zabbix 监控Linux 主机TCP连接数

环境： Linux 主机 

步骤： 1，在linux 主机上写个脚本执行查询当前tcp 连接的参数输出到相应值得文本中

             2，建立个任务计划，每分钟执行一次

             3， Linux 主机上的 zabbix 客户端配置文件定义好自定义key

             

1, 在/home/zabbix/sh/  建立一个tcpconnection 目录，建立一个net.py 脚本，内容在文章最底下贴出

2，建立任务计划

*/1 * * * *   /usr/bin/python2.6  /home/zabbix/sh/tcpconnection/net.py

3，配置Linux 主机上面的zabbix 客户端配置文件zabbix_agentd.conf

UserParameter=SYN_RECV,/bin/cat /home/zabbix/sh/tcpconnection/SYN_RECV

UserParameter=ESTABLISHED,/bin/cat /home/zabbix/sh/tcpconnection/ESTABLISHED

UserParameter=FIN_WAIT1,/bin/cat /home/zabbix/sh/tcpconnection/FIN_WAIT1

UserParameter=FIN_WAIT2,/bin/cat /home/zabbix/sh/tcpconnection/FIN_WAIT2

UserParameter=TIME_WAIT,/bin/cat /home/zabbix/sh/tcpconnection/TIME_WAIT

4，重启zabbix_agentd 服务

/etc/init.d/zabbix_agentd restart

5，net.py 脚本内容

#!/usr/bin/env python

import os

def main():

    data = get_data()

    SYN_RECV = data.count('SYN_RECV')

    ESTABLISHED = data.count('ESTABLISHED')

    FIN_WAIT1 = data.count('FIN_WAIT1')

    FIN_WAIT2 = data.count('FIN_WAIT2')

    TIME_WAIT = data.count('TIME_WAIT')

    http = data.count('80')

    https = data.count('440')

    write_file('SYN_RECV', SYN_RECV)

    write_file('ESTABLISHED', ESTABLISHED)

    write_file('FIN_WAIT1', FIN_WAIT1)

    write_file('FIN_WAIT2', FIN_WAIT2)

    write_file('TIME_WAIT', TIME_WAIT)

    write_file('http', http)

    write_file('https', https)

    print 'ESTABLISHED', ESTABLISHED

    print 'SYN_RECV', SYN_RECV

    print 'FIN_WAIT1', FIN_WAIT1

    print 'FIN_WAIT2', FIN_WAIT2

    print 'TIME_WAIT', TIME_WAIT

    print 'http', http

    print 'https', https

def get_data():

    a = os.popen('netstat -an')

    data = a.read()

    return data

def write_file(filename, value):

    BASE_DIR = os.path.dirname(os.path.abspath(__file__))

    f=open('%s/%s' %(BASE_DIR, filename),"w")

    f.write(str(value))

    f.close()

if __name__ == '__main__':

    main()
