Graylog is a comprehensive open-source log management platform that combines powerful search capabilities, real-time analysis, and SIEM functionality. It uses Elasticsearch/OpenSearch as its storage backend with MongoDB for metadata, providing end-to-end log management with collection, storage, search, and visualization. Key features include streams & pipelines for real-time log categorization, sophisticated processing rules, configurable alerting system, and content packs for common log sources. Graylog offers both open-source and commercial editions, with enterprise features available for larger deployments. The platform is particularly valued for its balance between simplicity and power, offering more integration than bare Elasticsearch while being more focused on logs than general-purpose platforms. Released under Server Side Public License (SSPL) v1.
