Which property can be filtered in *Service Flow* concerning web requests?

The property that can be filtered in Service Flow concerning web requests is the W3C trace id. This trace ID is part of the W3C Trace Context specification, which provides a standardized way to manage and propagate contextual information across distributed systems. By filtering based on the W3C trace ID, users can effectively track and analyze specific requests through various services, gaining insights into performance and dependencies throughout the service flow.

This capability allows teams to pinpoint where issues may arise within a transaction, making it much easier to troubleshoot problems related to specific web requests. The W3C trace ID serves as a unique identifier that ties together all related calls in a distributed application, thus enhancing observability and traceability.

Other properties like instance type, service status, and server load provide valuable insights but do not specifically pertain to the direct tracking and tracing of web requests through their unique identifiers in the same way the W3C trace ID does. Hence, filtering by the W3C trace ID is essential for effective monitoring of web request flows.
