track cpu usage

Python obtains the code for CPU usage, memory usage, and network usage status, and pythoncpu Since psutil has been updated to version 3.0.1, the latest code is as follows: #!/usr/bin/env pythonimport osimport timeimport sysimport atexitimport psutil#print "Welcome,current system is",os.name," 3 seconds late start to ge

Linux is available under the top, PS command to check the current CPU, mem usage. Here's a simple example:First, using PS to view the process of resource consumptionPs-auxWhen you view the process information, the third column is the CPU check-in.[Email protected] utx86]# Ps-aux | grep my_processWarning:bad syntax, perhaps a bogus '-'? See/usr/share/doc/procps-3.

The top command is a common performance analysis tool in Linux. It can display the resource usage of various processes in the system in real time, similar to the Windows Task Manager. The following describes how to use it.

This article mainly introduces 10 methods for detecting Python program running time, CPU usage, and memory usage, including using the Python decorator or external UnixShell commands, for more information about how to run complex Python programs, it may take a long time. in this case, you may want to improve the program execution efficiency. But what should we do?

To solve this problem, most of us will directly reduce the number of mysql accesses and connections and directly generate static or cache files, below I have more ways to solve mysql's high CPU and memory usage.
