gostatsd

An implementation of Etsy's statsd in Go.

The project provides both a server called "gostatsd" which works much like Etsy's version, but also provides a library for developing customized servers.

Building the server

From the gostatsd/ directory run go build. The binary will be built in place and called gostatsd

Running the server

gostatsd -help gives a complete description of available options and their defaults.

Sending metrics

The server listens for UDP packets on the address given by the -l flag, aggregates them, then sends them to graphite server address given by the -g flag.

The format of each metric is:

<bucket name>:<value>|<type>\n

• <bucket name> is a string like abc.def.g, just like a graphite bucket name
• <value> is a string representation of a floating point number
• <type> is one of c, g, or ms for "counter", "gauge", and "timer" respectively.

A single packet can contain multiple metrics, each ending with a newline.

A simple way to test your installation or send metrics from a script is to use echo and the netcat utility nc:

echo 'abc.def.g:10|c' | nc -w1 -u localhost 8125

Monitoring

Currently you can get some basic idea of the status of the server by visiting the address given by the -c option with your web browser.

Using the library

In your source code:

import "github.com/kisielk/gostatsd/statsd"
