Real time monitoring and tracing of scheduler decisions

摘要

A system, apparatus, and method are directed to enabling a user to analyze real-time scheduling decisions of resources in a computing environment. A scheduler component maps jobs to resources, and schedule jobs for execution. In one embodiment, the scheduler component continually iterates, based on job characteristics, available resources, required resources, policies, or other constraints. While the scheduler component performs its tasks, a scheduling trace interface (STI) component may perform a trace of decisions made by the scheduler component, as well as collect static and/or dynamic state information used by the scheduler component. In one embodiment, the STI component may generate a snapshot of the scheduling decisions, and state information. A user interface may be employed to query the scheduling snapshots to monitor and analyze the scheduling decisions, and state information. In one embodiment, the user may then modify a job, the job's requirements, or the like, based on the analysis.
