An InfluxDB writer for Elixir

Fluxter

Fluxter is an InfluxDB writer for Elixir. It uses InfluxDB's line protocol over UDP.

Note: if you're using Erlang 19 or greater, you need Fluxter 0.4.0 or greater otherwise metrics reporting will (silently) not work because of network driver changes happened between Erlang 18 and Erlang 19.

Installation

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

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

defp deps() do
  [{:fluxter, "~> 0.4"}]
end

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

Usage

A module that uses Fluxter becomes an InfluxDB connection pool:

defmodule MyApp.Fluxter do
  use Fluxter
end

Each Fluxter pool provides a start_link/0 function that starts the pool and connects to InfluxDB; this function needs to be invoked before the pool can be used. Usually, you won't call start_link/0 directly as you'll want to use a Fluxter pool as part of your application's 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

Once the Fluxter pool is started, its write/2,3 and measure/2,3,4 functions can successfully be used to send points to the data store.
