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 Ganglia

Ganglia is a monitoring tool that is used to collect the metrics of different types of processes that run on a cluster. In most applications, Ganglia is used as the centralized monitoring tool to display the metrics of all the processes that run on a cluster. Hence, it is essential that you enable the monitoring of the Storm cluster through Ganglia.

Ganglia has three important components:

  • Gmond: This is a monitoring daemon of Ganglia that collects the metrics of nodes and sends this information to the Gmetad server. To collect the metrics of each Storm node, you will need to install the Gmond daemon on each of them.
  • Gmetad: This gathers the metrics from all the Gmond nodes and stores them in the round-robin database.
  • Ganglia web interface: This displays the metrics information in a graphical form.

Storm doesn't have built-in support to monitor the Storm cluster using Ganglia. However, with JMXTrans, you can enable Storm monitoring using Ganglia. The...
