Tungro (/Seritus)

OK you wonderful bunch of nerds! I could do with some help.

I need to get an estimate of how much network traffic a CUPS server uses. What tool could I use to monitor it over a period of time (say a week)?
Note, this server does more than just CUPS so I can't just take network interface stats, that'd be too easy!
A resolution of hourly would probably be fine.

@tungro is the port CUPS uses unique or is it shared by any other service? If it’s unique, it seems relatively easy to monitor that port…

@emilvolk @tungro Yeah, I think it's port 631. However, I'm not sure if that's just the Web UI port, or if that's where printer traffic goes, too.

Tungro, you might try a nftables accounting rule to see how much traffic goes to that port.

@tungro probably overkill. But a netflow exporter on the box or near it on the network would do the job.
