The Log Connector is very different from other connectors as it does not have any idea of source/target system. You can use the information provided here to know further about this.
This connector was written exclusively to give you an alternative access to the IBM Security Directory Integrator logging features; see "Logging and debugging" in the Installing and Administering.
The Log Connector enables you to use logging utilities in a simpler way, requiring less scripting. The connector can be inserted at any point in the AssemblyLine and enabled/disabled dynamically. Prior to the introduction of this connector you would have to add script code that invoked the AssemblyLine's log object. Using this log object would add log messages to all loggers associated with the AssemblyLine's log object. Similarly, adding a logger to the AssemblyLine (using the AssemblyLine logging configuration screen) would also merge IBM Security Directory Integrator's internal logging to the log output channel causing the log to fill up with possibly unwanted log messages. The Log Connector gives you explicit control of all messages written to the log channel.
This Connector supports AddOnly mode only.
