    摘要： A computer implemented method, apparatus, and computer usable program code for sampling call stack information. Responsive to identifying an interrupt, a determination is made as to whether all processors in a plurality of processors have generated the interrupt. A determination is made as whether to sample the call stack information based on a policy in response to a determination that all of the processors have generated the interrupt. The call stack information is sampled if a determination is made to sample the call stack information based on the policy

    摘要： A computer implemented method, apparatus, and computer usable program code for sampling call stack information. An event is monitored during execution of a plurality of threads executed by a plurality of processors. In response to an occurrence of the event, a thread is identified in the plurality of threads to form an identified thread. A plurality of sampling threads is woken, wherein a sampling thread within the plurality of sampling threads is associated with each processor in the plurality of processors and wherein one sampling thread in the plurality of sampling threads obtains call stack information for the identified thread.

    摘要： A system and method for Java™ call stack sampling combined with native sampling is presented. A kernel-mode device driver records and stores sampled context information that includes a program counter, a thread identifier, and a process identifier. The sampling thread receives a notification from the kernel-mode device driver, and proceeds to collect call stack information from a Java™ Virtual Machine. In turn, the sampling thread retrieves the sampled context information and harvests symbols corresponding to a loaded module. Once symbols are harvested, the sampling thread combines returned call stack nodes with native function leaf nodes into a unified output tree that provides the relationship between the two different node types. In one embodiment, the sampling thread may generate native function leaf nodes and the unified output tree in a post-processing manner.
