Fluxter

Fluxter is an InfluxDB writer for Elixir, it uses line protocol over UDP.

Installation

Add Fluxter as a dependency to your mix.exs file:

def application() do
  [applications: [:fluxter]]
end

defp deps() do
  [{:fluxter, "~> 0.1"}]
end

Then run mix deps.get in your shell to fetch the dependencies.

Usage

A module that uses Fluxter represents connection pool:

defmodule MyApp.Fluxter do
  use Fluxter
end

Each Fluxter pool has a start_link/0 function that needs to be invoked before using it. In general, this function is not called directly, but used as part of your application supervision tree, for example:

def start(_type, _args) do
  import Supervisor.Spec

  children = [
    supervisor(MyApp.Fluxter, []),
    #...
  ]
  Supervisor.start_link(children, strategy: :one_for_one)
end

Thereafter, the write/2,3 and measure/2,3,4 functions will be successfully sending points to the datastore.

Configuration

Fluxter could be configured globally with:

config :fluxter,
  prefix: "my_app",
  host: "metrics.tld",
  port: 1122

and on a per module basis as well:

config :fluxter, MyApp.Fluxter,
  pool_size: 10,
  port: 2233

The defaults are:

• prefix: nil
• host: "127.0.0.1"
• port: 8092
• pool_size: 5
