What if I dont want to put the whole computer into maintenance mode?

  • Artikel

Sometimes you may not wish to put the whole computer into maintenance mode. Instead you may wish to put just a number of databases or websites into maintenance mode.

The steps are very simple:

1 - Get the monitoring class that represents the type of monitoring objects that you wish to put into maintenance mode

2 - Get the actual monitoring objects

3 - Iterate through the array of monitoring objects and put them into maintenance mode (dont forget to check whether you got a single monitoring object or an array, this is pretty important) 

Here is a sample of how to do this using PowerShell:

$sql2005DBClass = get-monitoringclass | where {$_.DisplayName -eq 'SQL 2005 DB'}

$dbInstances = get-monitoringobject -monitoringclass:$sql2005DBClass | where {$_.Name -match 'TestDB'}

$startTime = [DateTime]::Now

$endTime = $startTime.AddHours(2)

if($dbInstances -is [Array])
{
foreach($dbInstance in $dbInstances)
{
 New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -reason:'PlannedHardwareMaintenance' -monitoringobject:$dbInstance -comment:'comment goes here'
}
}
else
{
 New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -reason:'PlannedHardwareMaintenance' -monitoringobject:$dbInstances -comment:'comment goes here'
}

This script will find all databases where the DB name is like TestDB and then put then into maintenance mode for two hours.

    Very good,If you have 2 instances of TestDB, and of course you just want to put only 1 in maintenance mode, how is it possible ? How to add the computer information in that case to make the difference ?Thanks for your very useful blog...

    Here is how you can do this:function GetHostingComputerObject ($monitoringObject){$hostingRel = Get-RelationshipClass -name:'System.Hosting'$computerClass = Get-MonitoringClass -name:"Microsoft.Windows.Computer"$relatedObjects = $monitoringObject.GetMonitoringRelationshipObjectsWhereTarget($hostingRel,[Microsoft.EnterpriseManagement.Configuration.DerivedClassTraversalDepth]::Recursive,[Microsoft.EnterpriseManagement.Common.TraversalDepth]::Recursive) | Select-Object SourceMonitoringObject$hostingComputerInstance = $nullforeach($object in $relatedObjects){$classIds = [Array]$object.SourceMonitoringObject.MonitoringClassIdsforeach($classId in $classIds){if($classId.ToString() -eq $computerClass.Id.ToString()){$hostingComputerInstance = $object.SourceMonitoringObjectbreak;}}}$hostingComputerInstance}$sql2005DBClass = get-monitoringclass | where {$.DisplayName -eq 'SQL 2005 DB'}$dbInstances = get-monitoringobject -monitoringclass:$sql2005DBClass | where {$.Name -match 'TestDB'}$startTime = [DateTime]::Now$endTime = $startTime.AddHours(2)if($dbInstances -is [Array]){foreach($dbInstance in $dbInstances){$computerObject = GetHostingComputerObject $dbInstanceif($computerObject.DisplayName -eq 'dbsrv1.contoso.com'){New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -reason:'PlannedHardwareMaintenance' -monitoringobject:$dbInstance -comment:'comment goes here'}}}else{$computerObject = GetHostingComputerObject $dbInstancesif($computerObject.DisplayName -eq 'dbsrv1.Contoso.com'){New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -reason:'PlannedHardwareMaintenance' -monitoringobject:$dbInstances -comment:'comment goes here'}}Basically I added a function that returns the computer which hosts the DB. Then you can check the computer name and decide if you want to put the DB into maintenance mode or not.

    Is it possible to put specific monitors that make up an object into maintenance mode?  The situation I have is that we are monitoring several WSS 3.0 servers. On 2 of them, the Timer service is disabled due to a bug.  The SharePoint administrators don't want to monitor the timer service on these servers for the next 2 weeks while they are troubleshooting and testing to resolve the problem.

    Unfortunately you cannot put a single monitor into maintenance mode. What you can do for the next two weeks is disable the monitor using an override.
