Graph a Specific Link, Partition, or Class

A report can include up to four graphs of a specific link, partition, or class. By selecting specific criteria, you can generate reports that answer questions such as:

• What was the most bandwidth the FTP traffic class consumed last week?
• Is a partition size appropriate for its traffic class?
• How efficient was my Oracle network traffic? What was its percentage of "good service?"
• What was responsible for my slow Citrix response yesterday — a congested network or a sluggish server?

Note: These types of graphs are not available on the PacketShaper 1200 or 1400 Lite models.

To graph a specific link, partition, or class:

1. In the manage tab:

• In the left window pane, select the link, partition, or class you want to graph.
• Click statistics and choose graph. The Statistics:Reports screen appears.  show screen
  
  or

      In the monitor tab:

• Click the icon next to the class you want to graph. The Statistics:Reports screen appears.  show screen

2. In the Object drop-down menu, select Link, Partition, or Class.

The object you select determines the report types available.

3. Select a report from the Predefined Reports drop-down list. The report types include:

• Utilization (the default)
• Utilization with Peaks
• Shaping Policy Effectiveness
• TCP Connections Initiated
• Connection Efficiency
• Top 10 (Partitions or Classes, depending on selected object)
• Compression Utilization (for units with the compression license)
• Compression Bytes Transferred (for units with the compression license)
• Custom
  
  If the class has RTM data, the following additional reports are available:

• Application Response Time
• TCP Network Health
• Application Response Time vs. Utilization
  
  When you select any report type except Custom, the PacketWise software enters graph suggestions in the center portion of the window; these suggestions are called the report's member graphs.

4. To label the report, enter a report title in the Title field.

5. To include a graph specified in the Graph Type column, select the Include checkbox. Uncheck the Include checkbox if you do not want to include the member graph.

6. To choose additional or different graph types, select the graph name from the drop-down list in the Graph Type column. For descriptions and examples of all the graphs, see Preconfigured Graphs.

Note: You can select the same graph more than once to display information for different time intervals.

7. Determine whether you want to set the same or unique time intervals for the graphs in the report:

• With the default Period setting (as set), you can select a different period for each graph.
• To have each graph use the same time interval, select one of the "same as" options in the Period field. For example, choosing Same as 1 uses the first graph's interval for the other graphs.

8. Enter a number in the Period column and select the units (hour, day, week, or month). The default is 1 hour .

If you selected as set in step 9, set intervals for each included graph. If you selected one of the "Same as" options, you just need to set the interval for the graph you indicated.

9. Determine whether you want the same or unique end date and time settings for the graphs:

• With the default End date and time setting (as set), you can select a different end date and time for each graph.
• To have each graph use the same end date and time, select one of the "same as" options (Same as 1, Same as 2, and so on).

10. Select an end date for each graph. The default end date is now (the current date).

To change the date, select the month and day from the drop-down lists. You can change the date to any time within the past two months.

11. Select an end time for each graph. The default time is now (the current time).

To change the time, select the time from the drop-down list.

12. Click the Display in New Window checkbox to display the report in its own window. When this option is not checked, the report will display in the main browser window.

13. Determine how often you want the report data refreshed.

• Select an interval from the Auto-update Interval field to periodically refresh the data.
• Select auto off if you do not want the data automatically refreshed.

14. Determine the specification details you want the report to include by selecting or unchecking the respective checkboxes for Partition Info, Policy Info, and PacketShaper Info.

• Partition Info includes the partition minimum and maximum size.
• PacketShaper Info lists the IP address, name, and domain.
• Policy Info includes the policy type and settings.

If you are generating and printing the same report from multiple units, be sure to select the PacketShaper Info checkbox to differentiate between the reports.

15. (Xpress only) To include all traffic (compressible and non-compressible) in compression graphs, select the Include Non-compressible Traffic in Compression Graphs checkbox. When this box is not selected (as it is by default), only compressible traffic will be graphed.

16. If desired, select the Include Link and Partition Sizes in Rate Graphs checkbox. When this box is checked, the link or partition size will appear as a horizontal line at the top of link and partition utilization graphs.

17. Click create report to generate the report.

The report appears with included graphs.  show screen  Recent traffic that was not stored in the latest data-sampling interval is not reflected in the graphs.

18. To print the report, click print at the top of the report window.

Note: If a graph shows the partition size to be less than the actual size that was set, the unit is oversubscribed (that is, the sum of all partitions is greater than the link size). In the case of oversubscription, PacketWise adjusts the programmed value to a scaled value, and uses the scaled value in the graph.

Additional Information

The traffic class you select for a report determines the graphical information you can see. Factors that influence the available reports and graphs are whether the class is a parent or a leaf class (a class with no children), whether the class tracks response times, and whether the class has an associated partition.

The object type (class, partition, or link) also affects the type of graphs available to you. For example, a partition offers a report and graph called "Top 10 Partitions," but a link does not. As another example, all three object types offer a Utilization report, but the reports contain different member graphs.
