Management::SFlowReceiver¶

Introduced : BIG-IP_v11.4.0

The SFlowReceiver interface contains the methods for creating and manipulating the sFlow receiver. It allows you to configure one or more sFlow receivers, by providing the IPv4 or IPv6 address and port on which they are listening, along with the maximum datagram size they support and their current state (enabled or disabled). One or more data sources can be selected to monitor for counter/packet-flow sampling. Data samples would start to flow to the offline receivers after you enable them. The sFlow monitoring standard has two major components: Packet Flow Sampling, a random selection of a fraction of the Packet Flows observed at a data source, and Counter Sampling, a periodic sampling or polling of counters associated with a data source. Data samples are sent out, as soon as they are taken, with at most a second of intentional delay, to offline sFlow receivers, through UDP datagrams. It is the responsibility of the receivers to maintain the collected data, in any proprietary format. sFlow analyzers, which understand the receivers or their storage format, could be used to analyze the collected data, to represent network usage, over a period of time. Thus, the collected data can be used to analyze the BIG-IP system performance.
