@obazoud Could you explain how this works a little more to me? I don't know anything about graphite and I'd like to learn.

Graphite has 3 individual components

• Carbon: a daemon that listens incoming data (metric) and store numeric time-series data in whisper files
• Graphite-web: render graphs in browser
• Whisper: is a fixed-size database
  Graphite is based on "push" not "pull".

A simple way to send metrics (TCP or UDP):

echo "<metric path> <metric value> <metric timestamp>" | nc $SERVER $PORT
echo "myserver.load.1m 4 `date +%s`" | nc 127.0.0.1 2003
echo "myserver.load.5m 4 `date +%s`" | nc 127.0.0.1 2003
echo "myserver.load.15m 4 `date +%s`" | nc 127.0.0.1 2003

metric path: a metric path that be renderer as a tree

.
└── myserver
    └── load
        └── 1m
        └── 5m
        └── 15m

metric value: an integer or a float
metric timestamp: a UNIX timestamp

Graphite (web) are some very nice features:

• easy to add few metrics in a graph, create dashboard
• apply fonction like : percent, average, derivative, integral, nPercentile, timeShift (my favorite:)), ...
• export data as json
• export data as image

My reactor is to send metric based on data event to Graphite.

• A best practice is to prefix metric by environment (or that ever you want) what why I add this option.
• metric name will be ... and I replace '.' by '_' in host and service

For example with the following event and prefix = "production."

{ host: 'app.server.com',
  service: 'app.server2/health/heartbeat',
  state: 'up',
  time: 1360523052932,
  description: 'No description',
  tags: [],
  metric: 1,
  ttl: 3000 }

metric name will be "production.app_server_com.app_server.health.heartbeat.up"
metric value is 1
metric timestamp is 1360523052932

@obazoud Why the string replacement in metric names?

@indexzero I replace '.' by '_' to have a better layout in, Graphite.
Graphite creates a directory each time it finds a '.'
I create a metric by state.

Without replacement:

With replacement:

@obazoud do you mind posting your godot server on a gist, I need to implement a simple godot - graphite bridge and don't want to reinvent the wheel.

Cherry-picked. Thanks!

@mwawrusch You have an example https://github.com/nodejitsu/godot/blob/master/lib/godot/reactor/graphite.js#L8

You can find a lot of stuff (still in progress) about gobot at https://github.com/organizations/godot-plugins
including Graphite Producer at https://github.com/godot-plugins/godot-graphite

Awesome, thank you.
