In the NPM event log the options to filter devices by Network Object or Type of Device work well. It would be helpful to also have an option to Filter by Group Membership. I've grouped all my devices by Site and then have a few subgroups for specific device types so that my service desk can quickly ID issues by site. It would help to have a filtered event log that contained all the events for devices based on a group membership. If the subgroups could also be displayed that would also be a major benefit so that a filterd eventlog could be attached to incident/problem tickets.
