– Windows Server 2012 R2 Hyper-V host, VMM 2012 R2. All latest patches are installed.

– Agent is installed on this Hyper-V

– Agent’s status (Windows Computer’s status) looks weird: all monitors are green except all top-level monitors. All top-level monitors (Entity Health, Availability, Configuration, Security and Performance) has a blank circles and the overall ‘Status’ for this computer in Windows Computer view is ‘Not Monitored’.

– In VMM console affected Hyper-V host is not in a maintenance mode and fully operational and healthy


Somehow VMM has ‘forgot’ to take out some classes for this server from maintenance mode.

How to find if you affected by the same issue:

1. Run this script and check if you have objects in a MM with the ScheduledEndTime far in a future or objects in a MM that shouldn’t be in a MM:

Import-Module OperationsManager

New-SCOMManagementGroupConnection -ComputerName MyManagementServerName

$MMList = Get-SCOMMaintenanceMode

foreach ($Entity in $MMList) {

$Object = Get-SCOMClassInstance -ID $Entity.MonitoringObjectId

$LogString = $Object.DisplayName+” is in MM until “+$Entity.ScheduledEndTime

Write-Host $LogString

$Object = $null }

Now you can end maintenance mode for these objects.

For ALL objects:

$time = (Get-date).AddMinutes(10)

Get-SCOMMaintenanceMode | Set-SCOMMaintenanceMode -EndTime $time

or for a specific object:

$instance = Get-SCOMClassInstance -Id Your-Object’s-GUID

Get-SCOMMaintenanceMode -Instance $instance | Set-SCOMMaintenanceMode -EndTime $time

Wait for a 10 minutes and the alert should be closed.
