proxy

The proxy uses consistent hashing to map statsd metric names to statsd instances.

Project Status

This code has not been tested in a production environemnt. I wrote this while I was learning golang as an experiment. I wanted to have a simple networking app that I could compare with a similar Node.js project. You can find the Node.js version at https://github.com/etsy/statsd/blob/master/proxy.js.

Install

$ go get github.com/dmcaulay/proxy

Test

$ godep go test

Configuration

The configuration files are stored within the config directory and can be specified via the environment parameter.

$ proxy -e=production

The file format is json and you can find the production config at config/production.json

{
  "Nodes": [
    {"Host": "127.0.0.1", "Port": 8127},
    {"Host": "127.0.0.1", "Port": 8129},
    {"Host": "127.0.0.1", "Port": 8131}
  ],
  "UdpVersion": "udp4",
  "Host":  "0.0.0.0",
  "Port": 8125
}

The Nodes attribute specifies the statsd instances and the UdpVersion, Host and Port attributes specify the proxy configuration.

Run

$ godep go install
$ proxy
