#  Gelato
An opinionated [logger backend](https://hexdocs.pm/logger/Logger.html#module-backends) helper library to log events with [`telemetry`](https://hexdocs.pm/telemetry) attached.
## Installation
```elixir
def deps do
[
{:gelato, "~> 0.2"}
]
end
```
## Usage
```elixir
# sends the single event with attached process info to Elastic server
Logger.info "users", name: "John", reference: "U-123456789"
# sends the “in” and “out” events to Elastic server, with some collected
# stats in “out” events; discards process info
Gelato.bench :info, "users", name: "John", reference: "U-123456789", process_info: "N/A"
```
Besides `Gelato.bench/4`, this library provides `Gelato.defdelegatelog/2` macro
that might be used for mastering interfaces to internal codepieces _featured by telemetry log_.
Once delegated, the function is being wrapped into `Gelato.bench/4` call.
The following example is taken from tests.
```elixir
defmodule Gelato.Test.DDL.Helper do
@moduledoc false
def yo(arg), do: {:ok, arg}
end
defmodule Gelato.Test.DDL.Test do
@moduledoc false
use Gelato
defdelegatelog yo_test(arg),
to: Gelato.Test.DDL.Helper,
as: :yo,
level: :warn,
tag: "app",
entity: :ddl
end
```
