Hi R.RAMPRASAD I try to answer your questions and hope that will help you.

Storm UI keep track of tuple emit/ack/fail count of spout/bolt. For more detail information you can turn on topology debug mode and worker will log every tuple. > > 5.

Your can refer to the storm documentation site: http://storm.incubator.apache.org/documentation/Implementation-docs.html -- Best Regards! 肖康(Kang Xiao,<[email protected] (mailto:[email protected])>) Distributed Software Engineer 在 2014年2月22日 星期六，14:51，Ramprasad Ranganathan 写道： > Hi, > > I am beginner in Storm.I am trying to understand the processing flow of > storm by following questions. > > 1.
