Customize violation levels for policy rules

By default, NCM provides three violation levels for compliance reports. You can select one of these levels in rules to specify the alert level of the violation.

  • Level 1: Informational
  • Level 2: Warning
  • Level 3: Critical

You can customize the descriptor of the violation level to have a different meaning for the level.

  1. Click Settings > All Settings. If you are on the Compliance Policy Reports view, click NCM Settings in the top right of the view.
  2. In the Compliance Policy Report Management section, select Manage Violation Level.
  3. In the text field for the level that you are changing, replace the word describing that level.
  4. Click Submit.
