Oracle Cloud Infrastructure - Version N/A and later Linux x86-64 Linux x86 Goal Why CPU usage for processes shows different for ps and top commands. ps command showing 8 processes are above 90% CPU most of the time: [oracle@<HOST> ]$ ps -eo pcpu,pid,user,args | sort -k 1 -r |...
可以看到,显示地项目共分为四项,依次为PID(进程ID)、TTY(终端名称)、TIME(进程执行时 间)、COMMAND(该进程地命令行输入). 可以运用u选项来查看进程所有者及其他少许详细信息,如下所示: $ ps u USER PID %CPU %MEM USZ RSS TTY STAT START TIME COMMAND test 5800 0.0 0.4 1892 1040 ttyp0 S Nov27 0:...
在 Linux 系统下，ps和top命令都会通过/proc/[PID]/stat提供的信息来计算 CPU 占用率[2]：## Name Description14 utime CPU time spent in user code, measured in jiffies15 stime CPU time spent in kernel code, measured in jiffies16 cutime CPU time spent in user code, including...

为了确保方案的可靠实施,我们需要在充分理解free/ps/top等命令有关内存信息准确含义的前提下,分析机器当前的内存情况、以及各worker的内存占用情况,明确nginx和业务程序的worker数分别调低和调高多少,既不会出现内存紧张、又能充分利用机器资源,于是有了本文的几个demo实验。
