vmware historical reporting

If you do not have vCenter and you want to be able to collect performance stats past 1 hour, this option is greyed out in the vSphere client, however turning this on is pretty easy:

1. SSH to the host
2. Open the file “vi /etc/vmware/hostd/config.xml”
3. Find the <historicalStatsEnabled> tag under <statssvc> and make this true
4. Run “services.sh restart”
