python监控windows的CPU,Memory,Disk

有一批windows系统需要监控，无论是zabbix、nagios都需要安装相关插件，操作起来比较麻烦。

python的psutil模块可以跨平台监控linux、windows、mac等，于是使用python写监控脚本，然后利用py2exe工具将其打包成exe后，直接将其放到windows下直接运行即可。

1.安装python2.7(32位)

在https://www.python.org/downloads/ 下载适合系统的python

安装后修改环境变量，“系统变量”----PATH最后添加“C:\Python27”

2.安装psutil模块(32位)

在https://pypi.python.org/pypi/psutil 下载适合系统的psutil

在安装前需要先注册python2.7，否则会报错。

编辑注册脚本register.py

import sys
 
from _winreg import *
 
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
 
regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
    installpath, installpath, installpath
)
 
def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"
 
if __name__ == "__main__":
    RegisterPy()

执行完成后，系统会提示“ Python 2.7 is already registered!”

3.编写监控脚本(在此只监控CPU，内存，硬盘的使用率或空闲率，若有其他需要请自己完善)

psutil相关使用文档请参考http://pythonhosted.org/psutil/

#coding=utf8
import psutil
cpu = {'user' : 0, 'system' : 0, 'idle' : 0, 'percent' : 0}
mem = {'total' : 0, 'avaiable' : 0, 'percent' : 0, 'used' : 0, 'free' : 0}

#磁盘名称
disk_id = []
#将每个磁盘的total used free percent 分别存入到相应的list
disk_total = []
disk_used = []
disk_free = []
disk_percent = []

#获取CPU信息
def get_cpu_info():
	cpu_times = psutil.cpu_times()
	cpu['user'] = cpu_times.user
	cpu['system'] = cpu_times.system
	cpu['idle']	= cpu_times.idle
	cpu['percent'] = psutil.cpu_percent(interval=2)
#获取内存信息
def get_mem_info():
	mem_info = psutil.virtual_memory()
	mem['total'] = mem_info.total
	mem['available'] = mem_info.available
	mem['percent'] = mem_info.percent
	mem['used'] = mem_info.used
	mem['free'] = mem_info.free
#获取磁盘
def get_disk_info():
	for id in psutil.disk_partitions():
		if 'cdrom' in id.opts or id.fstype == '':
			continue
		disk_name = id.device.split(':')
		s = disk_name[0]
		disk_id.append(s)
		disk_info = psutil.disk_usage(id.device)
		disk_total.append(disk_info.total)
		disk_used.append(disk_info.used)
		disk_free.append(disk_info.free)
		disk_percent.append(disk_info.percent)
		

if __name__ == '__main__':
	get_cpu_info()
	cpu_status = cpu['percent']
	print u"CPU使用率: %s %%" % cpu_status
	get_mem_info()
	mem_status = mem['percent']
	print u"内存使用率: %s %%" % mem_status
	get_disk_info()
	for i in range(len(disk_id)):
		print u'%s盘空闲率: %s %%' % (disk_id[i],100 - disk_percent[i])
	raw_input("Enter enter key to exit...")  

执行结果如下：

要想监控脚本在其他windows上运行需要安装python环境，但我们可以将监控脚本打包成exe程序发布，只要运行exe程序就能够执行，如何实现呢？

(1)安装打包程序py2exe-0.6.9.win32-py2.7.exe

在http://sourceforge.net/projects/py2exe/files/py2exe/0.6.9/ 下载相应的版本

下载后直接安装即可

(2)编写一个简单的编译脚本setup_py2exe.py

from distutils.core import setup
import py2exe

setup(console=["monitor.py"])

进入dos，在setup_py2exe.py所在的目录运行python setup_py2exe.py py2exe

运行后会在当前目录生成两个文件夹：build和disk，build里面的是一些中间文件可以不用理会，dist里面会产生monitor.exe及其他文件，monitor.exe就是我们需要运行的exe程序，我们需要将dist文件夹发布。

注意：当我们将dist文件夹发布到其他windows机器后，直接运行monitor.exe后，有可能会报错“由于应用程序配置不正确，应用程序未能启动”。这是由于py2exe打包的程序需要9.0.21022.8这个版本的MSVCR90.DLL，我们可以从网上下载并将其放到dist目录下一起发布。另除了9.0.21022.8这个版本的MSVCR90.DLL外，我们还需要Microsoft.VC90.CRT.manifest文件放在dist目录。

Microsoft.VC90.CRT.manifest如下：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
      <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
      <noInheritable></noInheritable>
      <assemblyIdentity type="win32" name="Microsoft.VC90.CRT" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity>
      <file name="msvcr90.dll" />
      </assembly>
