 - `process_alive_threshold`: how long to wait until a process is considered dead after its last heartbeat—defaults to 5 minutes.
 - `shutdown_timeout`: time the supervisor will wait since it sent the `TERM` signal to its supervised processes before sending a `QUIT` version to them requesting immediate termination—defaults to 5 seconds.
 - `silence_polling`: whether to silence Active Record logs emitted when polling for both workers and dispatchers—defaults to `true`.
+- `silence_heartbeats`: whether to silence Active Record logs emitted for heartbeats for both workers and dispatchers—defaults to `false`.
 - `supervisor_pidfile`: path to a pidfile that the supervisor will create when booting to prevent running more than one supervisor in the same host, or in case you want to use it for a health check. It's `nil` by default.
 - `preserve_finished_jobs`: whether to keep finished jobs in the `solid_queue_jobs` table—defaults to `true`.
 - `clear_finished_jobs_after`: period to keep finished jobs around, in case `preserve_finished_jobs` is true—defaults to 1 day. **Note:** Right now, there's no automatic cleanup of finished jobs. You'd need to do this by periodically invoking `SolidQueue::Job.clear_finished_in_batches`, but this will happen automatically in the near future.
