Logstash plays an extremely important role in any ELK-based data pipeline but is still considered as one of the main pain points in the stack. Like any piece of software, Logstash has a lot of nooks and crannies that need to be mastered to be able to log with confidence. How successful you are at running Logstash is directly determined from how well versed you are at working with this file and how skilled you are at debugging issues that may occur if misconfiguring it. Before we take a look at some debugging tactics, you might want to take a deep breath and understand how a Logstash configuration file is built. This might help you avoid unnecessary and really basic mistakes. Each Logstash configuration file contains three sections — input, filter and output.

Logs are invaluable assets, originating from various sources such as applications, containers, databases, and operating systems. When analyzed, they offer crucial insights, especially in diagnosing issues. For their effectiveness, it's essential to centralize them, allowing for in-depth analysis and pattern recognition all in one place. This centralization process involves using a log shipper , a tool designed to gather logs from diverse sources, process them, and then forward them to different destinations. One powerful log shipper is Logstash , a free and open-source tool created by Elastic and an integral part of the Elastic Stack, formerly known as the ELK stack.
