Recording bandwith usage over a time period and showing it using a graph

[kaushalyap]

I am making a feature request here. I would like see bandwich allowing users to record their bandwidth usage over a period of time and showing it using a graph. ex: https://github.com/codebox/bitmeteros

1. For graphing we can use https://github.com/fdehau/tui-rs
2. In order to record bandwidth utilization overtime we have output bandwidth utilization to disk in aggregated fashion.

Hey @kaushalyap - thanks for your suggestion! bandwhich already uses tui-rs to render its UI.
We currently have a PR in the works to display cumulative bandwidth: #155

About displaying it in a graph: I feel this might be beyond the capabilities I'd like bandwhich to have. But maybe this is something that can be implemented on top of bandwhich, either requiring it as a library or using raw_mode and piping it somewhere else?

[kaushalyap]

understandable if you output the stats to db another project can pick things up
ex: https://codebox.net/pages/bitmeteros-bmclient-man

Sure - that can be done with raw_mode, right? bandwhich --raw | something-that-parses-output-and-writes-to-db

[kaushalyap]

Having a flag to aggregate results(for a specific period(day, month), by process) is pretty useful, otherwise someone have to recalculate the aggregated bandwidth consumption from --raw

Another issue :
I am sometimes seeing <UNKNOWN> for process name, why is that?

[imsnif]

How would you suggest such a flag should work?

re: <UNKNOWN>, see this: #149

[kaushalyap]

Seems we have to get #155 done, and we may able to extend things from there.

Anyway I am suggesting some flags like below

• t : aggregated result for the hour
• d : aggregated result for the day
• m : aggregated result for the month
• g : aggregate results by process names

so using something like

• sudo bandwhich -dr -i iName will keep outputting aggregated results for the day
• sudo bandwhich -dgr -i iName will keep outputting aggregated results grouped by process name for the day

And raw output format should contain timestamp in order for other tools parse the output and produce graphs.
