Configuring sFlow
sFlow® is the standard for monitoring high-speed switched and routed networks. sFlow technology is built into
network equipment and gives complete visibility into network activity, enabling effective management and
control of network resources.
The sFlow monitoring system consists of an sFlow Agent (embedded in a switch or router or in a standalone
probe) and a central sFlow Collector. The sFlow Agent uses sampling technology to capture traffic statistics
from the device it is monitoring. sFlow datagrams are used to immediately forward the sampled traffic
statistics to an sFlow Collector for analysis.
The sFlow Agent uses two forms of sampling: statistical packet-based sampling of switched or routed Packet
Flows, and time-based sampling of counters.
sFlow Agent Summary
Packet Flow Sampling and Counter Sampling are performed by sFlow Instances associated with individual Data
Sources within the sFlow Agent. Packet Flow Sampling and Counter Sampling are designed as part of an
integrated system. Both types of samples are combined in sFlow datagrams. Packet Flow Sampling will cause
a steady, but random, stream of sFlow datagrams to be sent to the sFlow Collector. Counter samples may be
taken opportunistically in order to fill these datagrams.
In order to perform Packet Flow Sampling, an sFlow Sampler Instance is configured with a Sampling Rate. The
Packet Flow sampling process results in the generation of Packet Flow Records. In order to perform Counter
Sampling, the sFlow Poller Instance is configured with a Polling Interval, The Counter Sampling process results
in the generation of Counter Records. The sFlow Agent collects Counter Records and Packet Flow Records and
sends them in the form of sFlow datagrams to sFlow Collectors.
