# Svadilfari

A logger backend for sending logs directly to Grafana Loki.

## Installation

The package can be installed by adding `svadilfari` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:svadilfari, "~> 0.1"}

  ]

end

# Also make sure it starts before :logger because logger uses it now

def application do

  [

    ...

    extra_applications: [..., :svadilfari, :logger, ...]

    ...

  ]

```

Configure some parameters:

```elixir

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

# This setting is needed because Loki will complain if timestamps are too much off,

# and Logger sends timestamps without time zone information.

config :logger, utc_log: true

config :logger, :svadilfari,

  metadata: [:user_id, :bogons],

  max_buffer: 10,

  client: [

    url: "http://localhost:3100",

    opts: [

      org_id: "tenant1"

    ]

  ],

  labels: [

    {"service", "svadilfari"},

    {"env", "dev"}

  ]

```

and start sending logs to Loki!
