Configure managed availability overrides

 

Applies to: Exchange Online, Exchange Server 2013, Exchange Server 2013 SP1

Topic Last Modified: 2015-11-30

Managed availability performs continuous probing to detect possible problems with Exchange components or their dependencies, and it performs recovery actions to make sure the end user experience is not impacted due to a problem with any of these components. However, there may be scenarios where the out-of-box settings may not be suitable for your environment. Managed availability probes, monitors and responders can be customized by creating an override.

There are two types of overrides: local and global. As their names imply, a local override is available only on the server on which it is created, and a global override is used to apply an override to multiple servers. Both types of override can be created for a specific duration or for a specific version of Exchange, but not both at the same time.

NoteNote:
When you create an override, it doesn't take effect immediately. The Microsoft Exchange Health Management service checks for configuration changes every 10 minutes and loads any detected configuration changes. If you don't want to wait, you can restart the service.

For additional management tasks related to managed availability, see Manage health sets and server health.

  • Estimated time to complete each procedure: 5 minutes

  • You can only use the Shell to perform this procedure. To learn how to open the Shell in your on-premises Exchange organization, see Open the Shell.

To create a local override for a specific duration, use the following syntax.

Add-ServerMonitoringOverride -Server <ServerName> -Identity <HealthSetName>\<MonitoringItemName>[\<TargetResource>] -ItemType <Probe | Monitor | Responder | Maintenance> -PropertyName <PropertyName> -PropertyValue <Value> -Duration <dd.hh:mm:ss>

To create a local override for a specific version of Exchange, use the following syntax.

Add-ServerMonitoringOverride -Server <ServerName> -Identity <HealthSetName>\<MonitoringItemName>[\<TargetResource>] -ItemType <Probe | Monitor | Responder | Maintenance> -PropertyName <PropertyName> -PropertyValue <Value> -Version <15.01.xxxx.xxx>
NoteNote:
When you create the override, the values used in the Identity parameter are case-sensitive.

This example adds a local override that disables the responder ActiveDirectoryConnectivityConfigDCServerReboot on the server named EXCH03 for 20 days.

Add-ServerMonitoringOverride -Server EXCH03 -Identity "AD\ActiveDirectoryConnectivityConfigDCServerReboot" -ItemType Responder -PropertyName Enabled -PropertyValue 0 -Duration 20.00:00:00

To verify that you have successfully created a local override, use the Get-ServerMonitoringOverride cmdlet to view the list of local overrides:

Get-ServerMonitoringOverride  -Server <ServerIdentity> | Format-List

The override should appear in the list.

To remove a local override, use the following syntax.

Remove-ServerMonitoringOverride -Server <ServerName> -Identity <HealthSetName>\<MonitoringItemName>[\<TargetResource>] -ItemType <ExistingItemTypeValue> -PropertyName <PropertytoRemove>

This example removes the existing local override of the ActiveDirectoryConnectivityConfigDCServerReboot responder in the Exchange health set from server EXCH01.

Remove-ServerMonitoringOverride -Server EXCH01 -Identity Exchange\ActiveDirectoryConnectivityConfigDCServerReboot -ItemType Responder -PropertyName Enabled

To verify that you have successfully removed a local override, use the Get-ServerMonitoringOverride cmdlet to view the list of local overrides:

Get-ServerMonitoringOverride  -Server <ServerIdentity> | Format-List

The removed override should not appear in the list.

To create a global override for a specific duration, use the following syntax.

Add-GlobalMonitoringOverride -Identity <HealthSetName>\<MonitoringItemName>[\<TargetResource>] -ItemType <Probe | Monitor | Responder | Maintenance> -PropertyName <PropertytoOverride> -PropertyValue <NewPropertyValue> -Duration <dd.hh:mm:ss>

To create a global override for a specific version of Exchange, use the following syntax.

Add-GlobalMonitoringOverride -Identity <HealthSetName>\<MonitoringItemName>[\<TargetResource>] -ItemType <Probe | Monitor | Responder | Maintenance> -PropertyName <PropertytoOverride> -PropertyValue <NewPropertyValue> -ApplyVersion <15.01.xxxx.xxx>
NoteNote:
When you create the override, the values used in the Identity parameter are case-sensitive.

This example adds a global override that disables the OnPremisesInboundProxy probe for 30 days.

Add-GlobalMonitoringOverride -Identity "FrontendTransport\OnPremisesInboundProxy" -ItemType Probe -PropertyName Enabled -PropertyValue 0 -Duration 30.00:00:00

This example adds a global override that disables the StorageLogicalDriveSpaceEscalate responder for all servers running Exchange version 15.01.0225.042.

Add-GlobalMonitoringOverride -Identity "MailboxSpace\StorageLogicalDriveSpaceEscalate" -PropertyName Enabled -PropertyValue 0 -ItemType Responder -ApplyVersion "15.01.0225.042"

To verify that you have successfully created a global override, use the Get-GlobalMonitoringOverride cmdlet to view the list of global overrides:

Get-GlobalMonitoringOverride

The override should appear in the list.

To remove a global override, use the following syntax.

Remove-GlobalMonitoringOverride -Identity <HealthSetName>\<MonitoringItemName>[\<TargetResource>] -ItemType <ExistingItemTypeValue> -PropertyName <OverriddenProperty>

This example removes the existing global override of the ExtensionAttributes property of the OnPremisesInboundProxy probe in the FrontEndTransport health set.

Remove-GlobalMonitoringOverride -Identity FrontEndTransport\OnPremisesInboundProxy -ItemType Probe -PropertyName ExtensionAttributes

To verify that you have successfully removed a global override, use the Get-GlobalMonitoringOverride cmdlet to view the list of global overrides:

Get-GlobalMonitoringOverride

The removed override should not appear in the list.
