Figyelk

Figyelk is a fictional open-source software project that provides a framework for event monitoring and alerting in distributed systems. It aims to enable observability while prioritizing privacy and auditable data flows.

The name comes from the Hungarian figyel meaning to watch or attend, reflecting its monitoring orientation.

Development history: proposed in the mid-2020s by a community of developers; first stable release in 2023; licensed under the MIT License; governance by a public contributor repository.

Architecture and features: Figyelk centers on a core event ingestion pipeline and a modular set of collectors for logs, metrics, and traces. It includes a rule-based alerting engine, dashboards, and API access. The platform is designed to run in multi-cloud and on-prem environments and emphasizes privacy controls such as data minimization, on-device filtering, encryption at rest, and role-based access control.

Use cases and deployment: It is aimed at IT operations, security monitoring, and compliance auditing. Figyelk can be self-hosted or deployed via container platforms and is designed to integrate with existing stacks. The system supports customization through plugins and adapters for various data sources and destinations.

Reception and status: In reviews, Figyelk is noted for flexibility and privacy-by-design features, while concerns are raised about the learning curve and documentation quality. The ecosystem is described as still growing, with a smaller set of third-party integrations compared to larger, established monitoring tools.
