(Something which can be used as a starting point to improve stuff, and I have to write documentation anyhow)
I currently have 3 sources , and one target, which will eventually expand to at least another target and most probably more sources too.
The 3 sources are basically typical system data which I collect using collectd, However I`m using collectd-carbon from https://github.com/indygreg/collectd-carbon.git to send data to Graphite.
I`m parsing the Apache and Tomcat logfiles with logster , currently sending them only to Graphite, but logster has an option to send them to Ganglia too.
And I`m using JMXTrans to collect JMX data from Java apps that have this data exposed and send it to Graphite. (JMXTrans also comes with a Ganglia target option)
Rather than going in depth over the config it's probably easier to point to a Vagrant box I build https://github.com/KrisBuytaert/vagrant-graphite which brings up a machine that does pretty much all of this on localhost.
Obviously it's still a work in progress and lots of classes will need to be parametrized and cleaned up. But it's a working setup, and not just on my machine ..
