Hi Kevin, You can attach metrics consumer to log additional informations for that topology like disruptor queue metrics, __skipped-max-spout for spout, and etc. Please refer https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/metric/LoggingMetricsConsumer.java to how to set up.
Please note that it may affect whole throughput (I guess it would be relatively small) so you may want to attach when only testing / debugging performance issue.
