carbon daemon that accepts and stores metrics
whisper database where metrics are kept
web app that reads metrics and processes them using a comprehensive list of supported functions

Every component exposes several APIs that are used by other components. All of them are written in Python.

Two more components are often used together with Graphite:

StatsD — a Node.js app that accepts metrics and aggregates them before submitting to carbon;
Grafana — web dashboard for Graphite (and other backends)

So what?

This set of images replaces original carbon daemon and StatsD aggregation daemon with other compatible components to improve performance and throughput.

Grafana 3 is also included.

Included images

Component	Version
go-carbon	`v0.7.2`	Drop-in replacement for original `carbon` daemon, written in Go
Brubeck	`5d139a4`	Easy replacement for `StatsD`, written in C
Graphite API	`latest`	A piece of original `Graphite Web` component with less features
Grafana	`v3.1.0-beta1`	Beautiful dashboard for all of that

Building

Make sure Docker and Docker Compose are installed.

$ make graphite fast

Re-building

$ make graphite fast again

Starting

$ make run

Using

Open Grafana dashboard at http://[docker-host]:3000/, sign in as admin/admin
Create new data source of type Graphite that points to http://graphite-api:8000
Create a new chart with a test metric (test.ping in this example)
Start sending metrics to StatsD-compatible endpoint
Metrics should show up on Grafana dashboard

You can send metrics right from terminal:

# 1000 times
# Send "test.ping:1|C\n"
# Verbose, Using UDP, Timeout 1s
# To StatsD port on Docker
$ for i in {1..1000}; do echo "test.ping:1|C" | nc -v -u -w1 `docker-machine ip` 8126; done
