Running the query below, showed that this MP is really a data dumper:
SELECT TOP 50 AlertStringName, AlertStringDescription, AlertParams, Name, SUM(1) AS
AlertCount, SUM(RepeatCount+1) AS AlertCountWithRepeatCount
FROM Alertview WITH (NOLOCK)
GROUP BY AlertStringName, AlertParams, Name
ORDER BY AlertCount DESC
You could also use the new report, Data Volume by Management Pack, available through the new SCOM R2 management pack,System Center Core Monitoring, version 6.1.7599.0. (http://www.microsoft.com/downloads/details.aspx?FamilyID=61365290-3c38-4004-b717-e90bb0f6c148&displaylang=en)
I disabled any VM monitoring activities from nWorks, because the VM's were already monitored through a SCOM Agent. This can be configured through the nWorks Management Console. It's just a mather of deselect the checkboxes for VM's. As this screenshot shows:
Disabling discoveries for VM's, or not?
Seeing this, i thought disabling the discovery for any VM based object would do the trick.
So i disabled the discovery 'SV100 first stage discovery' for the class 'nWorks Collector' and the class 'VM'.
Hhm yeah right.
After doing this i lost ALL nWorks discovered objects. It apeared this discovery is linked to all discovered objects and not just the VM/Virtual Machine object. :(
So this is really a NO NO. The 'SV100 first stage discovery' discoveres all objects and relationships.
Deleting and Re-importing the nWorks VMware MP
I decided a reimport would be best.
I made a backup of the customizations Management Pack linked to the nWorks VMware MP and deleted it.
Then i deleted the nWorks VMware MP itself.
And then. Nothing.... Nothing?? Well, deleting this specific Management Pack deletes all MP related objects from the database. This resulted in locking the OperationsManagerDB for 40 minutes.
So beware of this.
After this i gave the OperationsManagerDB the necessary days to groom itself and then reimported the nWorks VMware MP and the customizations Management Pack.
Why the MP still monitors the VM's, even this is disabled through the nWorks Management Console, that's the question. I will follow up on this one.
Thought this info could be handy for some situations.

I am not sure if one could disable VM monitoring from the Nworks console. One would need to go to the scom console to disable this for VM's. Only the ESX hosts can be managed from nworks console.
Hello Michiel!
Great blog! You may want to check out our nworks MP Operations Guide. On page 11 it discusses what you need to do in order to remove the VMs from the initial discovery. This is in addition to unchecking monitoring for the VMs in our nworks Management Center Console (which you have already done).
Please note, however, that there are metrics and alerts that our nworks Management Pack gives you for the VMs that a SCOM Agent in the VMGuest OS does not give you. Metrics on memory ballooning and cpuReady as well as vCenter alerts such as HA or vMotion failures, etc.
Some things to think about! If you have any questions feel free to contact me or post on our forums at www.veeam.com!

@Sameer, the Nworks Management Center console gives end-users the possibility to enable/disable filters for data types.
Copy from the manual:
The Data Filters is visible on the Management Center tab when the root Management Center object is
selected. These settings allow the end user to turn on and off data collection and publishing within all
Collectors, by data class. Note that this is a global setting and applies to all Collectors. All Classes are
collected by default, which is appropriate for most situations. However, for reasons of scalability (performance,
data storage space, etc.), certain classes can be turned off using the Data Filters check boxes.
I added a screenshot to the blog post.
