biking_viking Do you NEED to see the status for every single node in the group, or do you just need to know the status of the group? In other words, if you have 10 nodes in the "myTest" group, and they are all up, do you need to see 10 results that all say up? Or, if you have 10 nodes in the "myTest" group, and there are 1 or more that are down, would being able to see the group as a whole, indicating there are down nodes in the group, work to accomplish your goal?
If you are really only looking for the group status, then there is a nice default widget already waiting for you to use. The "Groups With Problems" widget will list all groups, and the overall status of each group. Furthermore, you can edit that widget to filter down to a more specific subset of results.
Additionally, if you are wanting/needing to get into custom SWQL queries, I would highly recommend you take a look at the Orion SDK/API. It is an easy, and excellent, way to learn SWQL, and customize your dashboards to fit your needs.
