Veflog

Veflog is a fictional cross-platform logging framework designed to capture, structure, and transport events from distributed applications. It provides a standard log record format and pluggable transports to integrate with common runtimes, monitoring stacks, and data stores. The aim is to enable consistent, language-agnostic logging across services.

The name combines 've' for versatility with 'flog,' a playful nod to logs. Veflog appears in hypothetical engineering discussions dating from the mid-2010s as an example of an extensible logging system.

Core components include a log-record schema, a minimal core library, and a set of transport adapters. Logs are emitted as JSON Lines, with fields such as timestamp, level, service, host, message, and an attributes map for structured data. A schema registry enforces consistency, while collectors aggregate events from multiple sources. Transports support HTTP(S), message queues, or local files; a query interface provides filtering and simple visualizations. The design emphasizes low latency, low overhead, and language-agnostic APIs.

Common features include structured and contextual logging through scoped contexts, log rotation, sampling, and privacy controls. Veflog is designed to interoperate with existing ecosystems via bridging adapters to OpenTelemetry, Elasticsearch, or cloud logging services. It favors straightforward integration and gradual migration from legacy log formats.

As a hypothetical construct, veflog serves to illustrate principles of distributed logging and interoperability rather than to document a real project.
