Solved Groups appearing grey
On my dashboards (in both Squared Up and SCOM) my groups are grey, why?
The groups contain servers, which are all green. I was expecting the group to be green too.
Best answer
When you create a group in SCOM it does not by default have a health rollup monitor, so the health state stays in the grey/uninitialized ‘no health information’ state. To show the health of the group members using the group object you will need to add a health rollup monitor.
- In SCOM click on the ‘Authoring’ tab
- Expand ‘Management Pack Objects’.
- Right click on ‘Monitors’, select ‘Create a Monitor’ and then ‘Dependency Roll Up Monitor’.
- Give the monitor a suitable name.
- The Monitor Target should be your group.
- Leave the ‘Parent monitor’ set to ‘Availability’.
- Select the same unsealed management pack that your group is in.
- Click Next to move on to Monitor Dependency.
- Expand Object (Contains Entities), select Entity Health.
- Click Next, Next, Create.
After you have created a health rollup you may have to wait a minute or two and then your dashboards should show the health for your group.
Here is a blog that provides a very straightforward walkthrough with screenshots.
If you have this on lots of groups and want to quickly create health roll-ups I would suggest using the link below to use Tao Yang’s Management pack. It’s really easy to use.

An other easy way to do it, and a little bit faster if you have many to create is:
1 Click ‘Monitoring’
2 Click Discovered Inventory’
3 Search for the group
4 Click ‘Configure Health roll up’ under tasks on the right hand side
I found that even with the health rollup added, occasionally the health state does get out of sync. This article explains how to fix this. Here’s a summary of the steps:
- Download the System Center Internal Task Library
- Run the ‘Resubmit local cache for state change events’
- Your rollup is fixed!
- This fixes the issue because it forces a recalculation of the roll-up monitor as well – awesome!
