Maybe you think this is clever snark.
But some people might not want to help you if you talk like that.

There is extensive documentation for arm and stem (the backend library
used by arm). It's some of the best documentation I've seen.

Here is the documentation for arm:
https://www.atagar.com/arm/

Here is the documentation for stem:
https://stem.torproject.org/index.html

In particular:
https://stem.torproject.org/api/descriptor/server_descriptor.html

• average_bandwidth (int) -- * average rate it's willing to relay in bytes/s
• burst_bandwidth (int) -- * burst rate it's willing to relay in bytes/s
• observed_bandwidth (int) -- * estimated capacity based on usage in bytes/s

And:
https://stem.torproject.org/api/descriptor/extrainfo_descriptor.html

	• read_history_end (datetime) -- end of the sampling interval
	• read_history_interval (int) -- seconds per interval
	• read_history_values (list) -- bytes read during each interval
	• write_history_end (datetime) -- end of the sampling interval
	• write_history_interval (int) -- seconds per interval
	• write_history_values (list) -- bytes written during each interval
