The Bandwidth link on the Groove Relay administrative Web page displays bandwidth usage samples taken at prescribed intervals for devices contacting the Groove Relay. Relay bandwidth statistics reflect the bandwidth (bytes per second) used by Groove client devices enqueueing and dequeueing data on the Groove Relay over a specific time interval. From this bandwidth page, you can click a device sample to view detailed information about a specific identity, as described in the table below. The Lookup text box lets you specify the maximum number of devices for which to display information.

The reporting of bandwidth usage statistics is a Groove Relay feature that is enabled or disabled through a Windows registry setting. The feature is enabled by default. For information about configuring bandwidth usage statistics, see Configuring Bandwidth Usage Statistics.

The following table summarizes bandwidth usage statistics:

Table 3. Bandwidth Usage

Bandwidth Usage Statistics Description

Enter the top number of devices to display:

Accept the default of 25 to display bandwidth usage statistics for up to 25 Groove client devices per page, or enter another value in this field. Then click the Lookup button to display bandwidth usage for each Groove client device registered with the Groove Relay, up to the number specified in this field. The list of devices appears in descending order of bandwidth usage.

The values on this page represent the bandwidth used by each device enqueueing and dequeuing on this Groove Relay since the last polling interval, or since server startup.

To view detailed statistics for a selected device, click the device. Two groups of statistics appear, as follows:

General bandwidth usage - Displays average bandwidth usage for all device activity, followed by separate average, maximum, and minimum usage values for enqueuing and for dequeuing, as described in this table.

Detailed bandwidth usage - Displays average, maximum, and minimum bandwidth usage for dequeuing, as described below in this table.

Note: To disable this statistic, you add a new value to the Windows registry, as described in Disabling/Re-enabling Bandwidth Usage Statistics of the Managing a Groove Relay section of this document set.

General Bandwidth Usage (Bytes/Sec) Since Last Poll:

-

Average Bandwidth Usage

The average bandwidth in bytes per second used by the selected device to enqueue and dequeue Groove data on the Groove Relay since the last poll.

The Groove Relay totals the bandwidth usage for each enqueueing or dequeueing device over a polling interval. Samples are collected from this interval and averaged to produce the average bandwidth. The Groove Relay calculates this value from samples collected between the last polling interval (or server startup if less than the last polling interval) and the Lookup time.

The default polling interval is 2 minutes. The default sample interval (size) is 2 seconds. You can change the sample and polling intervals in the Windows registry, as described in Disabling/Re-enabling Bandwidth Usage Statistics.

Average Enqueue Bandwidth Usage

The average bandwidth used by the selected device to enqueue Groove data on the Groove Relay since the last poll.

Maximum Enqueue Bandwidth Usage

The maximum bandwidth used by the selected device to enqueue Groove data on the Groove Relay since the last poll. Maximum bandwidth is the largest sample value collected between the last polling interval (or server startup) and the Lookup time. See the description of Average Bandwidth Usage, above, for more information about polling.

Minimum Enqueue Bandwidth Usage

The minimum bandwidth used by the selected device to enqueue Groove data on the Groove Relay since the last poll. Minimum bandwidth is the smallest sample value collected between the last polling interval (or server startup) and the Lookup time. See the description of Average Bandwidth Usage, above, for more information about polling.

Average Dequeue Bandwidth Usage

The average bandwidth used by the selected device to dequeue Groove data on the Groove Relay since the last poll.

Maximum Dequeue Bandwidth Usage

The maximum bandwidth used by the selected device to dequeue Groove data on the Groove Relay since the last poll. Maximum bandwidth is the largest sample value collected between the last polling interval (or server startup) and the Lookup time. See the description of Average Bandwidth Usage, above, for more information about polling.

Minimum Dequeue Bandwidth Usage

The minimum bandwidth used by the selected device to dequeue Groove data on the Groove Relay since the last poll. Minimum bandwidth is the smallest sample value collected between the last polling interval (or server startup) and the Lookup time. See the description of Average Bandwidth Usage, above, for more information about polling.

Detailed Dequeue Bandwidth Usage (Bytes/Sec) Since Last Poll:

-

Identity

A Groove identity that dequeued on the Groove Relay since the last poll. Dequeuing statistics appear for each identity dequeuing from the selected device since the last poll.

Note that, following Groove’s SSTP protocol, separate identity information is provided for dequeuing only, not for enqueuing.

Average Dequeue Bandwidth Usage

The average bandwidth used by an identity dequeuing on the Groove Relay from the selected device since the last poll.

Maximum Dequeue Bandwidth Usage

The maximum bandwidth used by an identity dequeuing on the Groove Relay from the selected device since the last poll.

Minimum Dequeue Bandwidth Usage

The minimum bandwidth used by an identity dequeuing on the Groove Relay from the selected device since the last poll.
