linux:
在linux上手动获得tcp连接数的命令为:netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}'
#ESTABLISHED socket已经建立连接
#CLOSED socket没有被使用,无连接
#CLOSING 服务器端和客户端都同时关闭连接
#CLOSE_WAIT 等待关闭连接
#TIME_WAIT 表示收到了对方的FIN报文,并发送出了ACK报文,等待2MSL后就可回到CLOSED状态
#LAST_ACK 远端关闭,当前socket被动关闭后发送FIN报文,等待对方ACK报文
#LISTEN 监听状态
#SYN_RECV 接收到SYN报文
#SYN_SENT 已经发送SYN报文
在zabbix_agent端编辑配置文件:vi /etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd.d/#编写一个获取tcp状态的脚本:
mkdir /etc/zabbix/zabbix_agentd.d/script
#此处注意,一定不要将脚本直接放到/etc/zabbix/zabbix_agentd.d/目录下,否则zabbix_agent会把它当做自己的配置文件执行,造成重启不成功
vi /etc/zabbix/zabbix_agentd.d/script/tcp_status.sh
#!/bin/bash
#this script is get tcp status
tmp_file=/tmp/tcp_status.txt
/bin/netstat -an|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}' > $tmp_file
case $1 in

output=$(awk '/CLOSED/{print $2}' $tmp_file)

echo -e "\e[033mUsage: sh $0 [closed|closing|closewait|synrecv|synsent|finwait1|finwait2|listen|established|lastack|timewait]\e[0m"
esac#赋予脚本可执行权限
chmod +x /etc/zabbix/zabbix_agentd.d/script/tcp_status.sh
编写zabbix_agent上的自定义key:vi /etc/zabbix/zabbix_agentd.conf
UserParameter=tcp.status[*],/etc/zabbix/zabbix_agentd.d/script/tcp_status.sh $1
重启zabbix_agent:/etc/init.d/zabbix_agent restart
在服务端测试输入参数返回的值:zabbix_get -s 118.190.114.140 -p 10050 -k tcp.status[listen]
最后在zabbix上创建监控项和触发器,附件中上传了一个附件,里面是tcp_status模板,直接在配置——模板——导入即可。
