Traffic Flow Portlet
Traffic Flow Analyzer uses several types of portlets, one for each of the types of objects on which it
reports. These are Applications, Autonomous Systems, Conversations, Endpoints, Exporters by
Equipment Manager, Exporters by Subcomponent, Protocols, Receivers and Senders. Note that
Endpoints, Conversations, Receivers, and Senders all have similar data. The way it works is that
every flow has a sender and a receiver, and these are both considered endpoints. Also if endpoint A
sends a packet that is received by endpoint Z and then Z sends another packet back to A, these
packets are both part of the same conversation between A and Z.
When you add one of the traffic flow analyzer portlets to a page, its summary, or minimized form
appears. This displays a simple view containing a pie chart and a table showing the summarized
collected data over the configured time period. Only the time frame (shown with a clock icon), the
mode of calculation (shown with a calculator icon), and the flow direction (ingress, egress, or both)
can be changed in this view. These controls appear as dropdown buttons in the upper right corner
of the portlet. Most minimized traffic flow portlets are limited to the top entities as measured by
total bytes. The minimized Exporters by Equipment Manager portlet is not limited to 5 entries. It
supports pagination in the event that there are lots of exporters, so that all the necessary data can
be shown.
To see more information about any item within the minimized traffic flow portlet, you can click on
the name and this will navigate to the expanded traffic flow portlet, as shown in the context of the
selected item. Another way to navigate to the expanded portlet is to click on the + sign in the
upper right corner.
The
Expanded Traffic Flow Portlet displays an interactive graph. You can also Drill Down to
details about components within this portlet by clicking on one of the links in the table below the
graph.
NOTE:
The selected period determines whether data is present, especially if you have just started monitoring
Traffic Flow. Choose the shortest period to see data immediately (it still takes a few minutes to appear),
and select longer periods only after monitoring has run for longer periods.
