System::PerformanceSFlow¶

Introduced : BIG-IP_v11.2.0

The Performance sFlow interface implements the sFlow monitoring standard. The monitoring 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. 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 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. This interface 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 maximum datagram size and datagram revision they support. One or more data sources can be selected to monitor for counter/packet-flow sampling along with sampling rate. Samples would start to flow to the offline receivers at a rate less than or equal to the set sampling rate.
