# Fluxter
[](https://travis-ci.org/lexmag/fluxter)
[](https://hex.pm/packages/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:
```elixir
def application() do
[applications: [:fluxter]]
end
defp deps() do
[{:fluxter, "~> 0.7"}]
end
```
Then run `mix deps.get` in your shell to fetch the dependencies.
## Usage
A module that uses Fluxter becomes an InfluxDB connection pool:
```elixir
defmodule MyApp.Fluxter do
use Fluxter
end
```
Each Fluxter pool provides a `start_link/1` function that starts the pool and connects to InfluxDB; this function needs to be invoked before the pool can be used.
Typically, you won't call `start_link/1` directly as you'll want to
add a Fluxter pool to your application's supervision tree.
For this use case, pools provide a `child_spec/1` function:
```elixir
def start(_type, _args) do
children = [
MyApp.Fluxter.child_spec(),
#...
]
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.
Much more information can be found in the [documentation](http://hexdocs.pm/fluxter).
