OpentelemetryOban

OpentelemetryOban uses telemetry handlers to create OpenTelemetry spans from Oban events.

Installation

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

def deps do
  [
    {:opentelemetry_oban, "~> 1.0"}
  ]
end

In your application start:

    def start(_type, _args) do
      OpentelemetryOban.setup()

      # ...
    end

Usage

By default a new trace is automatically started when a job is processed.

To also record a span when a job is created and to link traces together Oban.insert/2 has to be replaced by OpentelemetryOban.insert/2.

Before:

  %{id: 1, in_the: "business", of_doing: "business"}
  |> MyApp.Business.new()
  |> Oban.insert()

After:

  %{id: 1, in_the: "business", of_doing: "business"}
  |> MyApp.Business.new()
  |> OpentelemetryOban.insert()

Oban also supports inserting jobs using Oban.insert/4 and Oban.insert_all/4. These are currently not supported by OpentelemetryOban and are just proxied through to Oban.
