into a single task. Another option is to create a single task for every device, and add all of the
interfaces from that device for which you want to view statistics into the task. Also, you can create
tasks organized by support team so that operators have simplified access to reporting for the
devices and interfaces they manage.
• Add only those interfaces for which you want to view statistics. Do not add all of the interfaces on
a device unless you want to view reporting for all interfaces. Adding interfaces for which you do not
want to view statistics only clutters NTA interface navigation. This makes it more difficult for you to
find the interface for which you do want to view data.
• When you add interfaces to a task, NTA presents a list of all interfaces that NTA knows about. This
list is generated from the devices that have been added to NTA using the Device Management
feature. If the interfaces you want to add do not appear on this list and if they are not already
included in another interface traffic analysis task, it is most likely because the device has not been
added to NTA or it has not been selected in the NTA server configuration found under Server
Management. For more information about selecting devices in NTA server management, see
" Modifying an NTA server configuration ."
• If you do not add an interface to a task, NTA does not report on it.
• You can add an interface to only one task. Careful planning of tasks and documenting them will be
a valuable aid to you when you begin creating tasks and to help identify to which task an
application has been added.
• You must enable network flow data on the devices and for the interfaces you want to monitor and
report on using NTA.
Managing interface traffic analysis Tasks
NTA processes, analyzes, and reports on network flow data through the tasks that administrators create.
Until a task is created, NTA does not analyze the data that devices forward to it or that it is configured
to receive. Effective management of tasks results in the reporting you need. The following information
describes the process for adding, modifying, or removing interface traffic analysis tasks in NTA.
Viewing a traffic analysis task
NTA displays all traffic analysis tasks in the Traffic Analysis Task List.
To view the NTA traffic analysis task list:
1. Select Service > Traffic Analysis and Audit > Settings.
2. Click the Traffic Analysis Task Management link in the Settings area of the Traffic Analysis and
Audit page.
NTA displays all tasks in the Traffic Analysis Task List in the main pane of the Task Management
page.
Task list contents
• Task Name—Contains the name of the task. The contents of this field serve as a link to the
Traffic Analysis Task Details page for the associated task.
• Task Description—Contains the description for the associated task.
• Task Type—Identifies the task type, which can be interface, VLAN, probe, application, host,
VPN, or inter-business.
