I am trying to make custom queries to populate alert rules, but I can not find tables to query.
Hello, the table you're looking for is most probably ContainerMemberSnapshots. This table contains current members, based on both Static and Dynamic group member definitions. I hope this helped.
More to the point...I want to populate a custom property based on a node's group membership.
May be a little late now, but how did you manage to do the Custom Property based on the Group Membership?
