Graylog is used by engineering and operations teams in a wide variety of scenarios. The most common use case is production debugging: when an incident occurs, engineers need to search across logs from dozens of services at once, rather than combing through files on each machine. Graylog makes this search instant.

Beyond debugging, teams use Graylog for infrastructure monitoring — configuring alert conditions that trigger when error rates spike, services go down, or unusual patterns are detected 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.
