eseménynyomvonal

Eseménynyomvonal is a concept used in information technology to describe a sequence of events that records actions, state changes, and interactions within a system. It captures how a process or transaction progresses over time, often with reference to timestamps, sources, and contextual data. The term emphasizes the causal and temporal order of events, making it useful for understanding end-to-end behavior rather than isolated log entries.

A typical eseménynyomvonal includes events with fields such as event type, timestamp, originating component, and identifiers that relate related events (for example a trace ID or correlation ID). In distributed or microservice environments, an eseménynyomvonal helps link actions across services, providing a holistic view of a user request or a system operation. The structure may be part of a broader observability strategy that also involves metrics and traces.

Applications of eseménynyomvonal include debugging and incident response, auditing for compliance, performance analysis, and capacity planning. For example, a user action might generate a chain of events: authentication, authorization check, data retrieval, and response rendering, each logged with its timing and service boundary. In distributed tracing, a trace consists of multiple spans connected by identifiers, representing the end-to-end path of a single operation.

Relation to related concepts: it sits alongside logging, metrics, and tracing, and is closely tied to event-driven architectures and event sourcing. Tools and frameworks for generating and analyzing eseménynyomvonal include logging systems, distributed tracing platforms, and event-streaming technologies.
