The only benefit speedtest has over other testing solutions (iperf, ftp)
is the existence of a ton of test servers. This means you can measure
(with best effort) available bandwidth between two points on the
internet (not your own network).
@STR: you can set up multiple probes and assign each one a different
offset so that you'll be sure the speedtest don't overlap and you don't
get slowed down by your uplink. Or specify the offset as part of the
host configuration (should work)

Hi!
If you have the ability to set up an dedicated test server I have
implemented an speed test for smokeping using nuttcp. Given that
nuttcp has more granular controll than speedtest.net you can do things
as create traffic streams for different traffic classes. For example
using udp to model SIP RTP, and throughput in high vs low priority
que.
The code is written for my own test purposes using my fairly limited
skill set so the code won't impress anybody. But if you have the
need, just contact me and I'll happily share.

Adrian,
It’s probably not enough of a sample size but if I just use 1 speedtest host
local to my city it shows the correct download speeds as I’d suspected.
This is evidenced by
http://wrt.asuscomm.com:81/smokeping/?target=Speedtest.Download.Tata_Technologies_Pune_Down
Looking at the Last 30 hours or Last 10 day graphs you can see where I
configured it to use just 1 host, then multihost, then back down to 1 host.
It could well be a speedtest.net issue with me hitting multiple servers and
they just not liking it.
Obviously the probe is reporting the correct values given to it by
speedtest-cli
Also any idea why the Y axis pulls “var units” from Smokeping.pm unlike
other multihost graphs?
Could these 2 issues be related?

“var units” is being pulled from line 892 in smokeping.pm
# if there are multiple units ... lets say so ...
if ($ProbeUnit ne $probe->ProbeUnit()){
$ProbeUnit = 'var units';
}
Any idea why only Speedtest multihost graphs pull that value?

I don't know why the measurement unit is not correct for multigraphs, but I
have tested the plugin and it can correctly display bandwidths of hundreds
of Mbps. Note, that speedtest-cli values are generally lower than what you
get from the speedtest web interface. Also, they will likely vary in time.

Thanks for a great probe!
I think there may be some minor issues still.
I don’t see any of the hosts show me more than 2Mb/s download, which is
incorrect as it should be close to 7.5 – 8 Mb/s
I understand the upload tests might be skewed given the low upload ADSL has.
Some more testing with just the speedtest node closest to me should shed
some light on this.
On the speedtest multihost graphs, only on the main overview page, the
legend for Y axis displays “var units” instead of “bps”.
Example: https://dl.dropboxusercontent.com/u/314525/MultiHost_mini.png
When I open the multihost page, the Y axis is correctly called “bps”.
Example: https://dl.dropboxusercontent.com/u/314525/MultiHost_last_10800.png
Why would multihost only change it for speedtest, none of the other
multihost graphs display this issue?

Sweet, Thanks for your contribution!

Of course, it’s been so long I touched Smokeping configurations I forgot
multihost and I use it for DNS!
So get and choose servers in your city/country list from speedtest-cli:
speedtest-cli --list|grep -w Germany
