### 监控tcp的11种状态 ###

1、编写shell脚本，传递参数，根据参数返回结果

#!/bin/bash
    
    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、自定义监控tcp的item的key.

[root@wyl01 zabbix_agentd.d]# cat tcp_status.conf 
    UserParameter=tcp.status[*],/usr/bin/sh /etc/zabbix/shell/tcp_status.sh $1

3、创建模板，然后再模板中创建item,traffic和graph，在添加模板前，先用zabbix-get加检测一下是否获取到值了。
