Internet performance tracking

Postby nickk » Sat Nov 24, 2018 1:34 am

Work in progress tool to track the performance of the internet path between our CDN and your home:
https://my.hdhomerun.com/account/internet_stats.html

Information is shown when a viewing or recording of a HDHomeRun Premium TV channel has taken place going back 2 hours.

Float over the any point to see the value - displayed in the heading above the graph.

When things are healthy the two RTT lines should be about the same and the available bandwidth should be reasonable.
The occasional spike in RTT BBR is ok.

No graph lines: The graph needs at least two minutes of TV viewing to start to display - if you have just started watching give it a bit more time to gather data then refresh the page.

You need to go full screen or scroll right -- the graph does not auto-size to window... Also you may need to refresh to get the updated snapshot.

nice!

am guessing oak means the CDN is in oakland? or just name of the graphing util?
I assume time is UTC?
Whats the lag between use and the graph updating?

I ran 2 tuners (CNN and AMC) for about a minute - but the 2 RTT lines never increased, it seems to just indicate one channel, was expecting it to almost double?

Speaking of which - would be nice to see number of streams being consumed ;)

Blank page: this means there has been no HDHomeRun Premium TV access in the last 2 hours from the current IP address.

No graph lines: if the graph is wider than the window - scroll to the right. It can also mean it only has one minute of data and you need to give it a few more minutes of TV viewing.

"oak" indicates Oakland location. The datacenter is on the main trunk going up/down the West side of the country.

Yes, UTC time.

It samples every minute.

RTT min shouldn't change with 2 streams (hopefully).
RTT BBR should only increase if there is a last-mile bandwidth bottleneck.
Also give it a few more minutes to get data.

Ah - now I get what RTT is measuring...
cool - looks like Cox is getting the data through to me nicely :)

Lag... it needs two 1-minute samples to start to display. From there it has new data every minute if you refresh.

Shows three squiggly lines, none of which indicate any glitching I can see with my eyeballs in a live stream. Pixelation, video lag, video destruction, audio glitching all go unnoticed by the new 'toy'... or it indicates it's not my internet with the issue...

Eyeballing some of the numbers... which one of you has the 2.2Gbps 0.9ms path to our servers?

Obvious guess: whoever maintains your servers. It would make sense to connect an HDHR at the server location to sample the feed and use the old Telco cliche, "OK leaving here. The problem must be at the other end."

Correct. All this does it track internet issues.
