概述

今天主要是导师说要用zabbix监控下TCP连接情况，所以顺便整理了这篇文章，下面一起来看看吧！

一、获取监控数据

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

TCP各监控状态描述

二、zabbix客户端配置监控脚本

1、编写脚本

# cat /etc/zabbix/zabbix_agentd.d/tcp_conn_status.sh 
================================================================================================
#!/bin/bash
#this script is used to get tcp and udp connetion status
#tcp status
metric=$1
tmp_file=/tmp/tcp_status.txt
/bin/netstat -an|awk '/^tcp/{++S[$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 0
          else
             echo $output
          fi
        ;;
   listen)
          output=$(awk '/LISTEN/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   synrecv)
          output=$(awk '/SYN_RECV/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   synsent)
          output=$(awk '/SYN_SENT/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   established)
          output=$(awk '/ESTABLISHED/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   timewait)
          output=$(awk '/TIME_WAIT/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   closing)
          output=$(awk '/CLOSING/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   closewait)
          output=$(awk '/CLOSE_WAIT/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
        ;;
   lastack)
          output=$(awk '/LAST_ACK/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
         ;;
   finwait1)
          output=$(awk '/FIN_WAIT1/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
         ;;
   finwait2)
          output=$(awk '/FIN_WAIT2/{print $2}' $tmp_file)
          if [ "$output" == "" ];then
             echo 0
          else
             echo $output
          fi
         ;;
         *)
          echo -e "\e[033mUsage: sh  $0 [closed|closing|closewait|synrecv|synsent|finwait1|finwait2|listen|established|lastack|timewait]\e[0m"
esac
================================================================================================

2、添加自定义参数

# cat /etc/zabbix/zabbix_agentd.d/tcp.conf
================================================================================================
UserParameter=tcp.status[*],/etc/zabbix/zabbix_agentd.d/tcp_conn_status.sh $1
================================================================================================

3、授权

chown -R zabbix:zabbix /etc/zabbix
chmod -R 755 /etc/zabbix

4、重启客户端

?systemctl restart zabbix-agent

5、在zabbix服务端测试

bbix_get -s 172.26.150.134  -p 10050  -k tcp.status[listen]

三、导入zabbix模板文件

1、下载模板

模板名为：tcp_export_templates.xml，内容如下：

2、导入模板

配置-模板-导入

3、模板/主机链接模板

四、查看图形

监测-图形
