USERVER_TASK_PROCESSOR_PROFILER_DEBUG

USERVER_TASK_PROCESSOR_PROFILER_DEBUG Dynamic Config

Dynamic config for profiling the coroutine based engine of userver. Dictionary key names are the names of engine::TaskProcessor.

Schema:

# yaml
default:
    main-task-processor:
        enabled: false
        # 2ms
