Check Memory Waste Levels

You can check the memory waste levels of a virtual machine host for a specific period of time. For example, you can check the memory waste levels in the last month.

Prerequisites

• Verify that you are connected to a VMware Aria Operations instance.
• Verify that you are connected to the vCenter Server system that is monitored by the VMware Aria Operations instance.

Procedure

1. Browse the vCenter Server inventory and select a virtual machine host for which you want to check the memory waste levels.

   $vmHost = Get-VMHost 'MyHost'

2. Get the VMware Aria Operations resource that refers to this virtual machine host.

   $hostResource = $vmHost | Get-OMResource

3. Check the defined metrics for this VMware Aria Operations resource type.

   Get-OMStatKey -AdapterKind $hostResource.AdapterKind -ResourceKind $hostResource.ResourceKind

4. Get data for a specific metric.

   $hostResource | Get-OMStat -Key "mem|waste"

   Note: This command retrieves all available metric data with the highest available granularity.
5. Get metric data for the last month aggregated on a daily basis.

   $hostResource | Get-OMStat -Key "mem|waste" -From ([datetime]::Now.AddMonths(-1)) -IntervalType Days -IntervalCount 1 -RollupType Avg
