PowerShell can be useful for many things.
There are PowerShell Cmdlets that make it fairly simple to examine the amount of memory used by processes or virtual machines.
Examples:
Sum of working set for all processes:
Get-Process | Measure-Object WorkingSet -Sum
"{0:N2} GB" -f ((Get-Process |
Measure-Object WorkingSet -Sum).sum / 1GB)
Sum of assigned memory for Hyper-V virtual machines:
Get-VM | Select-Object MemoryAssigned | Measure-Object MemoryAssigned -Sum
"{0:N2} GB" -f ((Get-VM |
Select-Object MemoryAssigned |
Measure-Object MemoryAssigned -Sum).sum / 1GB)
Sorted list of processes with working set in megabytes:
Get-Process |
Select-Object Name,@{Name='WorkingSet';Expression={($_.WorkingSet / 1MB)}} |
Sort-Object -Property WorkingSet
