Chapter 1 – Observability Needs of Modern Applications
- You can think about a span as a structured event with a strict but extensible schema, allowing you to track any interesting operation. Spans have trace context that describes the relationships between them. They also have a name, start time, end time, status, and a property bag, with attributes to represent operation details.
Complex and distributed operations need multiple spans that describe at least each incoming and outgoing request. A group of such correlated spans that share the same trace-id is called a trace.
- Spans (also known as Activities in .NET) are created by many libraries and applications. To enable correlation, we need to propagate context within the process ...
