Orphaned service alert

[ITOPS_SPOC]

Hello,

Under Home Dashboard -> Service Status Summary -> Critical we are seeing blank service. See scrshot

Please help me how to get ride of this service alert which is orphaned.

Hi Gregor,

That is odd. Let's re-start the Nagios Service.

Code: Select all

systemctl stop nagios.service
killall -9 nagios
systemctl start nagios.service

Then apache.

Code: Select all

systemctl restart httpd

And then try to force an immediate check. Does it update and continue to update?

See: Nagios XI - Last Check Time Not Updating

If the issue persists, send us the system profile and we'll check the nagios and database logs. Thanks, Benjamin

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button

Hi Benjamin,

since we have dedicated server for Nagios I have rebooted server. Orphaned service is still there. I am unable to execute "force an immediate check" since Host and Service field are blank. Nothing to click there.

Uploaded profile file.

Hi Gregor,

The profile looks pretty good, I didn't see any current database errors.

Please go to Configure > Core Config Manager > Tools > Write Config Files
- Click Delete (don't worry, it's safe, they get re-written)
- Click Write
- Now click verify and see if it verifies properly, if it does, try to apply configuration

Then check the GUI once more and let me know if it is still there. If so, please log into the Nagios Core interface and let me know if you see on it on that side (those pages do not use the database).

Code: Select all

httt://<IP address>/nagios

Lastly, we can determine what host that service is part of by searching the archives, go to:

Code: Select all

cd /usr/local/nagios/var/archives

And then do a recursive search for that string in the GUI and let me know the results. Thanks, Benjamin

Code: Select all

grep -iR "----search string here-----"

Hi Benjamin,

deleting config files did not help.

Please run this command and PM me the resulting /tmp/OBJECTSDUMP.sql file:

Code: Select all

mysqldump -uroot -pnagiosxi nagios nagios_objects nagios_servicestatus nagios_hoststatus > /tmp/OBJECTSDUMP.sql

Hi Ssax,
I have sent you PM with output.

Please run this command and it should fix it:

Code: Select all

mysql -uroot -pnagiosxi nagios -e "delete from nagios_servicestatus where service_object_id = '-1';"

Thank you. It worked. This can be closed.
