In the first two chapters, we primarily focused on how to set up the local mode and the distributed mode of Storm cluster. You also learned how we can develop and deploy the topology on a Storm cluster.

In this chapter, we mainly concentrated on different ways of monitoring the Storm cluster. We began by starting the Storm UI and covered how we can monitor the topology using the Storm UI. We also walked through the Nimbus thrift client and covered sample examples that demonstrate how we can collect the Storm cluster's details using the Nimbus thrift client.
