ABSTRACT:
Methods and apparatus, including computer program products, that implement thread-level resource usage measurement. A runtime system to run on top of a native operating system can be operable to perform operations including running threads; taking snapshots of usage of one or more resources in the runtime system, including taking a first snapshot corresponding to a start of execution a thread and a second snapshot corresponding to an end of execution of the thread, where the first snapshot is taken before the second snapshot; and calculating usage of the resources by the thread based on the snapshots. The threads can be running in a virtual machine and snapshots can be measurements of resources at the operating system level.
