Virtual Infrastructure DB Project

This started life as small script to collect VM info from 5 or 6 vCentre's (that were a mix of v2.5 and v4, and weren't linked together), so that VM's could be easily found without having to search through each one. There are essentially 3 components to it...

1. Data collection scripts (run from a Windows desktop)
   • A daily PowerCLI script that collects data from all vCenters (and updates the database)
   • An intra-day PowerCLI script (say every 15mins) that collects basic cluster status data (and updates the database)
2. MySQL database (run on an Ubuntu VM)
3. PHP front end (delivered by Apache running on same Ubuntu VM)
