Lager Scribe backend

====================

Lager backend for [facebook's scribe](https://github.com/facebook/scribe). This is a backend for the [Lager Erlang logging framework](https://github.com/basho/lager).

### Configuration

You can pass the backend the following configuration (shown are the defaults):

```erlang

    {lager, [

      {handlers, [

        {lager_scribe_backend, [

          {level,            debug},

          {formatter,        lager_default_formatter},

          {formatter_config, []},

          {category,         undefined}

          {scribe_host,      "localhost"},

          {scribe_port,      1463},

          {pool_size,        [{size, 5}, {max_overflow, 10}]}

        ]}

      ]}

    ]}

```

### Scribe log entry category

To define custom scribe category for message one should implement own `category` module like this

```erlang

-module(myapp_lagger_scribe_category).

-behaviour(lager_scribe_category).

-export([category/1]).

category(Message) ->

    Severity = lager_msg:severity(Message),

    log_category(Severity).

log_category(error) -> "myapp-error";

log_category(_)     -> "myapp-info".

```

by defalt category would be `lager.`

### Poolboy integration

`lager_scribe_backend` uses process pool to send log messages to scribe. You can tune pool size in handler config. To know more about `max_overflow` option see [poolboy documentation](https://github.com/devinus/poolboy/blob/master/README.md#options)
