  • Application Performance Management in Virtualized Server Environments
    2006 IEEE IFIP Network Operations and Management Symposium NOMS 2006, 2006
    Co-Authors: G. Khanna, G. Kar, Kirk Beaty, Andrzej Kochut
    Abstract:

    As businesses have grown, so has the need to deploy I/T Applications rapidly to support the expanding business processes. Often, this growth was achieved in an unplanned way: each time a new Application was needed a new server along with the Application software was deployed and new storage elements were purchased. In many cases this has led to what is often referred to as "server sprawl", resulting in low server utilization and high system management costs. An architectural approach that is becoming increasingly popular to address this problem is known as server virtualization. In this paper we introduce the concept of server consolidation using virtualization and point out associated issues that arise in the area of Application Performance. We show how some of these problems can be solved by monitoring key Performance metrics and using the data to trigger migration of virtual machines within physical servers. The algorithms we present attempt to minimize the cost of migration and maintain acceptable Application Performance levels

  • Integrated management of Application Performance, power and cooling in data centers
    2010 IEEE Network Operations and Management Symposium - NOMS 2010, 2010
    Co-Authors: Yuan Chen, Chris Hyser, Cullen Bash, Christopher Hoover, Daniel Gmach, Zhikui Wang, Sharad Singhal
    Abstract:

    Data centers contain IT, power and cooling infrastructures, each of which is typically managed independently. In this paper, we propose a holistic approach that couples the management of IT, power and cooling infrastructures to improve the efficiency of data center operations. Our approach considers Application Performance management, dynamic workload migration/consolidation, and power and cooling control to “right-provision” computing, power and cooling resources for a given workload. We have implemented a prototype of this for virtualized environments and conducted experiments in a production data center. Our experimental results demonstrate that the integrated solution is practical and can reduce energy consumption of servers by 35% and cooling by 15%, without degrading Application Performance.

  • Demystifying Application Performance Management Libraries for Android
    2019 34th IEEE ACM International Conference on Automated Software Engineering (ASE), 2019
    Co-Authors: Yutian Tang, Xian Zhan, Xiapu Luo, Yajin Zhou, Zhou Xu, Hao Zhou, Qiben Yan
    Abstract:

    Since the Performance issues of apps can influence users' experience, developers leverage Application Performance management (APM) tools to locate the potential Performance bottleneck of their apps. Unfortunately, most developers do not understand how APMs monitor their apps during the runtime and whether these APMs have any limitations. In this paper, we demystify APMs by inspecting 25 widely-used APMs that target on Android apps. We first report how these APMs implement 8 key functions as well as their limitations. Then, we conduct a large-scale empirical study on 500,000 Android apps from Google Play to explore the usage of APMs. This study has some interesting observations about existing APMs for Android, including 1) some APMs still use deprecated permissions and approaches so that they may not always work properly; 2) some app developers use APMs to collect users' privacy information.
