I have been working on this for a few hours now, and haven't yet been able to get munin to output the html files/generated graphs of resource usage on my CentOS 5.3 server.
Here are some things I run as the munin user, and the results:
/usr/share/munin/munin-update --nofork --debug
(above works fine, takes ~2.4 seconds to complete)
(And other options/plugins (besides 'cpu'), all work fine and give desired output)
[FATAL] There is nothing to do here, since there are no nodes with any plugins. Please refer to http://munin-monitoring.org/wiki/FAQ_no_graphs at /usr/share/munin/munin-html line 38
I am wondering if, perhaps, the settings in my munin.conf file might be causing a problem. Here's the contents of that file (below):
bdir /var/lib/munin/ htmldir /home/archdev/public_html/monitoring logdir /var/log/munin rundir /var/run/munin/ tmpldir /etc/munin/templates [archstl.archstl.org] address 127.0.0.1 use_node_name yes
Also, when I run the telnet localhost 4949 command, and list the node's plugins, it returns the default munin list... something seems to be wrong with the munin html creation process. :(
I'm running version 1.4.3.
