zabbix 监控tcp_status 状态

监控脚本思路：

用netstat 命令打印出需要得到的值,放到一个txt文件中
用脚本进行分析出所需要的值
传输给zabbix server 端
用模板的形式展现出来

第一步:netstat 打印出文件放入某个文件中

1.1创建一个空文件

touch /tmp/tcp_status.txt
chmod 644 /tmp/tcp_status.txt
chown zabbix.zabbix /tmp/tcp_status.txt

1.2定时把tcp 连接状态写入tcp_status.txt中,文件名称是 vim /etc/zabbix/scripts/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

第二步:用case 方法分析所需要的关键字和值

2.1 在tcp_conns_status.sh脚本中分析tcp_status 都有哪些状态

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

增加执行权限

chmod a+x /etc/zabbix/scripts/tcp_conn_status.sh

第三步:通过zabbix-agent 传输到zabbix-server 端

vim /etc/zabbix/zabbix_agentd.conf中增加

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

第四步:写监控模板
