For short test runs `kafka-producer-performance` may not print any metrics at all. This is fixed by moving the final call to `printMetrics` just before closing the producer. Calling `printMetrics` after the producer is closed does nothing as the producer metrics are unregistered as part of the close. Signed-off-by: Adrian Preston <PRESTONA@uk.ibm.com>
