问题描述
我对Storm-UI统计信息感到困惑.
I am confused by the Storm-UI statistics.
例如:
拓扑统计显示了6900万
kafka-spout 显示数量为3400万
kafka-spout shows a number of 34 million
__ acker 为1700万
es-bolt 也显示1700万
我的拓扑结构是kafka-spout-> es-bolt，我不确定上面的数字是怎么累加的?
My toplogy is kafka-spout --> es-bolt and I am not sure how the numbers above add up?
如果Kafka-spout仅排放3400万，为什么拓扑统计数据显示6900万?
If Kafka-spout is emitting only 34 million, why do topology stats show 69 million?
如果卡夫卡喷口再次排放了3400万，为什么电喷说1700万?
And again if Kafka-spout emitted 34 million, why does es-bolt say 17 million?
我看到元组的样式从上到下减半，但是不确定我为什么会这样吗?是因为发-或心跳过大?
I see a pattern of tuples being halved from top-to-down, but not sure I understand why? Is it because of ack-tuples or heart-beat bolts?
它们总是上游喷嘴的一半吗?
Are they always half of the upstream spout?
推荐答案
您可以关闭系统统计信息，然后数字才有意义."Storm UI统计信息"页面底部有一个按钮.
You can turn off system stats, then numbers will make sense.There's button on the bottom of Storm UI stats page.
