 Added CPU usage graphing to assist with capacity planning. Calculates and graphs an "Effective Number of VCPUs Utilised". Added CPU usage graphing to assist with capacity planning. Calculates and graphs an "Effective Number of VCPUs Utilised".
 +
 +Recently added a feature to alert if the SP-Config was not up to date. For those who don't know, this is the virtualisation config, which needs to be updated after changes. Forget and reboot, and it loads the previous config, potentially with disasterous results. It's nice to be reminded to update it if required.
