I have a server that is not showing up in the Graph Explorer. I'm 100 % sure it was there a month ago. I think it has something to do with the 2.8 update probably. I noticed it today as I was cleaning up a dashboard. After deleting a dashlet for this particular server, I wanted to re-add it, but it seems to be no longer in the host list where you select hosts in the Graph Explorer.
When I go the server through quick find, the server is still there and I can access it's perfdata form the last 24 hours with the new graph icon. When I go to /usr/local/nagios/share/perfdata I can see the rrd and xml files.
That is very interesting, could you "tail -f /var/log/httpd/error_log" and visit that page please?

The reason for that is that the name of the server is also a web application. In fact I added the web application like 6 months ago and about two months ago, the server needed to be monitored too. So I added the default cpu, drive etc services to the web application. Why would this be an issue for a host to show up in graph Explorer?

Host checks will save their performance data to __HOST__.rrd. If you are missing this file, you may not have any checks configured for the host. Does the host that this service runs under have a host-check configured?
