Real Time Traffic Profile

The Real Time Traffic Profile is a graphical tool, which allows the user to monitor a wide variety of traffic on the bus and manipulate the display of that information.

To start up a Real Time Traffic Profile:

  1. Open a new Project: From the Main Menu, select File > New Project.

  2. The Add Device To Project window appears. In this example, an M408 Analyzer is available to add to the Project.

By default seven panes are displayed:

  • Frames Rate

  • Payload Rate

  • IO Command Write

  • Error Count

  • Average Frame Size

  • Link Utilization

  • IO Command Read

In this case, we have data being generated and sent to the analyzer. The controls for the Real Time Statistics – Traffic Profile are shown below.

Start Real Time Traffic Display

To start the analyzer collecting data: Select the Start icon and each of the windows in the grid display will show filtered activity. In this case we’ve set the Filter to Any Ethernet Frame, so we see a lot of activity and no Errors were detected.

Manipulating Individual Windows

Each window can be docked or undocked from the display. Each window can also be duplicated or deleted. By deleting some graphs and adding others, you can graph individual ports to compare specific parameters.

This is just one example of the flexibility of the windows being displayed. You can manipulate the types of traffic being displayed to suit your individual preferences.

Individual Window Controls

Each window has five control icons:

  • Zoom In

  • Zoom Out

  • Settings

  • Pop Window Out of Current Display

  • Close Current Display

As an example, the controls for Payload Rate are shown below.

Settings – Filter

Settings allows you to set up filters for the traffic you want to see, as well as detect a wide variety of protocol errors. In the display above we can now see that the only Filter Setting is Any Ethernet Frame.

If you don’t know exactly what you want to filter out of the traffic, one method would be to Record a Snapshot of the traffic you’re interested in and use it as a guide for defining your filter.

For example, if you were running SCSI traffic into the analyzer and took a Snapshot.

Snapshot of Traffic

Notice that the traffic is mainly SCSI commands and data on Ports 1 and 2. In the filter window, choose the following filters.

Any time you change either Filter or Visual Settings this Warning message will pop up:

If you compare these graphs with earlier ones, you’ll notice the reduced amount of traffic because of the filters added.

Selecting Light will generate a light colored background for the displays.
