In a large scale network fabric, it is important to calculate the total number of Sflow samples being created and forwarded per second to collectors. Sending to collectors at a total rate higher than their supported scale (even if this is only a few samples per individual device) can lead to performance issues on the collectors.

This tool is intended as a simple calculator to make that process easier.

The currently configured sample rate will generate more samples than Cloudvision can handle. Reduce the sampling rate to generate under 5000 samples per second.
