the service status summary dashlet, it lists 83 total services. When clicking on the 83, I see one service that has no name, no host and some nonsense in the date and last check fields. I have looked through my configuration files in /usr/local/nagios/etc/services/ and I see no files with a blank host and blank service description. I see no unusual services configuration files either. How to I find and remove this service?
I am running Nagios XI 5.5.3 on Red Hat 7 64bit.

Hello, @hbouma. This could be a corrupted entry in the database. I suggest running a repair_db script first to see if the problem goes away:

/usr/local/nagiosxi/scripts/repair_databases.sh

That was run, unfortunately, the phantom service is still there.

@hbouma, Please upload the following file:

/usr/local/nagios/var/objects.cache

And then run this query:

echo "SELECT * FROM nagios_services\G;" | mysql -uroot -pnagiosxi nagios > /tmp/nagios.txt

It will generate nagios.txt file in the /tmp/ directory. Please upload that file here as well.

I can tell you already that the object.cache file has some outdated information in it.

@hbouma, Thank you. Please run the following commands in order and let me know if the issue gets resolved:

service nagios stop
rm /usr/local/nagios/var/objects.cache
rm /usr/local/nagios/var/status.dat
rm /usr/local/nagios/var/retention.dat
service nagios start

Unfortunately, this didn't work.

However, the file /usr/local/nagios/var/status.dat doesn't exist. Could that be why the problem didn't disappear?

@hbouma, No that's normal. It is supposed to get automatically deleted every time Nagios service stops. But sometimes it doesn't and that's why I included that command.
