Comments on: Dynamic Computer groups that send heartbeat alerts

Hiya,

I’ve managed to create a dynamic group and was wondering if anyone could assist with the code I’d need to add to send alerts if any machines in the group I’ve created go offline ?
I’ve manually added the machines I want to have monitored using “Explicit Machines” and “Dynamic” using thier IP addresses. I’m not sure that the “Health Monitor” is the agent I want to use – or if I should be using the “Ping Target” one ? Also as there are four classes for Ping – watcher, target, target role and utilities – Is “Ping Target” the right one ?

Thanks in advance for any answers – first time I’ve been introduced to SCOM2007 so a little bewildered with it all !!

I am trying to make a dynamic group based on multiple Active directory OU’s with the health watcher. I cannot import the MP. I get the following error The requested management pack was invalid. See inner exception for details. Parameter name: managementPack This is the XML Code. ESD.OU.Tesst.Two 1.0.0.2 ESD OU Tesst Two Microsoft.Windows.Library 6.1.7221.0 31bf3856ad364e35 Microsoft.SystemCenter.InstanceGroup.Library 6.1.7221.0 31bf3856ad364e35 Microsoft.SystemCenter.Library 6.1.7221.0 31bf3856ad364e35 Discovery $MPElement$ $MPElement[Name="UINameSpace462c1be2b85a4317945ad6c376af77f2.Group"]$ $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]$ $MPElement[Name="MicrosoftSystemCenterInstanceGroupLibrary6172210!Microsoft.SystemCenter.InstanceGroupContainsEntities"]$ $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]/OrganizationalUnit$ ContainsSubstring SEA $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]/OrganizationalUnit$ ContainsSubstring BEL $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]/OrganizationalUnit$ ContainsSubstring AUB $MPElement[Name="SystemCenter!Microsoft.SystemCenter.HealthServiceWatcher"]$ $MPElement[Name="MicrosoftSystemCenterInstanceGroupLibrary6062780!Microsoft.SystemCenter.InstanceGroupContainsEntities"]$ $MPElement[Name="SystemCenter!Microsoft.SystemCenter.HealthService"]$ $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]$ $Target/Id$ ESD OU Tesst Two Test with more that one ou.

Looks like my previous post did not inlcude all the XML tags. If you visit the following link and go to my last post you can find the complete code.

Ok I was able to take this logic and apply it to add cluster objects as well. Here is my code. $MPElement[Name="Windows1!Microsoft.Windows.Cluster.Component"]$ $MPElement[Name="MicrosoftSystemCenterInstanceGroupLibrary6172210!Microsoft.SystemCenter.InstanceGroupContainsEntities"]$ $MPElement[Name="Windows1!Microsoft.Windows.Cluster.HostedGroup"]$ $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]$ $Target/Id$

I posted a question to the MS forums regarding a problem I am having with this XML code in case anyone has any feedback. Much appreciated!

Jason is write for R2 users! You will have to change your MP Element attribute #’s. You can verify what the number should be if you look at the dynamic rule you created for the group in SCOM before you exported it. Make sure you update it accordingly from the watchers.xml code here.

For R2 it is:

6172210

Thanks Jason and whoever authored the original solution. Very very helpful!

@ Seth and Francisco:
I had the same problems and solved this issue. The tip from rory is not bad. You have to change only a little part but not in the reference section. You have to change the following in the health service section:

original:
$MPElement[Name="MicrosoftWindowsLibrary6062780!Microsoft.Windows.Computer"]$

changed:
$MPElement[Name="MicrosoftWindowsLibrary606278100!Microsoft.Windows.Computer"]$

than the Health service watcher is included in your dynamical group.

What about False Positives? I’ve been getting alot of false positives, when really, I’m more concerned with being alerted that the Server is actually offline.

I know that the Health Service Heartbeat Failure and the Computer not Pingable work alongside each other. Is there a way to just get the “Computer Not Pingable” alert, and not the “Health service heartbeat Failure” alert?
