sFlow collects statistics only for traffic *received* on the interface. If you want to monitor traffic *sent* on the interface, you need to enable sFlow on the corresponding interface in the opposite direction.
Optionally, you can specify the sampling rate for the interface using the following command:
Optionally, you can specify the number of bytes from each packet that should be included in the sFlow sample using the following command:
.. cfgcmd::
set vpp sflow sample-rate <rate>
set vpp sflow header-bytes <bytes>
This will set the sampling rate for the specified interface. The default sampling rate is 1, which means that every packet is sampled. A higher sampling rate means that fewer packets are sampled, which can reduce the amount of data sent to the sFlow collector. This can be useful in high-traffic environments to reduce the load on the collector.
This defines the size of the packet header (in bytes) captured for each sFlow sample.
The sampling rate is configured globally under the ``system sflow`` section and automatically applied to VPP sFlow.
This ensures consistent sampling behavior between the system and VPP, and prevents configuration conflicts.
Finally, you need to enable integration between VPP and the kernel sFlow agent using the following command:
