Flow Distribution

The Flow Distribution window shows the reponse time of transactions on the specified port. Primarily this is intended to check the performance of DNS servers and the port defaults to 53 for that reason.

Flows that are captured by the Flow Monitor windows are relayed to the Flow Distribution window for analysis. i.e. You must have a Flow Monitor running.

All time measurements displayed have units of Seconds.

Data Source
Select the interface that is to be monitored.
All forwards flows from all interfaces to this window for analysis, otherwise only flows to/from the selected interface will be analysed.

Port

You can monitor any port in the range 1 - 65535. See the note above re the DNS port (53).

Time period

Default: 300 secs
Range: 1 - 86400 seconds
