The historical graph of the collected system stats gives you information about the variation of the stats over a selected time frame.

To view a historical graph:

  1. Go to netwitness_adminicon_25x22.png (Admin) > Health & Wellness.

    The Health & Wellness view is displayed with the Alarms tab open.

  2. Click the System Stats Browser tab.
  3. In the System Stats Browser tab, specify the filter criteria to display the statistics you want.
  4. In the Historical Graph column, select netwitness_histgraph.png.

    The Historical graph for the selected statistic is displayed.

    The figure below gives an example of the historical graph for the Memory Utilization statistic for a host.


    The graphical view is customized to display the statistics collected for the current day and the values are zoomed in for an interval of an hour (10.15 - 11.15 hrs). Hover over the graph to view the details at a particular instant. For example, in the figure it displays the memory utilization at 12.00 hrs.

Note: You can customize the graph view by selecting the Time Frame and Date range. You can zoom in using the zoom in value, time window, or by just clicking and dragging in the plot area. For details on the parameters to customize and zoom in functions, see Historical Graph for System Stats. Any break or gap in the chart line indicates that the service or host was down during that time.
