Graylog is an open-source log management platform that provides engineering and operations teams with a centralized location to collect, store, search, and analyze log data from their entire infrastructure. Instead of SSH-ing into each server to read log files one by one, you centralize all your logs in Graylog, where they are indexed in real time and can be searched across billions of events in just milliseconds.

The platform is built around three main capabilities. First, it collects log data from virtually any source — servers, applications, containers, network devices, cloud services — using standard protocols such as Syslog, GELF, Beats, raw TCP/UDP, and HTTP. Second, it indexes this data in an embedded OpenSearch engine, making every field instantly searchable. Third, it analyzes the data through a web interface that offers full-text search, customizable dashboards, alert rules, and processing pipelines that can enrich, filter, and route log events in real time.
