attach_default_logger(Logger.level()) :: :ok | {:error, :already_exists}

Attaches a default structured JSON Telemetry handler for logging.

This function attaches a handler that outputs logs with the following fields:

• args — a map of the job's raw arguments
• duration — the job's runtime duration, in the native time unit
• event — either :success or :failure depending on whether the job succeeded or errored
• queue — the job's queue
• source — always "oban"
• system_time — when the job started, in microseconds
• worker — the job's worker module

Examples

Attach a logger at the default :info level:

:ok = Oban.Telemetry.attach_default_logger()

Attach a logger at the :debug level:

:ok = Oban.Telemetry.attach_default_logger(:debug)
