Description: A Graylog Stream Rule is a condition that determines how log messages are processed within a stream. These rules are fundamental for the efficient management of data, as they allow filtering, classifying, and directing messages to different workflows based on specific criteria. Each rule consists of a series of conditions that, when met, trigger defined actions such as creating alerts, modifying fields, or routing messages to other streams. Rules can be based on various attributes of the messages, such as severity level, log source, or message content. This provides system administrators and security analysts with the ability to customize how data is handled, thereby optimizing visibility and incident response. The flexibility of stream rules allows organizations to tailor their log monitoring and analysis to their specific needs, enhancing operational efficiency and information security.
