Ecto integration for [Prometheus.ex](https://github.com/deadtrickster/prometheus.ex)

 - IRC: #elixir-lang on Freenode;
 - [Slack](https://elixir-slackin.herokuapp.com/): #prometheus channel - [Browser](https://elixir-lang.slack.com/messages/prometheus) or App(slack://elixir-lang.slack.com/messages/prometheus).

## Quickstart

1. Define your instrumenter:

    ```elixir
    defmodule MyApp.Repo.Instrumenter do
      use Prometheus.EctoInstrumenter
    end
    ```

2. Call `MyApp.Repo.Instrumenter.setup/0` when application starts (e.g. supervisor setup):

    ```elixir
    MyApp.Repo.Instrumenter.setup()
    ```

3. Add `MyApp.Repo.Instrumenter` to Repo loggers list:

    ```elixir
    config :myapp, MyApp.Repo,
      loggers: [MyApp.Repo.Instrumenter, Ecto.LogEntry]
      # ...
    ```
