Abstract
Methods and systems are configured for monitoring operations of a computing device by associating threads executing in a user space with kernel events in a kernel space. The systems and methods are configured for detecting a kernel event in the kernel space of the computing device; in response to detecting the kernel event, accessing, from a mapping table that maps a computing thread in the user space to a span that is active on the computing thread, a base address of a memory in the user space of the computing device, the memory storing a span identifier for each span in the user space, the span comprising one or more operations of a computing thread that is active in the user space; accessing, based on the base address, a span identifier in the memory; and associating the span identifier with the kernel event.
