python script to monitor cpu usage

In Linux, use python to call the top command to obtain the CPU usage. This article is intended to use python to call the top command to obtain cpu usage, but there is no idea at the moment.To obtain the

This article positioning: The CPU history data has been saved, waiting for visualization analysis, can not be thought of for a moment.This article is a follow-up to the previous article (http://www.jb51.net/article/61956.htm), which mentions how to save the results of the top command in Python under Linux. In Python, we can easily visualize data using matplotlib

Python multithreading vs. multi-process CPU usage# Multi-processThis is not a run-over process before the use of the situationAfter running 2 multi-process:Usage Rate 65%,After running 4 multi-process:CPU Usage: 100%--------------------------------------------------Split Line--------------------------------------------

This article mainly introduces python and bash methods for calculating CPU utilization. It involves Python's reading skills for system hardware information and has some reference value, for more information about how to calculate the CPU usage in python and bash, see the fol

This article describes how to obtain the CPU usage trend chart of a single program using Python. in this article, matplotlib is used to visualize the data. if you need it, refer to the position in this article: you have saved the CPU history data disk, wait for the visualization to perform analysis.

This article describes how to calculate the cpu usage of python, and how to use the win32pdh module in Python. For more information, see the following example. Share it with you for your reference. The specific implementation method is as follows: #-*-Coding = utf-8-*-import win32pdhimport time # Counter pathsPROCESS

Python timer usage + get script where absolute path + define log format test codeIf you write a script with a timer in Python, if the script also read the configuration file, then the configuration file path if you write to die, o

In performance tests, top commands are often used to monitor the CPU and memory usage of a process over a period of time. Output to the file once every 10 seconds. The following code processes the output top file and obtains the CPU utilization. memory has the largest, minimum, and average value. Topfile = raw_input ("please input the topfile path :") Try: Top =

Because the company is using VMware virtualization technology, each time the virtual machine to allocate a connection to the external network IP address, in addition to the company scale, the new people also need to assign IP address, it is easy to cause the IP address of the bad and IP address conflict,So we decided to use a script to troubleshoot the idle usage of IP, reduce the time cost of operations, a
