Schedule a group of URLs into Maintenance Mode

admin

• February 10, 2009 • February 10, 2009

I needed to schedule a group of URLs into Maintenance Mode. I already created a script to schedule one URL but setting up 30 would be a pain to manage. So I created a new script to schedule a group of URLs.

URLGroupMM.zip

Usage:
C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe C:\URLGroupMM.ps1 -rootMS scomrms1 -group ‘AU 3AM Website Reboot Group’ -minutes 120 -comment ‘3AM AU Websites Reboot’ -reason ‘PlannedOther’

param($rootMS,$groupName,$minutes,$comment,$reason)

Add-PSSnapin “Microsoft.EnterpriseManagement.OperationsManager.Client” -ErrorVariable errSnapin;

Set-Location “OperationsManagerMonitoring::” -ErrorVariable errSnapin;

new-managementGroupConnection -ConnectionString:$rootMS -ErrorVariable errSnapin;

set-location $rootMS -ErrorVariable errSnapin;

$groupObject = get-monitoringobject | where {$_.DisplayName -eq $groupName};

$groupagents = $groupObject.getrelatedmonitoringobjects()

foreach ($agent in $groupAgents)

{

$URLStuff = $agent.displayname

$URLStuff

$URLWatcher = (Get-MonitoringClass -name Microsoft.SystemCenter.WebApplication.Perspective) | Get-MonitoringObject | where {$_.DisplayName -eq $URLStuff}

$startTime = [System.DateTime]::Now

$endTime = $startTime.AddMinutes($minutes)

“Putting URL into maintenance mode”

New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -monitoringObject:$URLWatcher -comment:$comment -Reason:$reason

}

Hi Tim,
thank you for sharing this.
There is a mistake at the code:
$groupObject = get-monitoringobject | where {$_.DisplayName -eq “AU 3AM Website Reboot Group”};
The group name should be replaced with the variable “$groupName”

Regards

Matthias

Good eyes. I put that in there to test it and forgot to change it back. I have fixed the zip and the post.

Thanks,

Tim

I tried this URL group maintenance mode powershell script and it doesn’t appear to work.
I am getting the following error:

You cannot call a method on a null-valued expression.
At D:\Temp\URLGroupMM.ps1:9 char:56

Thanks,

  Make sure your group only contains objects of type “Web Applicaiton Perspective”

What object type(s) did you add to the custom group?

Please Assist not sure what is wrong

I am doing the following steps….

Using Web Application Transaction Monitoring
Add monitoring Wizard
Web Application Transaction Monitoring
Give A name and Select a custom mgmt pack
Type the URL http://www.hotmail.com and Click Test
Select a Watch node.

I add another URL using the above method
Url: http://www.google.com

So now i have 2 URL for monitoring

Next i create a custom group called “URL monitoring”
using “Objects of type Web Application Perspective”, i add both the names.

Then i run the powershell command

C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe c:\URLGroupMM.ps1 -rootMS: ‘FhGscomprod’ -GroupName: ‘URL Monitoring’ -minutes:5 -comment: ‘My Comment’ -reason: ‘PlannedOther’

I still get an error….

If you have multiple watcher node for the same URL then script fill fail because multiple objects are being enumerated for that just add another foreach loop. Here is the working one;

param($rootMS,$groupName,$minutes,$comment,$reason)

Add-PSSnapin “Microsoft.EnterpriseManagement.OperationsManager.Client” -ErrorVariable errSnapin;
Set-Location “OperationsManagerMonitoring::” -ErrorVariable errSnapin;
new-managementGroupConnection -ConnectionString:$rootMS -ErrorVariable errSnapin;
set-location $rootMS -ErrorVariable errSnapin;

$groupObject = get-monitoringobject | where {$_.DisplayName -eq $groupName};
$groupagents = $groupObject.getrelatedmonitoringobjects()

foreach ($agent in $groupAgents)
{
$URLStuff = $agent.displayname

$URLStuff

$URLWatcher = (Get-MonitoringClass -name Microsoft.SystemCenter.WebApplication.Perspective) | Get-MonitoringObject | where {$_.DisplayName -eq $URLStuff}

foreach ($eachurl in $URLWatcher)
{

$startTime = [System.DateTime]::Now
$endTime = $startTime.AddMinutes($minutes)

“Putting URL into maintenance mode”

New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -monitoringObject:$eachurl -comment:$comment -Reason:$reason
}
}

Is this applicable to SCOM 2012 as well?

[…] As I have said in SCOM Trick 7, the use of maintenance mode is important. But not always will somebody use the normal SCOM interface (or web interface) to start maintenance mode right before they start working on the machine. To be honest a lot of the times machines get placed in maintenance mode when the alerts start flowing in during planned work and they quickly place the machine into maintenance mode. In any case, you can actually schedule maintenance mode, or include it in scripting. Here are some resources to get you started.
