在正式的生产环境中，我们常常会需要监控服务器的状态，以保证公司整个业务的正常运转，常常我们会用到像nagios、zabbix这类工具进行实时监控，那么用python我们怎么进行监控呢？这里我们利用了python3调用psutil和yagmail这两个模块进行监测服务器的内存、磁盘、cpu状态（以及我们监控apache运行状态用到的socket模块）

监控内存、磁盘、cpu

import psutil
def mem():
	mem = psutil.virtual_memory()
return mem[2]
def disk():
	disk = psutil.disk_usage('/root')
return disk[3]
def cpu():
	cpu = psutil.cpu_percent(60)
return cpu
a = mem()
b = disk()
c = cpu()
import yagmail
yag = yagmail.SMTP(user = 'xxx@qq.com',
	password = 'cxboscylplifgadd', host =
	'smtp.qq.com')
if a > 80:
	yag.send(to = 'xxx@qq.com', subject =
		'内存报警', contents = '运行内存超过80%请尽快处理',
		cc = 'xxx@qq.com')
yag.close()
if b > 70:
	yag.send(to = 'xxx@qq.com', subject =
		'系统磁盘报警', contents = '系统磁盘超过70%请尽快处理',
		cc = 'xxx@qq.com')
yag.close()
if c > 90:
	yag.send(to = 'xxx@qq.com', subject =
		'cpu报警', contents = 'cpu超过90%请尽快处理',
		cc = 'xxx@qq.com')
yag.close()

监控网页服务(报警)

import socket, yagmail
hosts = ['192.168.8.137:80',
	'192.168.8.15:88'
]
socket.setdefaulttimeout(5)
for host in hosts:
	ip = host.split(':')[0]
port = host.split(':')[1]
server = socket.socket()
res = server.connect_ex((ip, int(port)))# 返回值为0代表ok,
	不为0代表失败
if res == 0:
	pass
else :
	yag = yagmail.SMTP(user = 'xxx@qq.com',
		password = 'cxboscylplifgadd', host =
		'smtp.qq.com')
yag.send(to = 'xxx@qq.com', subject =
	'警告', contents = '%s httpd服务断开请检测' %
	ip, cc = 'xx@163.com')
yag.close()

这样我们的监控脚本python脚本就完成了，现在就只需要拿到服务器执行定时任务就行了。现在我们来检测一下：
