Hi Dan,
Unfortunately, at this time SYSVIEW does not have the ability to issue an alert based on a group of lpars exceeding a capacity limit.
If this is a feature you would like to see in a future release of SYSVIEW, you can create an idea here on CA Communities for that functionality to be added to the product in an Enhancement Request. You can create an idea by clicking the pencil drop down menu towards the top right of the CA Communities site and selecting the Idea option.
Thanks,
Neil Kitzmiller, CA SYSVIEW Support
