Should be an easy task with process engine of 6.0 and upwards. Be aware that the shown example uses non-public API and that it can change without any notice.

The following code show a custom engine execution listener that logs the data and process element PID of every element that is executed:

public class ExecListener {

    public static void install()
    {
        IBpmEngine engine = DiCore.getGlobalInjector().getInstance(IBpmEngine.class);
        engine.getHistory().addElementHistoryListener(new LoggingListener(Ivy.log()));
    }

    private static class LoggingListener implements IElementHistoryListener
    {
        private final Logger logger;

        public LoggingListener(Logger logger) {
            this.logger = logger;
        }

        @Override
        public void elementExecutionHistoryAdded(IElementExecutionHistory executionHistory) {
            PID pid = executionHistory.getElementRequestHistory().getElementHistory().getProcessElementId();
            logger.info("executing element pid: "+pid);

            Object in = executionHistory.getData().getAttributeValue("in");
            if (in instanceof Data)
            {
                Data data = (Data)in;
                logger.info(data);
            }
        }
    }
}
