Technical requirements
To follow along with the sample Logstash configurations for real-world data-processing use cases, you will need access to a virtual machine with Logstash installed or the ability to run Logstash on your host machine, as shown in Chapter 2, Installing and Running the Elastic Stack.
The code for this chapter can be found on the GitHub repository for the book: https://github.com/PacktPublishing/Getting-Started-with-Elastic-Stack-8.0/tree/main/Chapter7.
