Summary reports provide a high-level view of system activity. A summary report can consist of one line of data that summarizes system activity for each interval within the reporting period, a single line of data giving summary totals for all RMF intervals within the reporting period, or both interval summary data lines and a total summary data line. Figure 1 shows a sample summary report, including both an interval summary line for each RMF measurement interval and a total summary line for all of the intervals.
