TasksC++ Advanced Instrumentation
Instrument a complex multi-threaded C++ application simulating a web service with database operations, message queue, and background workers. Requires comprehensive tracing including error handling, async operations, and context propagation across threads.
Common failure modes
- Multi-threaded context propagation - Error handling and exception recording - Multiple service components (DB, MQ, workers) - Requires 15-20 spans with correct relationships - Async span linking - Context lost across thread boundaries - Missing error event recording - Incomplete span relationships
