Logstash configuration files typically have a extension.Logstash configuration files are commonly placed in the directory (the standard location on Linux systems). However, the exact location may vary depending on the installation method and operating system. For instance, if Logstash is deployed using Docker containers, the configuration file location may differ based on container-specific settings.In this configuration file, you will see three key sections: , , and . Each section defines a distinct stage of Logstash processing:The section specifies how Logstash receives data. For example, it can be configured to read from files or receive data via network ports.The section processes data, such as adding or removing fields, or transforming content.The section defines where data is sent, such as to Elasticsearch, files, or other storage systems.For example, the following is a simple Logstash configuration file that reads logs from a file, performs no filtering, and outputs logs to the console:In practical work scenarios, configuring the appropriate , , and sections effectively enables you to handle various data types.
