Hello,
Getting detailed vFRC statistics requires esxcli and is not easy for handling many instances.
So I wrote a simple PowerCLI script supports retrieving vFRC stats from multiple ESXi hosts and .vmdk's easily.
This script can also provide ps_vcops_httpost.ps1(https://community.emc.com/message/568368#568368)
compatible data for you who want to monitor vFRC stats using vC Ops.
Please refer to Cmdlet help for usages.
Thank you,
Ho-Sung.
