Nagios Performance graphs



I’ve just installed Nagios XI 2011R1.2 on a fresh CentOS 32 bit server following the guide here: … ctions.pdf

Everything seems to work fine except for the performance graphs. When I click on the “Performance Graphs” for a host it just display the headers - no graphs.
The Nagios server has been logging for a while so there should be data available.

When looking at the host attributes under Host Advanced, it has a green light for the state next to “Performance Data”.

Has anyone experienced this and have any tips on how I can solve this?

Thanks in advance!



I found the cause for this: Had to set the hostname in /etc/hosts.
