Nagios Support Forum

Hi Y'all,

After updating from 5.5.8 to 5.5.9, I noticed that several websites that we're monitoring suddenly started monitoring for CPU and Memory information. None of the services appeared in services under CCM and do not appear/usr/local/nagios/etc/services .cfg files.

I restarted nagios and the ndo2db server hoping that it would resolve the issue. Using systemctl restart nagios and systemctl restart ndo2db which did nothing. After doing so research i found files were in the following directory /usr/local/nagios/share/perfdata which holds temporary files used for graphic performance data from services. After removing the services from that directory, i noted that the services were still showing up in the GUI. After restarting nagios, i then noticed that those same files that i removed from perfdata started to appear again.

Now, here is where things get weird. We're having the same issue with one of the routers that we monitor. We only ping the routers because we use another monitoring tool for our routers. This host also has CPU and Memory monitoring but they do not show up under perfdata/router-colo/ directory. on top of that, there is nothing in the /usr/local/nagios/etc/services .cfg filethat says is supposed to monitor for those services.

Im at a complete loss here.

If I had to guess, these website hosts are members of a hostgroup.

Someone added this hostgroup to one of the "CPU Usage" and services being "Memory Usage" services being monitored

Hi scottwilkerson,

I tried that and it didnt work. Now, the ghost services are no longer there.

It didn't work but the ghost services are no longer there?

Is there any remaining issue?

The ghost services just stopped showing up. I guess we can close this, ill just open up a new issue should it happen again.
