Wiring Distributed Tracing from Microservices to Mainframe COBOL Batch Jobs
Distributed tracing across the microservices-to-mainframe boundary requires bridging two fundamentally different execution models: synchronous HTTP request-response cycles and asynchronous batch job processing with no inherent caller-callee relationship. This article maps an executable path using OpenTelemetry as the unifying telemetry layer, with version-anchored configuration for each integration point. The Core Problem: Two Worlds, One Trace ID…
