Replying to jim:
I started work on adding MySQL and NGINX reporting to collectd... The latter works, but while I put the stub in for the for MySQL monitoring in /etc/collectd/collectd.conf, I never got to finishing the setup in MySQL as Chris decided to go with Munin.
The advantage with munin is the the plugins are easy to hack on, they are generally written in perl and bash, with collectd they are written in C, as mentioned in ticket:470#comment:41
Regarding collectd it looks like generating stats from things like php-fpm would need some work, but there is a example of how to do it. Personally I think we should probably stick with Munin for now.
Suggest we uninstall collectd -- I've already taken it out of .barracuda.cnf... changing title & desc.
OK:
dpkg -r collectd-core collectd

I've just commented out the lines (around 414) in the above file, and restarted collectd.
