Getting Started with Logstash
Logstash is easy to set up and deploy. We're going to go through the basic steps of installing and configuring it. Then we'll try it out so we can see it at work. That will provide us with an overview of its basic set up, architecture, and importantly the pluggable model that Logstash uses to input, process and output events.
Installing Java
Logstash's principal prerequisite is Java and Logstash itself runs in a Java Virtual Machine or JVM. Logstash requires Java 8 or later! Let's start by installing Java. The fastest way to do this is via our distribution's packaging system, for example Yum in the Red Hat family or Debian and Ubuntu's Apt-Get.
