概述

今天主要是導師說要用zabbix監控下TCP連接情況，所以順便整理了這篇文章，下面一起來看看吧！

一、獲取監控數據

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

TCP各監控狀態描述

二、zabbix客戶端配置監控腳本

1、編寫腳本

<code># cat /etc/zabbix/zabbix_agentd.d/tcp_conn_status.sh 
================================================================================================
#!/bin/bash
#this/>#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
================================================================================================/<code>

2、添加自定義參數

<code># cat /etc/zabbix/zabbix_agentd.d/tcp.conf
================================================================================================ 

UserParameter=tcp.status[*],/etc/zabbix/zabbix_agentd.d/tcp_conn_status.sh $1
================================================================================================/<code>

<code>chown -R zabbix:zabbix /etc/zabbix
chmod -R 755 /etc/zabbix/<code>

4、重啟客戶端

<code>systemctl restart zabbix-agent/<code>

5、在zabbix服務端測試

<code>bbix_get -s 172.26.150.134  -p 10050  -k tcp.status[listen]/<code>

三、導入zabbix模板文件

1、下載模板

模板名為：tcp_export_templates.xml，內容如下：

2、導入模板

配置-模板-導入

3、模板/主機鏈接模板

四、查看圖形

監測-圖形

模板領取方式

這份TCP模板怎麼領取呢?

同時希望大家多多轉發分享給更多的朋友哦！
