7 Application monitoring
This chapter describes application monitoring in NTA. It provides an overview of the application traffic
analysis tasks and the reports they generate, and describes considerations when adding applications to
a task. The chapter also explains how to manage the application traffic analysis tasks and view their
reports.
Application traffic analysis overview
Application traffic analysis tasks analyze network flow data by examining the application data in
network flow records. NTA parses network flow data and provides various statistical views of network
traffic generated by the applications configured in an application traffic analysis task. For example, NTA
provides source and destination host traffic rate information, which shows the rate of traffic attributed to
specific source or destination hosts that were observed sending or receiving application traffic for the
applications specified in a task. Session reports display the source and destination host pairs that are
observed sending or receiving traffic for the specified application. Because analyses based on hosts are
not tied to a specific data source, such as an interface, device, or probe, these reports enable you to view
application traffic rates for all areas of the network that generate network flow records.
The NTA application traffic analysis tasks provide traffic statistics for the applications configured in every
application traffic analysis task. In general, the application traffic reports include rate of traffic for all
applications in all tasks and for the applications in a task. Application statistics provide per-second traffic
rate for each application in a task. Also, they provide distribution of application traffic generated by
source host, destination host, or by a session or source/destination host pair. These reports are
organized into multiple layers from summarized information for tasks to detailed reporting for specific
applications configured for an individual application traffic analysis task.
This chapter looks at the report structure for application traffic analyses, configuration issues around
traffic analysis tasks and the reports they generate. It describes the process for managing application
traffic analysis tasks, including instructions for adding, modifying, and deleting tasks from NTA. This
chapter provides a survey of the summary reports for all application tasks and also looks at the more
granular reports for an individual application traffic analysis task.
Application traffic analysis reporting overview
After you create the first application traffic analysis task, NTA creates an Application Traffic Analysis
Task entry under the Traffic Analysis and Audit area on the left navigation tree.
Click Application Traffic Analysis Task on the left navigation tree to view the summary report for all
application traffic analysis tasks.
Move your mouse pointer to the shortcut menu icon to the right of Application Traffic Analysis Task.
The Application Traffic Analysis Task shortcut menu appears to display all application traffic analysis
tasks created in NTA. Click the name link for a task to view the application traffic analysis report of the
task.
The summary application traffic analysis report provides the following information:
