What is it?

Graylog is a log management platform that gathers log messages from servers, applications and devices so they can be searched and analyzed in one place. It is aimed at operations, security and development teams who need a central view of what their systems are logging.

The project's metadata lists support for GELF, syslog, AMQP and Kafka as ways to get logs in, and tags it for SIEM and security logging use. The server is written in Java and distributed through Maven Central.

The project is published under the Server Side Public License (SSPL), which is a source-available license rather than a standard OSI-approved open source license.
