Abstract
In one embodiment, a method includes allocating a shared memory region accessible by a tracing service and services running in user mode outside of a microkernel of an operating system, in which the shared memory region is used by each service to store entries of execution data from operations executed by the service and each entry of execution data has a task identifier, receiving a query for execution data with a desired task identifier by the tracing service, retrieving a set of entries of execution data from the shared memory region by the tracing service based on the desired task identifier, in which the task identifier of each entry of execution data in the set matches the desired task identifier, and returning the set of entries of execution data by the tracing service.
