tcp-throughput-proxy

Proxy that allows you to monitor how much incoming trafic it is receiving.

npm install -g tcp-throughput-proxy

Usage

# start a proxy listening on port 10000 proxing to localhost:20000
tcp-throughput-proxy --from 10000 --to localhost:20000

Optionally if you only want to monitor throughput and not proxy anywhere

# just monitor throughput
tcp-throughput-proxy --from 10000

Then to start monitoring throughput connect to the monitor server. Per default the monitor is listening on the from port + 1. To connect to it simply open a tcp connection to the monitor server

# attach to the monitor server
nc localhost 10001

The monitor server should start printing out stats in the following format

0 open connections
Receiving 0 b/s

If you open up another tcp connection to the proxy server and start writing data you should see the receive speed go up. For example to write a bunch of random data to it do

# pipe a bunch of random data to the proxy
cat /dev/random | nc localhost 10000

After executing the above you should see receive speed in the monitor connection go up
