How to properly determine values for "connection-bytes" and "connection-rate" when grouping traffic

Hello Everyone,

I am new to Mikrotik and I have been reading from the Wiki. The topic which I wanted to apply with my current setup is stated in this link https://wiki.mikrotik.com/wiki/Manual:Connection_Rate
My main question regarding this topic:

  1. How do I determine the values for “connection-bytes” and “connection-rate”?
    I wanted to separate the traffic not just in 2 groups. The current example separates traffic using 2 groups with settings connection-bytes=500000-0 & connection-rate=200k-100M
    Are there any tools which can monitor the values for connection-bytes and connection-rate ?
    Let us say I wanted to separate traffic into 3 groups namely: light traffic, medium traffic, and heavy traffic.
    Thanks.
