Graylog

Graylog is a centralized log management platform for ingesting, storing, and analyzing logs and machine data at scale. It helps teams search across multiple data sources, detect operational issues, and support security monitoring workflows.

Key Features

• Centralized collection of logs via common inputs such as Syslog and GELF
• Search, filtering, and field extraction for structured log analysis
• Streams and pipelines to route, transform, and enrich messages
• Dashboards and visualizations for operational and security monitoring
• Alerting and notifications based on queries and event conditions
• Integrations for common log shippers and message brokers (for example Kafka and AMQP)

Use Cases

• Troubleshooting application and infrastructure incidents using centralized search
• Building operational dashboards for service health and error tracking
• Security monitoring and investigations using aggregated log data

Limitations and Considerations

• Typically relies on an external search backend (commonly Elasticsearch or OpenSearch), which adds operational complexity
• License is SSPL, which can be a consideration for some organizations

Graylog is a strong fit for teams that need a mature log analysis workflow with flexible ingestion options and powerful search. It is commonly used to improve observability, incident response, and security-focused log monitoring in a single system.
