Menus in the Matrix Group display statistics about conversations between devices. You can view the statistics in table form or graphically as a conversation matrix. Matrix information can be displayed for a set of selected nodes, or for the most active nodes using the TopN Talkers command from the Hosts Group.
Displaying conversation statistics
To display conversation statistics for each device pair in the selected network, choose Matrix and then Display Matrix from the RMON menu. The MIB table window is displayed.

Network name
Node name or MAC address for the device generating traffic
Node name or MAC address for the device the traffic is directed to Statistics saved for the conversation, including total packets,
total bytes, and total error counts |
The source and destination addresses are converted to Network Manager node names. From the Config menu, choose Options, then Use MAC Address as Node Name to toggle between MAC address and node name display.
Viewing a real-time image of device conversation
- Select two or more nodes that are attached to a monitored network OR select two or more devices in the Show TopN Talkers dialog box and click Matrix.
- From the Matrix menu, choose Show Conversation Matrix. The data download process begins.
- After downloading an initial set of data, the program prompts you to enter a poll interval. You should not set this too small because a large amount of data is downloaded during each poll interval. A larger poll interval also provides a more representative display.
- Click OK to continue. The Matrix window is displayed.
Each monitored device is listed around a circle. The Network Manager node name is used if it matches the MAC address supplied by the RMON probe. Otherwise the MAC address is shown. Lines are drawn between nodes that are communicating. The thickness of the line represents the relative amount of traffic.
You can select two devices on the image by holding down the left mouse button, clicking a node icon, and dragging the mouse to the other device icon. After you select two nodes, the Chart and Graph buttons become active.
Viewing the conversation in a graph or chart
Use the Graph button to display a real-time graph for conversation statistics between the two selected devices, or the Chart button to display a real time chart for conversation statistics between the two devices. Two graphs or charts are displayed, one for each direction in the conversation. The poll interval for the graphs or charts is set to the matrix poll interval.
Changing polling time
To change the number of seconds between polls, choose Poll interval from the Matrix menu. Enter the new polling interval in the dialog box that is displayed.
