The historical performance viewer is a console included with Monitor Solution that lets you view historical performance data. Historical data is available from both the Monitor Plug-in and the Remote Monitor Server.
To view historical performance data
The time period that you specified in From and To may contain no data in the beginning or at the end of the period. In this case Summarized View shows only the actual time when the data is available. The empty time line with no data in the beginning or at the end of the chart is not displayed.
If available, the data that was last gathered for the selected point is displayed in the following sections: Processes, Events, Ports, and Text Data. The Metrics section continues to display the average, minimum, and maximum values for the whole range of data that is displayed in the Detailed View. However, the Last Value and Last Time columns in the Metrics section display the value at the selected point. If the selected point has no value, these columns display the value that precedes this point. If no value is available for the metric in the Detailed View, the Last Value and Last Time columns are left blank in the Metrics section.
