Configuring Historical Trend and Real Time Graphs for
Virtual Contexts
DM allows you to store historical data for a selected list of statistics calculated over the last hour, 2-hour,
4-hour, 8-hour, 24-hour, or month interval. You can view this historical data as a statistical graph from
specific Monitor > Virtual Contexts monitoring screens. For each monitoring page, default statistics are
defined and the graph drawn for the selected object(s) from the page. DM also allows you to display real
time statistical information related to the selected monitoring window.
Note All client browsers require that you enable Adobe Flash Player 9 to properly display the monitoring
graphs provided in DM.
Historical graphs are available from the following Monitor > Virtual Contexts monitoring windows:
• Traffic Summary window
• Load Balancing > Virtual Server window
• Load Balancing > Real Server window
• Load Balancing > Statistics window
• Context Resource Usage
In each monitoring view window, click the Graph button to view the Graph page. From this page you
can view up to a maximum of four individual graphs of object data. Tooltips appears within each graph
to allow you to see the datapoint values used for plotting.
If you choose, you can overlay multiple objects for comparison on the same graph. Each graph grid
provide a comma-separated list of select statistics.
DM supports a maximum of four lines per historical graph. The number of lines in a graph indicates the
number of combinations of statistics and the objects (which can be a virtual server, real server, virtual
context, and so on). For example, if you select two statistics and two real servers, then the number of
possible combination that can be displayed in a graph is four.
Note The time displayed in all graphs is shown in DM server time not in client time.
