Logger

Loggers let you control the log messages for CA EEM SDK. To enable a logger, remove the comment strings from their respective code.

A logger contains the following parameters:

• logger name

  Specifies the name of a logger.

• additivity

  Specifies if the log messages are duplicated in the SDK log file.

  Value: [true|false]

  Default: false

• level value

  Specifies log level of a logger.

  Value: [Trace|Debug|Info|Warn|Error|Fatal|Off]

  The following are the log levels, in the order of their precedence:

  Note: Higher the log level, lesser is the performance of CA EEM.

  • Trace

    Indicates low level debugging. It contains control flow and passes arguments.

  • Debug

    Indicates messages used for problem diagnosis. It contains contextual information.

  • Info

    Indicates contextual information that traces execution at a coarse-grained level in a production environment.

  • Warn

    Indicates a potential problem in the system. For example, if the message category corresponds to security, a warning message must display if a dictionary attack is detected.

  • Error

    Indicates a serious problem in the system. The problem is non-recoverable and requires manual intervention.

  • Off

    Indicates the absence of logging.

  Note: The log level of the default SDK appender must be Error.

Example: Performance Logger

<logger name="Perform" additivity="false">

<level value="trace"/>
<appender-ref ref="Performance" />

</logger>
