zabbix 监控服务器的TCP状态

本文介绍如何监控TCP的11种状态:

1、命令选择: ss or netstat

　　netstat 在 Centos7上已经不再支持，ss 打印基于socket的统计信息，实际运行下来，ss的速度比netstat的速度要快很多

 

2、统计脚本,脚本需要设置为定时任务，运行环境是Python2.6 :

  

#!/usr/bin/python
import os,sys
from operator import itemgetter

class tcp_state(dict):

    def __init__(self):
        self.update(self.command())

    def command(self):
        for com in os.popen("/usr/sbin/ss -ant"):
            yield com.split(' ')[0]

    def update(self, iterable=None, **kwds):
        if iterable is not None:
            if hasattr(iterable, 'items'):
                if self:
                    self_get = self.get
                    for elem, count in iterable.iteritems():
                        self[elem] = self_get(elem, 0) + count
                else:
                    dict.update(self, iterable)
            else:
                self_get = self.get
                for elem in iterable:
                    self[elem] = self_get(elem, 0) + 1
        if kwds:
            self.update(kwds)

    def __repr__(self):
       return ','.join(map('%r:%r'.__mod__,self.iteritems()))

def main():
    results = tcp_state()
    for i in results.iteritems():
        command='/usr/bin/zabbix_sender -c 配置文件 -k {0} -o {1}'.format('tcp.{0}'.format(i[0]),i[1])
        os.popen(command)

if __name__ == '__main__':
    main()
