• Average Rate (Last 1 Hour)—This bar graph provides summarized average traffic rate per second
reporting for all applications specified in all application traffic analysis tasks summarized by task
for the last hour. Each bar in the graph is a link to more detailed reporting for the selected task. This
includes reporting for traffic rates, source, destination, and session statistics. Each of these detailed
categories include several reports:
{
Traffic—Reports found under the Traffic tab for application reporting include traffic trends that
display the average rate per second attributed to the applications in the selected task and the
data samples for the applications in the selected task.
{
Source—Reports found under the Source tab for application reporting include a pie chart
showing the percentage of traffic generated by the TopN source hosts. Also included is a
tabular list showing volume and percentage of traffic generated for each of the TopN source
hosts that generated traffic for the selected application.
{
Destination—Reports found under the Destination tab for application reporting include a pie
chart showing the percentage of traffic generated by the TopN destination hosts. Also included
is a tabular report showing volume and percentage of traffic generated for each of the TopN
destination hosts that generated traffic for the selected application.
{
Session—Reports found under the Session tab for application reporting include a pie chart
showing the percentage of traffic generated by the TopN source and destination host pairs.
Also included is a tabular report showing volume and percentage of traffic generated for each
of the TopN source and destination host pairs that generated traffic for the selected application.
• Traffic Trend for Selected Task (Last 1 Hour)—This line chart provides the per second average traffic
rate summarized by application traffic analysis task for the application tasks you select.
• Summary List (Last 1 Hour)—This list provides the per second traffic rate and the total volume of
traffic summarized by the application traffic analysis task. This list enables you to navigate to more
detailed application reporting for the selected task.
Application traffic analysis configuration considerations
There are several things to consider when you add applications to a task, the most important of which is
determining the applications that belong to each task. Consider the following:
• By default, NTA does not monitor any applications. Therefore, you must create a task for every
application or group of applications on which you want to monitor and report.
• You must anticipate the locations on your network where you are certain to capture application
data. You must enable network flow data for the devices and the interfaces on them for those
locations on your network where you know the application for which you want to monitor traffic can
be captured. Then, you must add these devices and probes to NTA using the Device Management
and Probe Management features in NTA. NTA then summarizes application data for all devices
and probes on which it observes the application traffic.
• NTA provides summarized application reporting based on the way you group applications into
tasks. Consider how you want to summarize, access, and view application data. Then, structure
your tasks around it. For example, you can create an application task called NetMgmt and add all
of the applications used that support the network management function for your environment. NTA
summarizes all traffic observed for all applications into the group NetMgmt and attribute traffic in
the reports to the task name you have configured.
• When you add applications to a task, NTA presents a list of all applications that NTA knows about.
This list is generated from the applications that came predefined in NTA and to which user-defined
applications have been added. If the applications you want to add do not appear on this list, it is
