############################# INFORMATION #######################################
# VMWare Capacity & Performance Report
# Marc Vincent Davoli (Find me on LinkedIn! http://ca.linkedin.com/in/marcvincentdavoli/)
# PREREQUISITES for this script: Powershell V2, PowerCLI 5.0, Microsoft Chart Controls for .NET Framework (download from this link:
# http://www.microsoft.com/en-us/download/details.aspx?id=14422)
# INPUT for this script: vCenter server IP/hostname, vCenter server credentials, SMTP server IP/hostname
# OUTPUT for this script: E-mailed Report, Report.HTML and Attachments, 1 for each chart (in the working directory)
# Notice 1 : CPU and Memory provisioning potential is calculated by removing 1 host
# Notice 2 : Datastore space provisioning potential is calculated by removing removing 5%
############################# CHANGELOG #######################################
# February 2013 First version
# April 2013 Bugfixes, Added Per Cluster report
# July 2013 Bugfixes, Added Cluster Resilience & Provisionning Potential reports, other minor code adjustements
# January 2014 Added Consolidation ratio, ESXi Hardware & Software Information table, vCenter version, Print Computer name and script version
# May 2015 Fixed issue with Cluster charts not appearing in e-mail report, cause by a space in the cluster name
