Collection Statistics
Collection statistics are quantitative data that can be collected for a target. This
includes statistics directly reported in NetFlow records, such as bytes
transferred, as well as information that can be derived indirectly, such as the
number of unique clients seen using an application.
An ExtremeAnalytics engine can track the following statistics:
l Bytes — The number of bytes transferred in both directions, between the client and
the server. Also known as bandwidth. You can track sent and received bytes as well
as total bytes.
l Flows — The number of NetFlow records sent by the switch to report the traffic
between the client and the server. You can track inbound and outbound flows as
well as total flows.
l Clients — The number of unique clients associated with the target.
l Applications — The number of unique applications associated with the target.
l Network Response Time — The average amount of time to create a connection.
