The text is a detailed guide on using Logstash, a tool designed by Jordan Sissel for collecting, processing, and forwarding log data, with a focus on shipping logs to Coralogix. It explains Logstash's function of aggregating log data through input plugins, processing it with filter plugins, and routing it to various outputs, such as Elasticsearch and local files. The guide also provides several configuration examples, illustrating the use of different plugins like Ruby for event annotation, HTTP for output, JDBC for database input, and file and TCP plugins for various input methods. Each configuration example showcases how to tailor Logstash pipelines using a combination of input, filter, and output plugins, highlighting the flexibility and customization options available for managing log data effectively.
