Analysts can filter the results in the Investigation > Events view and, by searching for events or selecting the service on which to view events, set the time range, and query meta data.
If you opened the Events view from a Navigate view drill point, the view opens to the Detail view of events by default. Analysts who do not have permissions to use the Navigate view can query services directly from the Events view. There are several configuration options to filter the information displayed in the Events view.
Note: When an Archiver is the currently selected service in the Events view and you are searching against a Broker or Concentrator, the search is slower than if searching against a Broker or Concentrator because the data on the Archiver is compressed and there is typically more data.
