我對Apache Storm很陌生並且一直試圖用卡夫卡的三叉戟拓撲結構，即TransactionalTridentKafkaSpout。除了Storm UI之外，所有的工作都很好。即使我沒有向我的主題提供任何數據，Storm UI仍然顯示無效的發射/傳輸值。即使主題中沒有數據，計數也會繼續增加。我試着刪除存儲在飼養員，風暴，卡夫卡的數據/日誌和重建卡夫卡主題和還建立風暴UI不正確的值和毛細管工具
topology.stats.sample.rate: 1.0
，但仍是問題仍然存在。
而且我還遇到了一個名爲Capillary的工具來監測風暴集羣。 我使用下面的特性
capillary.zookeepers="192.168.125.20:2181"
capillary.kafka.zkroot="192.168.125.20:/home/storm/kafka_2.11-0.8.2.0"
capillary.storm.zkroot="192.168.125.20:/home/storm/apache-storm-0.9.3"
我在這裏用卡夫卡的嵌入式飼養員。 即使這不起作用得到下面的例外。

任何一方面的幫助都很棒。提前致謝。

有沒有使用毛細管，但它看起來像在自己的源代碼一些錯誤的配置file.looking請問你的conf /路由文件看起來？ – user2720864
@ user2720864感謝您的回覆。我在我的問題中更新了我的配置設置。 – DMA
我相信這是用毛細管打動的東西。可能值得看看https://github.com/keenlabs/capillary/issues/5 – user2720864
