Performance Screens 4-9
The remaining lines of this screen show the data for any intervals containing
errors. Interval 1 is the most recently stored 15-minute interval and interval 96 is
the oldest in the current 24-hour period. On the 30-day screens, interval 30 is the
oldest 1-day interval in the current 30-day period. The real time (or date on
30-day screens) of the interval beginning is shown in the first column.
If more than five errored intervals have elapsed, PAGE-DN appears to the left of
the performance data. Pressing Enter on this field displays the next five errored
intervals. PAGE-UP appears once PAGE -DN is used. Pressing Enter on PAGE -UP
displays the previous five errored intervals. Only intervals containing errors are
displayed, eliminating rows of zeroes. If an interval is not displayed, no errors
were detected during that time period.
The parameters shown on the Performance screens are updated at five-second intervals.
