vim = RbVmomi::VIM.connect host: vcenter.hostname, user: vcenter.username, password: vcenter.password, insecure: true
pm = vim.serviceInstance.content.perfManager
# this is for a single cluster with hosts directly in one cluster. 'first' returns the cluster object.
hosts = vim.serviceInstance.find_datacenter.hostFolder.children.first.host
pm.retrieve_stats([hosts[0]], ['cpu.usagemhz'], {interval: '300', start_time: (Time.now - 6.hours)}).first[1][:metrics]['cpu.usagemhz']
# This above query queries for the 'cpu.usagemhz' counter, which by default matches the (none) rollup counter (NOT THE AVERAGE) in vSphere API.
# This is a problem with the RbVmomi gem helper function "retrieve_stats" only. To override this, use the following manual counter selection:
