Solaris系统性能的监控与维护

THE MONITOR AND MAINTENENCE OF SOLARIS SYSTEM PERFORMANCE

目前,由于UNIX操作系统的稳定、高可靠性等诸多优点,ISP服务提供商大多采用UNIX作为提供服务的系统平台,其中Solaris占了其中的很大比例。在Solaris服务器的运行中,经常出现的是系统性能问题。影响系统性能的因素有很多,本文利用Solaris提供的系统工具来对服务器的平均负荷、进程监视、CPU、I/O及内存管理、网络流量诊断等方面进行了分析阐述,给出了在Solaris系统性能维护上的一些命令工具和经验。

At present, because of stability and high reliability of UNIX operating system and so on, ISP service provider uses UNIX as the system platform providing service, in which Solaris take a great proportion. System performance problem often occurs in the Solaris server running, and many factors affect system performance. In this paper, by use of system tools provided in Solaris, server's average load, course surveillance, CPU, I/O and ESM memory, networks flux diagnosis and so on are elucidated, which offers some order tools and experience on the maintenance of Solaris system performance.
