No time for a long writeup (but I assure you this will be covered in great detail in my book!) but the code and screenshots should explain very well:
Code:
1: Process {
2: $HostView = Get-View $_.Id
3: $Process = "" | Select-Object VMHostName, OverallStatus, OverallCpuUsage, OverallMemoryUsage
4: $Process.VMHostName = $_.Name
5: $Process.OverallStatus = $HostView.Summary.OverallStatus
6: $Process.OverallCpuUsage = $HostView.Summary.Quickstats.OverallCpuUsage
7: $Process.OverallMemoryUsage = $HostView.Summary.Quickstats.OverallMemoryUsage
8: Write-Output $Process
9: }
Attachment: get-hosthealth.ps1
Output:
PS > Get-VMHost | scripts:\book\Get-HostHealth.PS1 VMHostName OverallStatus OverallCpuUsage OverallMemoryUsage ---------- ------------- --------------- ------------------ 192.168.0.51 green 336 1070 192.168.0.55 green 24 417
And even cooler, with PowerGadgets:
