By: Bayo Erinle

Overview of this book

JMeter is a Java application designed to load and test performance for web application. JMeter extends to improve the functioning of various other static and dynamic resources. This book is a great starting point to learn about JMeter. It covers the new features introduced with JMeter 3 and enables you to dive deep into the new techniques needed for measuring your website performance. The book starts with the basics of performance testing and guides you through recording your first test scenario, before diving deeper into JMeter. You will also learn how to configure JMeter and browsers to help record test plans. Moving on, you will learn how to capture form submission in JMeter, dive into managing sessions with JMeter and see how to leverage some of the components provided by JMeter to handle web application HTTP sessions. You will also learn how JMeter can help monitor tests in real-time. Further, you will go in depth into distributed testing and see how to leverage the capabilities of JMeter to accomplish this. You will get acquainted with some tips and best practices with regard to performance testing. By the end of the book, you will have learned how to take full advantage of the real power behind Apache JMeter.

Summary


In this chapter, we went through the details of how to capture and monitor tests in real time using some wonderful open source tools (InfluxDB and Grafana). We learned how to set up the InfluxDB database and configure JMeter to write our test metrics to it. We then explored how to use Grafana to visualize the results of our overall tests and how to drill down into specific requests at will. We also highlighted some of the system metrics you can capture to give you a better insight into bottlenecks, errors, and latency.

We have barely scratched the surface of these tools, but we hope we have covered enough to whet your appetite to explore more.

In the next chapter, we will dive deep into distributed testing and see how to leverage the capabilities of JMeter to accomplish this.
