一、获取监控数据

# /bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}'

LISTEN

ESTABLISHED

TIME_WAIT

TCP各监控状态描述

ESTABLISHED       socket已经建立连接

CLOSED            socket没有被使用，无连接

CLOSING           服务器端和客户端都同时关闭连接

CLOSE_WAIT        等待关闭连接

TIME_WAIT         表示收到了对方的FIN报文，并发送出了ACK报文，等待2MSL后就可回到CLOSED状态

LAST_ACK          远端关闭，当前socket被动关闭后发送FIN报文，等待对方ACK报文

LISTEN            监听状态

SYN_RECV          接收到SYN报文

SYN_SENT          已经发送SYN报文

FIN_WAIT1         客户端调用close()关闭连接后，TCP发出FIN标记主动关闭连接，然后进入FIN_WAIT1状态，等待远程TCP连接中断或者确认

FIN_WAIT2         半关闭状态，主动关闭端(也就是客户端调用close()后)接收到ack确认后，此时进入FIN_WAIT2状态，该状态下，客户端应用程序依然能接收数据

二、监控脚本

# cat /etc/zabbix/tcp_conn_status.sh

#!/bin/bash

#this script is used to get tcp and udp connetion status

#tcp status

metric=$

tmp_file=/tmp/tcp_status.txt

/bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}' > $tmp_file

case $metric in

   closed)

          output=$(awk '/CLOSED/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   listen)

          output=$(awk '/LISTEN/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   synrecv)

          output=$(awk '/SYN_RECV/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   synsent)

          output=$(awk '/SYN_SENT/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   established)

          output=$(awk '/ESTABLISHED/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   timewait)

          output=$(awk '/TIME_WAIT/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   closing)

          output=$(awk '/CLOSING/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   closewait)

          output=$(awk '/CLOSE_WAIT/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

        ;;

   lastack)

          output=$(awk '/LAST_ACK/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

         ;;

   finwait1)

          output=$(awk '/FIN_WAIT1/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

         ;;

   finwait2)

          output=$(awk '/FIN_WAIT2/{print $2}' $tmp_file)

          if [ "$output" == "" ];then

             echo

          else

             echo $output

          fi

         ;;

         *)

          echo -e "\e[033mUsage: sh  $0 [closed|closing|closewait|synrecv|synsent|finwait1|finwait2|listen|established|lastack|timewait]\e[0m"

esac

三、修改zabbix_agentd.conf配置文件，并重启zabbix-agent服务

# cat /etc/zabbix/zabbix_agentd.conf

PidFile=/var/run/zabbix/zabbix_agentd.pid

LogFile=/var/log/zabbix/zabbix_agentd.log

LogFileSize=

Server=192.168.x.x

Hostname=192.168.x.x

Include=/etc/zabbix/zabbix_agentd.d/*.conf

UnsafeUserParameters=1

UserParameter=tcp.status[*],/etc/zabbix/tcp_conn_status.sh $1

# systemctl restart zabbix-agent

# 修改生成文件tc-_status.txt文件的权限
# chmod 777 /tmp/tcp_status.txt

四、在zabbix-master端进行测试，看看能否获取到数据

 [root@zabbix-master ~]# zabbix_get -s 192.168.5.150 -p   -k tcp.status[listen]

五、导入zabbix模板文件

文件名：tcp_export_templates.xml，内容如下

<?xml version="1.0" encoding="UTF-8"?>

    <version>2.0</version>

    <date>--16T10::55Z</date>
