Handling MobiLink server errors with .NET

When scanning the log is not sufficient, you can monitor your applications programmatically. For example, you can send messages of a certain type in an email.

You can write methods that are passed a class representing every error or warning message that is printed to the log. This may help you monitor and audit a MobiLink synchronization server.

The following code installs a Listener for all error messages and prints the information to a StreamWriter.

class TestLogListener {
    public TestLogListener( StreamWriter output_file  )
    {
        _output_file    = output_file;
    }
    public void errCallback( ServerContext sc, LogMessage lm )
    {
        string type;
        string user;
        if( lm.Type==LogMessage.MessageType.ERROR ) {
            type = "ERROR";
        } else if( lm.Type==LogMessage.MessageType.WARNING ) {
            type = "WARNING";
        } else {
            type = "INVALID TYPE!!";
        }
        if( lm.User == null ) {
            user = "null";
        } else {
            user = lm.User;
        }

        _output_file.WriteLine( "Caught msg type=" + type +
                                        " user=" + user +
                                        " text=" + lm.Text );
        _output_file.Flush();
    }
    StreamWriter    _output_file;
}

// Two lines that registers the TestLogListener Call this code
// from anywhere that has access to the ServerContext such as
// a class constructor or synchronization script.
// ServerContext serv_context;
TestLogListener etll = new TestLogListener(log_listener_file);
serv_context.ErrorListener += new LogCallback(etll.errCallback);
