On the node machine you can test if a munin plugin is working with a command like this:

munin-run apache_processes

This should spit out the same data that munin receives every 5 minutes to plot the graph.

Right now I'm trying to work out why I'm getting nothing but 'U' values from the apache_processes munin plugin, resulting in an empty graph. Any suggestions?

I just had a second go at getting Nginx working and found a new nginx_combined plugin:

http://exchange.munin-monitoring.org/plugins/nginx-combined/details

Usage information is in the Perl file. Throw the file in the plugins folder og symlink the combined plugin in as nginx_combined_[hostname]

Remember to set up stub_status on the same host as specified in the symlink.

Looks good, but you need to reverse the linking steps - you need the nginx_status in the directory when you run perl autoconf.

So, it should be like this:

cd /usr/share/munin/plugins/ perl nginx_request autoconf

cd /etc/munin/plugins/ sudo ln -s /usr/share/munin/plugins/nginx_request nginx_request sudo ln -s /usr/share/munin/plugins/nginx_status nginx_status

Thanks for the documentation! Munin tutorials are pretty sparse. Were you able to get Nginx monitoring working?
