This article describes how build an inexpensive Raspberry Pi 5 based server for real-time flow analytics using industry standard
sFlow streaming telemetry. Support for sFlow is widely implemented in datacenter equipment from vendors including: A10, Arista, Aruba, Cisco, Edge-Core, Extreme, Huawei, Juniper, NEC, Netgear, Nokia, NVIDIA, Quanta, and ZTE.
In this example, we will use an 8G Raspberry Pi 5 running Raspberry Pi OS Lite (64-bit). The easiest way to format a memory card and install the operating system is to use the
Raspberry Pi Imager (shown above).

YES to apply the settings and create a bootable micro SD card. These initial settings allow the Rasberry Pi to be accessed over the network without having to attach a screen, keyboard, and mouse.
ssh [email protected]
Use ssh to log into Raspberry Pi (having installled the micro SD card).
