1、Solaris5.X系统日常管理CPU占用情况和IO等待情况1、命令：sar-u15（所有CPU均值）结果：11:32:17%usr%sys%wio%idle11:32:180109911:32:191209711:32:200109911:32:211109811:32:2211098Average11098说明：Average为平均值，%idle为CPU空闲百分比，一般小于25%则可判断为CPU占用过高；%wio为IO等待百分比，大于30%就说明IO比较高了2、命令：mpstat（每个CPU占用情况）结果：CPUminfmjfxcalintrithrcswicswmigrsmtxsrwsy
2、sclusrsyswtidl0978450373300238376017165061048042说明：CPU为cpu号，是单cpu就为0，idl为CPU空闲百分比，一般该值小于30左右及说明CPU负荷过高；wt为IO等待数，正常情况都为0，有数代表较繁忙；sys为系统时间使用率；usr为用户时间使用率；查看僵死进程命令：ps-elf-os-oargs结果：SCOMMANDTschedS/sbin/initSpageoutSfsflushS/usr/lib/sysevent/syseventd……说明：Z为僵死进程，如果没有为Z的就说明目前没有将死进程内存占用情况命令：/usr/sbin/prt

6、id00087872841235227104530001980003217063051594说明：free的值为当前物理内存空闲值，与物理内存总数比，如小于20%就说明内存占用过高内存配置命令：/usr/sbin/prtdiag–v结果：Systemclockfrequency:1012MHzMemorysize:131072Megabytes====================================CPUs====================================CPUCPURunL2$CPUCPULSBChipIDMHzMBImpl.Mask----------
