Flow Statistics View


To look at statistics detailing switched and forwarded traffic, click the Monitor Tool Flows button to present the Flow Statistics View. The following figure shows an example of the Flow Statistics View (partial screen).

The following section describes the fields in the Flow Statistics View.

Interval
Every five minutes, the network is polled and the information is displayed at the Flow Statistics View is sequentially generated rows. Up to 12 rows, or those associated with the past hour, are displayed. Each poll measures the traffic for the previous five minutes only. Blank rows signify polling intervals that have not yet occurred.
Switched Traffic
Switched traffic is network traffic that the GIGAswitch/IP Switch Controller flow characterization algorithm has redirected to the switch. It does not pass through the GIGAswitch/IP Switch Controller.
Switched traffic normally consists of long-lived flows such as video, bulk data transfers, and so on.
Forwarded Traffic
Forwarded traffic is network traffic that the GIGAswitch/IP Switch Controller flow characterization algorithm has not switched. This traffic has been forwarded by the GIGAswitch/IP Switch Controller.
Forwarded traffic usually consists of short-lived flows such as DNS queries, short E-mail transports, ICMP pings, and so on.

State Statistics

To get statistics on flow states and general flow data, click the State Statistics link at the bottom of the Flow Statistics View. The following figure shows an example of this link text.

A screen containing flow states and general flow data is presented. The following figure shows an example.

The following section describes the Flow States fields of the Flow Statistics View.

Input on Default VC, Output on Default VC
The number of cells received and transmitted on the default virtual circuit. These counts correspond to cells not categorized into flows by upstream or downstream neighbors.
Input on Default VC, Output on VCy
The number of cells received on the default virtual circuit, but sent out on a specific, numbered virtual circuit.
Input on VCx, Output on Default VC
These statistics give the number of cells received on a specific, numbered virtual circuit, but sent out on the default virtual circuit.
Input on VCx, Output on VCy
These statistics give the number of cells received on a specific, numbered virtual circuit, and sent out on a specific, numbered virtual circuit. These counts correspond to cells categorized into flows by both
upstream and downstream neighbors.
Total Flow State Transitions
The number of times flows have been created or destroyed.

The following section describes the General Flow Data fields of the Flow Statistics View.

Unicast Flows
The number of unicast flows that have been created through this switch.
Multicast Flows
The number of multicast flows that have been created through this switch.
Average Flow Lifetime (<30 secs)
The number of unicast and multicast flows with an average flow lasting less than 30 seconds.
Average Flow Lifetime (>30 secs)
The number of unicast and multicast flows with an average flow lasting more than 30 seconds.
Flows Failed: No Available VCI
The number of unicast and multicast flows that failed because the virtual circuit identifier was not found.

Message Statistics

To get statistics on IFMP and GSMP message data, click the Message Statistics link at the bottom of the Flow Statistics View. The following figure shows an example of this link text.

A screen containing IFMP and GSMP Message statistics is presented. The following figure shows an example of this screen.
