Transparent System Call Based Performance Debugging for Cloud Computing

Problem diagnosis and debugging in distributed environments such as the cloud and popular distributed systems frameworks has been a hard problem. We explore an evaluation of a novel way of debugging distributed systems, such as the MapReduce framework, by using system calls. Performance problems in such systems can be hard to diagnose and to localize to a specific node or a set of nodes. Additionally, most debugging systems often rely on forms of instrumentation and signatures that sometimes cannot truthfully represent the state of the system (logs or application traces for example). We focus on evaluating the performance debugging of these frameworks using a low level of abstraction - system calls. By focusing on a small set of system calls, we try to extrapolate meaningful information on the control flow and state of the framework, providing accurate and meaningful automated debugging.
