+The problem I was trying to solve was that I wanted to monitor the vitals of all my VM's without having to install collectd into each VM, by talking to vCenter we can pull everything out that we need.  This work was inspired by [[https://github.com/llambiel/collectd-vcenter|collectd-vcenter]] which I could not get to work as its assumes you have an ESX Cluster.  So I wrote my own.
