      • allScopes

        public boolean allScopes()
        Description copied from interface: LogCorrelation

        Otherwise the default is to only insert at entry points, such as incoming HTTP requests.

        Specified by:
        allScopes in interface LogCorrelation
        Returns:
        whether to check log correlation for all context scopes

      • key

        public java.lang.String key()
        Description copied from interface: LogCorrelation
        MDC key used for this log correlation.
        Specified by:
        key in interface LogCorrelation
        Returns:
        MDC key for this correlation

      • value

        public java.lang.String value()
        Description copied from interface: LogCorrelation

      • normalize

        public boolean normalize()
        Description copied from interface: LogCorrelation
        Should the key name for this correlation identifier be normalized in MDC?

        For example, if MDC contains the key "correlation-id", but the key() is configured as "Correlation-ID", enabling this setting will make Cinnamon scan the MDC keys and normalize incorrect casing when it occurs.

        Specified by:
        normalize in interface LogCorrelation
        Returns:
        true if the correlation identifier key name should be normalised
