i am new too this. but is there an easy way to find out what service does what?
specifically i need to monitor tx/rx bandwidth on ether1 on an rb433. i found an example on how to do it on a wlan interface, but not on a ether interface...
kind regards

I don't understand the question. Monitoring packet counters on an ethernet interface is exactly the same as monitoring packet counters on a wireless radio interface.

You can't convert it because you cannot possibly know how large each packet was. If you want bps values that's just a different SNMP OID to query. It's still the same regardless of interface type, tho.

hmm...
i found something thats a little closer, but nothing that looks like bps
iflnoctets
1.3.6.1.2.1.2.2.1.10.1
"The total number of octets received on the interface,
including framing characters.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime."

I misspoke before. There is no such thing as a bps value to retrieve. The monitoring software retrieves the number of bytes at time x, and again at time y. It then calculates the bps rate based on the delta between the values.
