Understanding traceability IDs

A Traceability ID is a String UUID (Universally Unique Identifier) that Guidewire uses to track a single user transaction or operation across multiple logging statements. The logging statements can span calls across multiple applications in inter-application integration. PolicyCenter stores the traceability ID string in a MDC (Mapped Diagnostic Context) object that the Log4j logging system maintains. The MDC object is essentially a key-value map that PolicyCenter stores in a ThreadLocal variable.
