Filter roles

Locate the cassandra.yaml configuration file. The location of this file depends on your installation type.

Package installations
Tarball installations

/etc/hcd/cassandra/cassandra.yaml

INSTALLATION_LOCATION/resources/cassandra/conf/cassandra.yaml

Replace INSTALLATION_LOCATION with the path where you extracted the HCD tarball.

Set up activity tracking of specific login roles in the audit_logging_options section of the cassandra.yaml.

audit_logging_options:
    enabled: true
    logger:
      - class_name: LOGGER_NAME
#    included_categories:
#    excluded_categories:
#    included_keyspaces:
#    excluded_keyspaces:
#    included_roles:
#    excluded_roles:

where LOGGER_NAME is SLF4JAuditWriter or CassandraAuditWriter.

By default, both roles parameters are commented out and therefore events are captured for all roles. Use only one of the following parameters to limit the roles whose activity is tracked:

included_roles: Includes only matching roles; excludes all others.
excluded_roles: Excludes matching roles; includes all others.

Match roles using a comma-separated list of names.

Example

Events of all roles except for hcd_admin and jim are captured.

audit_logging_options:
    enabled: true
    logger:
      - class_name: CassandraAuditWriter
#    included_categories:
#    excluded_categories:
#    included_keyspaces:
#    excluded_keyspaces:
#    included_roles:
    excluded_roles: hcd_admin, jim
