The administrator then ﬁlters events and bases alerts on this functional group. Other common uses for functional rather than policy-centric groups include TestMode settings, ADI, and software updates. Each of these groups is tied to groups and not to speciﬁc hosts. Rather than forcing all hosts in a large group to perform any of the previous tasks, you can simply create groups for these tasks and move agents in and out of the functional group as necessary.
