记下“p_thread_t”输出中的十六进制值,并在 Thread Dump 中搜索其中哪个线程的“native ID”等于该值。 这将为您揭示造成高 CPU 占用率问题的线程。 下面是 AIX 系统中上述进程的一个示例: 1、ps -mp 250076 -o THREAD 将显示以下内容: USER PID PPID TID ST CP PRI SC WCHAN F TT BND COMMAND user...

Re: Tutorial on sar command You can use man pages of sar in unix to get details.Sar retrieves all of its metrics via the /dev/kmem or pstat(2) interface, although in HP-UX some of the counters are specific only to sar. As with most of the counter-based performance tools, overhe...
SARchart - An opensource version of the tool for viewing Unix SAR data as Charts/Graphs - sargraph/sargraph.github.io GitHubsargraph As I mentioned at the beginning, the power of sar command is incredible, there are plenty more options to use with it, which will allow you to get a lot...
The sar command in Linux is a powerful system activity reporter. It collects, reports, and saves system activity information, providing insights into resource utilization. This allows administrators to monitor performance bottlenecks, troubleshoot issues, and plan for capacity. sar can report on CPU ...
In all the examples below, we are going to explain how to view certain performance data for the current day. To look for a specific day, add “-f /var/log/sa/saXX” at the end of the sar command. All the sar command will have the following as the 1st line in its output. ...
def move(src, dst): """Recursively move a file or directory to another location. This is similar to the Unix "mv" command. If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist. If the dest...
SARstands for System Activity Report, as its name suggest,sar commandis used to collect, report & saveCPU,Memory,I/Ousage in Unix/Linux like operating systems. SAR command generate the reports on the fly and can also save the reports in log files as well. ...
介绍Sar 最早是实现在 Salaris Unix 系统里,后来移植到了大部分其他的 Unix 系统(如AIX,HP-UX等)。Linux 下也有法国人写的 sysstat 实现了这个工具的功能。...它的原理就是使用 cron 定期调度一个程序,收集当前系统各项性能指标,保存在二进制文件里。 --- 安装 可以下载源码,自己编译安装,也可以安装二进制包。
