一 监控原理:

[root@ nginx]# /bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}'
TIME_WAIT
FIN_WAIT2
ESTABLISHED
LISTEN
可以使用man netstat查看TCP的各种状态信息描述
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 The socket is closed, and the connection is shutting down
FIN_WAIT2 Connection is closed, and the socket is waiting for a shutdown from the remote end.

二 监控脚本:

tcp_conn_status.sh,放在zabbix-agent的应用服务器上/usr/local/zabbix/bin/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

三 zabbix-agent配置

1、修改tcp_conn_status.sh文件权限:

chmod o+x /usr/local/zabbix/bin/tcp_conn_status.sh

2、在/usr/local/zabbix/etc目录下,创建文件tcp-status-params.conf

vi /usr/local/zabbix/etc/tcp-status-params.conf

3、在tcp-status-params.conf加入以下内容:

UserParameter=tcp.status[*],/usr/local/zabbix/bin/tcp_conn_status.sh $1

4、创建日志文件

# vi /tmp/tcp_status.txt
# chown zabbix:zabbix tcp_status.txt
# chmod tcp_status.txt

5、在/usr/local/zabbix/etc/zabbix_agentd.conf加入以下配置:

UserParameter=tcp.status[*],/usr/local/zabbix/bin/tcp_conn_status.sh $

四 重启zabbix-agent服务

/etc/init.d/zabbix_agentd restart
