Blacklist Ports

Use the blacklisted_ports parameter in the the agent configuration file to block network traffic and metrics from unnecessary network ports.

Note: 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.
