esaProbeScheduleGroupActionProbeList is a read-write DisplayString (1 to 512 characters) listing esaProbeName values to add or remove from a group's probe list, used together with esaProbeScheduleGroupAction set to add or remove. An administrator uses this pair of objects to incrementally change group membership without having to rewrite the entire esaProbeScheduleGroupProbeList by hand. For example, listing a single new probe's name here and setting the action to add attaches just that one probe to an existing schedule group instead of retyping the whole existing member list.
