Monalytics: Online Monitoring and Analytics for Managing Large Scale Data Centers
Speaker: Professor Karsten SCHWAN College of Computing Georgia Institute of Technology Title: "Monalytics: Online Monitoring and Analytics for Managing Large Scale Data Centers" Date: Monday, 26 July 2010 Time: 4:00pm - 5:00pm Venue: Lecture Theatre H (near lifts 27 & 28), HKUST Abstract: To effectively manage large-scale data centers and utility clouds, operators must understand current system and application behaviors. This requires continuous monitoring along with online analysis of the data captured by the monitoring system. As a result, there is a need to move to systems in which both tasks can be performed in an integrated fashion, thereby better able to drive online system management. Coining the term 'monalytics' to refer to the combined monitoring and analysis systems used for managing large-scale data center systems, this paper articulates principles for monalytics systems, describes software approaches for implementing them, and provides experimental evaluations justifying principles and implementation approach. Specific technical contributions include consideration of scalability across both 'space' and 'time', the ability to dynamically deploy and adjust monalytics functionality at multiple levels of abstraction in target systems, and the capability to operate across the range of application to hypervisor layers present in large-scale data center or cloud computing systems. Our monalytics implementation targets virtualized systems and cloud infrastructures, via the integration of its functionality into the Xen hypervisor. ********************** Biography: Karsten Schwan is a Regents' Professor in the College of Computing at the Georgia Institute of Technology. He also a Director of the Center for Experimental Research in Computer Systems (CERCS), with co-directors from both GT's College of Computing and School of Electrical and Computer Engineering. The NSF-sponsored CERCS research center's faculty conduct research in experimental computer systems in the domains of Enterprise, High Performance, and Embedded/Pervasive Systems, with members from industry and from federal agencies. Prof. Schwan's M.S. and Ph.D. degrees are from Carnegie-Mellon University in Pittsburgh, Pennsylvania, where he began his research in high performance computing, addressing operating and programming systems support for the Cm* multiprocessor. At the Ohio State University, he established the PArallel, Real-time Systems (PARTS) Laboratory, containing both custom embedded processors and commercial parallel machines, and conducting research on operating and programming system support for cluster computing and for adaptive real-time systems. At Georgia Tech, his work ranges from topics in operating and communication systems, to middleware, to parallel and distributed applications, focusing on information-intensive distributed applications in the enterprise domain (e.g., the operational information systems supporting large enterprises) and in the high performance domain (e.g., high performance I/O, remote data visualization, and online collaboration). Technical topics currently pursued in his research span (1) scalable techniques for virtualizing and managing future multi-core and multi-machine platforms, (2) efficient methods for managing applications and services across multiple machines, including new techniques for runtime performance and behavior monitoring and understanding, (3) middleware for high performance data movement, addressing I/O in future petascale machines and QoS-sensitive data streaming in pervasive and wide area systems, and (4) experimentation with representative applications in the HPC, enterprise, and pervasive domains.
