ExtremeAnalytics Unidirectional Flow Tables


This table on the Application Flows tab displays unidirectional flow data stored in memory. It displays the raw, non-aggregated flow data received from the flow sensors on the network. It presents flow data for real-time troubleshooting purposes, and is not designed for historical long-term flow collection. A check mark () in the table denotes a tracked application or a tracked site.

Hover over an application in the table to display switch data, which is an accumulation of multiple switches into single flow record, as well as the path that flow has taken.

By default, the top 100 entries are displayed in the table. However, you can change this value using the Max Rows field at the bottom of the view.

Text at the bottom of the table shows Base Flows, using X number of days, hh:mm:ss format, and including Current Load and Peak Load calculations in flows per second.

Following are definitions for the table columns:

Flow Summary

Rest the cursor over the first column in the table and select the arrow to open the Flow Summary window for a specific flow. Flow summary information can include response times, Uniform Resource Identifier, and header data for the flow. In the Flow Summary window, use the Gear menu to access additional functionality such as the ability to modify the application fingerprint or create a policy rule.

Client/Server Flows

Identifies whether the flow is a Client Flow or a Server Flow . The client/server direction of a flow is calculated by the ExtremeAnalytics engine. Hover over the icon to see a tooltip with more information.

Source Address

The IP address or hostname of the system where the flow originated. Select on the Source address link to open a PortView for the client or server (if it is in the database) or a PortView for the switch configured as the NetFlow sensor.

Source Port

Either the TCP or UDP port on the client/server handling the flow.

Destination Address

The IP address or hostname of the system that received the flow.

Destination Port

Either the TCP or UDP port on the system that received the flow.

Application

The name of the application as identified by the ExtremeAnalytics engine using the Fingerprint database.

Application Group

The flow application group to which the application belongs.

Application Info

Additional information about the flow provided by the ExtremeAnalytics engine.

Type

The content type of a flow, such as sound, video, or text. Select on the Type icon to open the flow's URI.

Network Response

The response time (in milliseconds) that it took for the TCP request to complete.

Application Response

The response time (in milliseconds) that it took the application request to complete.

Site

The site where the flow originated.

Detailed Site

The client's switch IP and switch port (wired), or controller IP, AP, and SSID (wireless).

Device Family

The operating system family for the client end-system.

User

The username used when the client system connected.

Profile

The ExtremeControl profile assigned to the client end-system.

Protocol

The connection type protocol used by the flow.

Last Seen Time

The last time the flow was seen.

Duration

The amount of time that the flow was active.

Rate

The average bandwidth for the flow based on the flow duration.

Packets

The number of packets in this flow. For flows collected via Application Telemetry, this number can be estimated.

Bytes

The number of bytes in this flow. For flows collected via Application Telemetry, this number can be estimated.

NetFlow Records

The number of NetFlow records for this flow.

Flow Source

The IP address of the NetFlow source switch, Application Telemetry source switch, or wireless controller sending the Flow data to the Flow collector.

Input Interface

The interface receiving the flow on the Flow sensor.

Output Interface

The interface transmitting the flow on the Flow sensor.

TOS

The DSCP (Diffserv Codepoint) value for the flow. The TOS/DSCP value is used to configure quality of service for network traffic.

TTL

The TTL (IP Time to Live) value of the flow. The TTL field indicates the maximum number of router hops the packet can make before being discarded. The TTL field is set by the packet sender and reduced by every router on the route to its destination. When the value hits zero, the packet is dropped.
