bandwidth, traffic monitoring?

[ayryq]

I switched this week from a ASUS router running tomato to a TP-link TL-ER6120 and Ubiquiti UniFi access points. I love the stability and speed of the router, and the great connections through the APs, but there's one thing I miss.

TomatoUSB had all these great graphs and charts. I could monitor (in real time or over the past X hours/days) how much data each device was using, or how much my guest network was using vs the private network. I could even track what URIs and search strings were being used if I wanted. I don't need this stuff, but it was cool.

Is there any way to get this sort of data now? TP-Link only provides a number of bits up/down (I think, since the router was rebooted). UniFi shows the total data used by each wireless client, and a chart of how many clients over time.

How can I get more data? The new router has a port-mirroring function. And I've got a spare router now, running Tomato.

Thanks in advance for your responses - this is my first post here.

If the box supported SNMP, I'd recommend looking into something like Cacti. But since the specs for this device don't mention it, I don't think that is an option.

Thanks,
I returned the TP-Link and bought a ZyXEL Zywall USG 50. I get slightly better statistics and, it seems, a much more feature-filled router in general. I also signed up with OpenDNS and now have their stats as well.

The only trade off has been in "concurrent sessions" where the Zywall supports only 10,000. There is a fix here, though, involving reducing the timeout-time for sessions so old ones don't hang around.

Why do you need more than 10000 simultaneous sessions?

I'm thinking I shouldn't if I've got the router set up properly. That Zywall has a bit of a learning curve to it. Anyway, I had a torrent which completed and hours later I still had 10000 sessions full and basically no access to the internet as a result. There's no "clear dead sessions" button. It seemed like a bug to me, as the "session monitor" showed 40-50 active sessions, and the "dashboard" showed 10000. (This torrent certainly didn't connect to more than 100-200 other clients.)

So I ran into a bug either in my bittorrent client (Synology Download Station) or in the router, or maybe more likely, a misconfiguration.

As I mentioned, I shortened the timeout time on tcp-established from 2.5 hours to 15 minutes and I haven't seen more than 100 active sessions since.
