Blacklist Ports

Use the blacklisted_ports parameter in the agent configuration file to block network traffic and metrics from unnecessary network ports. Note that Port 53 (DNS) is always blacklisted.

  1. Access the agent configuration file, using one of the options listed.

  2. Add blacklisted_ports with desired port numbers.

    Example (YAML):

    blacklisted_ports:

    - 6443

    - 6379

  3. Restart the agent (if editing dragent.yaml file directly), using either the service dragent restart or docker restart sysdig-agent command as appropriate.
