Logstash Filters and Pipelines

Welcome to an advanced look at Logstash! So far, you've learned how to get logs into Logstash and apply basic filters. But what happens when your data gets more complex?

In this lesson, we'll explore powerful techniques like conditional logic, managing multiple pipelines, and leveraging advanced filters for intricate data transformations. This will help you handle real-world logging challenges.

Not all logs are created equal! You might have different log formats coming from various services, or you might want to process events differently based on their content.

Conditional logic allows Logstash to apply filters or outputs only when certain conditions are met. This is achieved using if statements, similar to programming languages.

• Use if to check field values, tags, or other event properties.
• Apply specific filters or actions only to matching events.
