The Configuration Management provides the operator options to configure the properties/templates of A10 Controller components such as Welcome Email template for the new users, Log level settings, Root Provider admins, Lightning ADC Images, and the Certificate configuration. These configurations can be configured via dashboard or can be configured via APIs.
