Enabling multiple daemons for high-volume data


These instructions apply to single-host Unravel deployments only; for multi-host deployments, please contact Unravel Support.


Run the <Unravel/installation/directory>/manager config worker --help to view the commands menu for scaling up daemons for high-volume data.

You increase the daemons only for the following daemons:

  • event_worker

  • metric_analyzer

  • spark_worker

  • unravel_sensor

  • yarn_jc_worker

  1. Stop Unravel.

    <Unravel/installation/directory>/manager stop
  2. Check the list of workers that are already customized.

    <Unravel/installation/directory>/manager config worker show
  3. Set the number of processes for a service type.

    <Unravel/installation/directory>/manager config worker count SERVICE_TYPE NUMBER

    In the following example, you add more event workers by setting 4 processes that are event_worker_1 to event_worker_4:

    <Unravel/installation/directory>/manager config worker count event_worker 4
  4. Apply the changes.

    <Unravel/installation/directory>/manager apply
  5. Start Unravel.

    <Unravel/installation/directory>/manager start
