7.9.2 Using the Aggregration Service for Reports

To improve performance, the Top 10 reports that are included in the Sentinel Core Solution Pack
query the summary tables instead of the events table. The summary tables contain counts over time
for combinations of fields in the event data. This provides a much smaller data set for certain types
of queries and results in much faster queries and report run time.
The Aggregation service is responsible for populating the summary tables with summarizations of
all of the events in the events table. The Aggregation service only generates summarized data for
summaries that are active. The following summaries are required by the Top 10 reports and are
enabled by default:
EventDestSummary

EventSevSummary

EventSrcSummary

Summaries can be activated or disabled by using the Reporting Data configuration window in the
Admin tab of Sentinel Control Center.
The Aggregation service also depends on the
Binary to feed the event data that it summarizes. Therefore, this component must be enabled in order
for the Aggregation service to run properly. This component is enabled or disabled by modifying the
attribute of the
status EventFileRedirectService
ON or OFF. By default, this component is ON.
For more information about EventFileRedirectService and the three aggregation summaries, see
