sFlow (defined in https://sflow.org/sflow_version_5.txt) is a standard-based sampling technology the meets the key requirements of network traffic monitoring on switches and routers.
sFlow is an industry standard, low cost and scalable technique that enables a single analyzer to provide a network wide view.
Example model & SONiC version:
SONiC only supports two sFlow collectors.
Defaults:
The default sample rate based on interface speed is:
1-in-1000 for a 1G link
1-in-10,000 for a 10G link
1-in-40,000 for a 40G link
1-in-50,000 for a 50G link
1-in-100,000 for a 100G link
Enable sFlow:
admin@sonic:~$ sudo config sflow enable
admin@sonic:~$ sudo config sflow interface enable Ethernet32
Sometimes may result in error: |
Failed to enable unit: Unit file /etc/systemd/system/sflow.service is masked.
Fix:
sudo systemctl unmask sflow >/dev/null
sudo systemctl enable sflow
sudo systemctl start sflow
Add an sFlow collector.
admin@sonic:~$ sudo config sflow collector add sFlow 192.168.10.2
Check the result:
admin@sonic:~$ show sflow
