A default logger is instantiated when you create a communicator. The default logger writes its messages to the standard error output. The trace operation accepts a category parameter in addition to the error message; this allows you to separate trace output from different subsystems by sending the output through a filter.

You can obtain the logger that is attached to a communicator using the getLogger operation:

{zcode:slice}
module Ice {
    local interface Communicator {
        Logger getLogger();
        // ...
    };
};
{zcode}
