Mastering Apache Storm

By: Ankit Jain

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.

Monitoring the Storm cluster using JMX

This section will explain how we can monitor the Storm cluster using Java Management Extensions (JMX). The JMX is a set of specifications used to manage and monitor applications running in the JVM. We can collect or display Storm metrics, such as heap size, non-heap size, number of threads, number of loaded classes, heap and non-heap memory, virtual machine arguments, and managed objects on the JMX console. The following are the steps we need to perform to monitor the Storm cluster using JMX:

  1. We will need to add the following line in the storm.yaml file of each supervisor node to enable JMX on each of them:
supervisor.childopts: -verbose:gc -XX:+PrintGCTimeStamps - XX:+PrintGCDetails - - -   

Here, 12346 is the port number used to collect the supervisor JVM metrics through JMX.

  1. Add the following...
