[script] Current Download/Upload WAN speed

[berez]

Hi,

is there possible to get information about current Download/Upload WAN speed? I would use bash script.

 

[ColinTaylor]

Probably. What sort of information do you want exactly?

 

[berez]

This speed value, or other similar current speed value...

is there possible to get information about current Download/Upload WAN speed? I would use bash script.

For download speed testing

curl  http://proof.ovh.net/files/100Mb.dat -w "%{time_connect},%{time_total},%{speed_download},%{http_code},%{size_download},%{url_effective}\n" -o /dev/null

and while the above is useful when run interactively, you can suppress the progress indicator to have only the '.csv' result line returned for piping/parsing out to a file for later analysis using scripting:

curl  -s http://proof.ovh.net/files/100Mb.dat -w "%{time_connect},%{time_total},%{speed_download},%{http_code},%{size_download},%{url_effective}\n" -o /dev/null

If you choose an appropriate Upload test site then the same technique can be used for Upload speed testing

I want get current speed-stats. No possible speed. Example: if my PC #1 downoads current 1mbps and second PC is downloading now 2mbps then value have to shows 3mbps as current download speed from WAN.

Speed is a function of time. So you have to decide what time period you are measuring, 1 millisecond, 1 second, 10 seconds, etc.

This command will give you the total number of bytes downloaded and uploaded at that point in time. If you wait for your desired sampling period (say 1 second) and issue the command again you can subtract one from the other giving you the rate.

ifconfig $(nvram get wan0_ifname) | grep "RX bytes" | awk -F[:\(] '{print $2 $4}'

Thanks - great solution.

What is the best way to "transfer" these values to another debian-based device (rapsberry pi)?

I see two solutions
1. Install mosquito service on the router, and then "publish" (by mosquitto_pub command) values to rapsberry pi.

or

2. Create script on rapsberry pi, script will do:
- logon to router by ssh
- execute @ColinTaylor command


maybe any other ideas?

Probably easier to use SNMP if you need this data on another device. Note that the RX+TX number on WAN interface (br0) would wrap after 4GB because Broadcom/Asus is funny that way.

 

[ColinTaylor]

I'd never heard of mosquito so can't comment on that.

I do something similar with QoS bandwidth data. I have a script that runs continuously on the router. Every 2 seconds it collects the data and appends it to a file together with a timestamp. Then I have another process that periodically runs on a Centos server that logs into the router with FTP and transfers the file. The file is fed into an RRD database and displayed as a graph on a web page.

EDIT: @kfp suggestion is probably a better solution, although it's not appropriate in my specific situation .

Whatever solution you choose should ultimately by driven by the data; frequency, format, accuracy, resilience, etc.
