Overview of this book

Apache Storm is a real-time Big Data processing framework that processes large amounts of data reliably, guaranteeing that every message will be processed. Storm allows you to scale your data as it grows, making it an excellent platform to solve your big data problems. This extensive guide will help you understand right from the basics to the advanced topics of Storm. The book begins with a detailed introduction to real-time processing and where Storm fits in to solve these problems. You’ll get an understanding of deploying Storm on clusters by writing a basic Storm Hello World example. Next we’ll introduce you to Trident and you’ll get a clear understanding of how you can develop and deploy a trident topology. We cover topics such as monitoring, Storm Parallelism, scheduler and log processing, in a very easy to understand manner. You will also learn how to integrate Storm with other well-known Big Data technologies such as HBase, Redis, Kafka, and Hadoop to realize the full potential of Storm. With real-world examples and clear explanations, this book will ensure you will have a thorough mastery of Apache Storm. You will be able to use this knowledge to develop efficient, distributed real-time applications to cater to your business needs.

Cluster statistics using the Nimbus thrift client

This section covers how we can collect cluster details (similar to the details shown on the Storm UI page) using the Nimbus thrift client. Extracting/collecting information through the Nimbus thrift client allows us to visualize the data.

The Nimbus thrift API is very rich, and exposes all the necessary information required to monitor the Storm cluster.

Fetching information with Nimbus thrift

In this section, we will be creating a Java project that will contain classes that will perform the following operations using the Nimbus thrift client:

  • Collect the Nimbus configuration
  • Collect the supervisor statistics
  • Collect the topology statistics
  • Collect the spout statistics for a given topology
  • Collect the bolt statistics for a given topology
  • Kill the given topology

The following are the steps to fetch the cluster details using the Nimbus thrift client:

  1. Create a Maven project by using com.stormadvance as groupId and stormmonitoring as artifactId.
  2. Add the following...
