The top command monitors CPU utilization, process statistics, and memory utilization. The top section contains information related to overall system status - uptime, load average, process counts, CPU status, and utilization statistics for both memory and swap space. Top command to find out Linux c...
CPU usage is currentlyexpressed as the percentage of time spent running during the entire lifetime ofa process. This is not ideal, and it does not conform to the standards that psotherwise conforms to. CPU usage is unlikely to add up to exactly 100%. %cpu cpu utilization of the process i...
%cpu cpu utilization of the process in"##.#" format. It is the CPU time used divided by the timethe process has been running (cputime/realtime ratio), expressed as apercentage. It will not add up to 100% unless you are lucky. 结论5:ps命令算出来的cpu使用率相对于进程启动时的平均值,...
可以用下面的命令将 cpu 占用率高的线程找出来: ps H -eo user,pid,ppid,tid,time,%cpu,cmd --sort=%cpu 这个命令首先指定参数'H',显示线程相关的信息,格式输出中包含:user,pid,ppid,tid,time,%cpu,cmd,然后再用%cpu字段进行排序。这样就可以找到占用处理器的线程了。

Chapter 8. A Closer Look at Processes and Resource Utilization(第 8 章 流程和资源利用的近距离观察) This chapter takes you deeper into the relationships between processes, the kernel, and system resources. There are three basic kinds of hardware resources: CPU, memory, and I/O. Processes vie...
The top command is used to display real-time information about system processes. It shows a dynamically updated list of processes, their resource utilization, and other details. 19. ps (Process Status): The ps command is used to display information about active processes. Different flags such as...

工欲善其事必先利其器,要想分析清楚linux服务器中的各类问题,比如性能问题,服务程序的bug,那么必须对该系统下的分析工具有一定的了解,本文对当前的主流cpu,内存,网络,io以及各种debug分析工具(blktrace,perf,systemtap)做了个简单总结。 注:学无止境,故需持续更新 ...
