Hello,
In regards to Capacity Planning for ESXi 5.x, I have seen various examples on capturing capacity utilizations for CPU, Memory, Number of ESXi Hosts, Number VMs, etc. at the Cluster level, and I’d like to execute this in one PowerCLI Script and exported to one .CSV file. I don’t need Datastore statistics.
On JONATHAN MEDD'S BLOG, the URI below is great, however I’d like to have more control; add number of Hosts and VMs for the Cluster(s) I specify, and exported to a .CSV file.

Thank you!

Below is what I’m trying to accomplish (.PS1 has also been attached):
