Tags are user-defined values that can be used to logically group data collection objects such as event sources, event source servers, Collector Managers, Collector plug-ins, event routing rules, report templates, and report results. Tags help you to filter object lists for the data collection objects and also to augment incoming data. You can search for events, report templates, and report definitions that are tagged with a particular tag.
NOTE:Only users in the Manage Tags role can create and manage tags.
