CPU Utilization是衡量程序占用系统资源的最直观指标,即CPU使用率。如果CPU Utilization在5%-10%之间则基本上对系统没有影响,可以不关注。但如果在80%-90%,或者更高的话,就可能出现处理器性能瓶颈了。 User Time - 用户时间 描述CPU耗费在用户进程上的百分比,包括Nice time。如果User Time值很高,则表明系统正在执行...

There are a couple of other ways to check the CPU and memory utilization on Linux, but the ones highlighted above are among the most reliable and easiest ways. The regular top command that's installed by default is the most popular way to check CPU and memory utilization onLinux machines. ...
Top command to find out Linux cpu usage Type the top command: $ top Output: You can see Linux CPU utilization under CPU stats. The task’s share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time. In a true SMP environment (multiple CPUS...
ps Command: The ps command provides information on the system's current processes, including their CPU utilization. To use it to see the CPU utilization of all processes, type ps aux in the terminal and hit enter.This is it! Use the above commands to check your system's CPU usage and ...

The iostat command monitors and displays CPU utilization and disk I/O metrics. This includes CPU load, IOPS, read/write throughput, and more.For example:iostat -d -p sda 5Some iostat options:-c –Display CPU utilization info -t –Print timestamp for each report -x –Show extended stats ...
4.CPU Utilization -- CPU利用率 CPU utilization is a straightforwardconcept. At any given time, the CPU can be doing one of seven things. First, itcan be idle, which means that the processor is not actually doing any work andis waiting for something to do. Second, the CPU can be runni...
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 ...
