12、.IntroductionMonitoring the real-time performance data of an application or a system from remote locations, physically away from the deployment site, is immensely helpful to software engineers in supporting their applications. Performance data in the Windows operating system is made accessible to ap
13、plications by means of performance counters. The number of counters (see Appendix F) depends on systems configuration. Examples of performance counters include Available Bytes, % Processor Time, %User Time etc. 4 that are attributes of performance objects such as Memory, Processor or Physical disk,
14、etc. These kinds of performance information would be useful in detecting any performance bottlenecks or more serious problems at the application site.Current tools 1256, which are provided as built-in utilities by many modern operating systems or available as commercial and open source software, can
15、 only monitor a system locally or through a local network. A solution to this problem includes building a web-based tool that would monitor and gather real-time performance data that reflects current state of remote system.In this report we describe our web-based application (see Appendix E) built to monitor performance of a remote server system. This application is a Capstone project 78 for the University of Houston-Clear Lake and is developed for Tietronix Inc. 9. The applic
