CloudWatch

cloud_watch is a logger backend for Elixir that puts log events on Amazon CloudWatch.

Installation

Add cloud_watch to your list of dependencies in mix.exs:

def deps do
  [{:cloud_watch, "~> 0.1.0"}]
end

Ensure cloud_watch is started before your application:

def application do
  [applications: [:cloud_watch]]
end

Configuration

Add the backend to config.exs:

config :logger,
  backends: [:console, CloudWatch]

Configure the following example to suit your needs:

config :logger, CloudWatch,
  access_key_id: "AKIAIOSFODNN7EXAMPLE",
  secret_access_key: "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
  region: "eu-west-1",
  endpoint: "amazonaws.com",
  log_group_name: "api",
  log_stream_name: "production",
  max_buffer_size: 10_485

The endpoint may be omitted from the configuration and will default to amazonaws.com. The max_buffer_size controls when cloud_watch will flush the buffer in bytes. You may specify anything up to a maximum of 1,048,576 bytes. If omitted, it will default to 10,485 bytes.
