Graylog is used by engineering and operations teams across a wide range of scenarios. The most common use case is production debugging: when something breaks, engineers need to search across logs from dozens of services simultaneously, not grep through files on individual machines. Graylog makes that search instant.

Beyond debugging, teams use Graylog for infrastructure monitoring — setting up alert conditions that fire when error rates spike, services stop responding, or unusual patterns appear in the logs. Security teams use it for audit and compliance, tracking authentication attempts, access patterns, and anomalies across the entire stack, and retaining logs for the periods required by GDPR, ISO 27001, SOC 2, and HIPAA. Platform teams use it to correlate events across heterogeneous systems — web servers, databases, load balancers, Kubernetes pods — into a single searchable timeline.
