[iyunv@monitor scripts]# vim /usr/local/scripts/tcp_connections.sh
#!/bin/bash

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

case $1 in

[iyunv@monitor scripts]# vim /usr/local/scripts/tcp_connections.sh

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

测试脚本是否可用

[iyunv@monitor scripts]# chmod +x tcp_connections.sh
[iyunv@monitor scripts]# ./tcp_connections.sh ESTABLISHED
125

[iyunv@monitor scripts]# chmod +x tcp_connections.sh
[iyunv@monitor scripts]# ./tcp_connections.sh ESTABLISHED
125

编辑zabbix_agentd配置

[iyunv@monitor scripts]# vim /usr/local/etc/zabbix_agentd.conf.d/monitor_tcp_connections.conf
UserParameter=tcp.time_wait,/usr/local/scripts/tcp_connections.sh TIME_WAIT
UserParameter=tcp.close_wait,/usr/local/scripts/tcp_connections.sh CLOSE_WAIT
UserParameter=tcp.fin_wait1,/usr/local/scripts/tcp_connections.sh FIN_WAIT1
UserParameter=tcp.established,/usr/local/scripts/tcp_connections.sh ESTABLISHED
UserParameter=tcp.syn_recv,/usr/local/scripts/tcp_connections.sh SYN_RECV
UserParameter=tcp.last_ack,/usr/local/scripts/tcp_connections.sh LAST_ACK
UserParameter=tcp.listen,/usr/local/scripts/tcp_connections.sh LISTEN

[iyunv@monitor scripts]# vim /usr/local/etc/zabbix_agentd.conf.d/monitor_tcp_connections.conf
UserParameter=tcp.time_wait,/usr/local/scripts/tcp_connections.sh TIME_WAIT
UserParameter=tcp.close_wait,/usr/local/scripts/tcp_connections.sh CLOSE_WAIT
UserParameter=tcp.fin_wait1,/usr/local/scripts/tcp_connections.sh FIN_WAIT1
UserParameter=tcp.established,/usr/local/scripts/tcp_connections.sh ESTABLISHED
UserParameter=tcp.syn_recv,/usr/local/scripts/tcp_connections.sh SYN_RECV
UserParameter=tcp.last_ack,/usr/local/scripts/tcp_connections.sh LAST_ACK
UserParameter=tcp.listen,/usr/local/scripts/tcp_connections.sh LISTEN

重启服务

[iyunv@monitor scripts]# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd:                               [确定]
Starting zabbix_agentd:                                    [确定]

[iyunv@monitor scripts]# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd:                               [确定]
Starting zabbix_agentd:                                    [确定]

测试监控是否有数据

[iyunv@monitor scripts]# zabbix_get -s localhost -k tcp.established
126

[iyunv@monitor scripts]# zabbix_get -s localhost -k tcp.established
126

然后在web里创建模版，方便以后多台添加

填写模版名称

创建监控项

创建图形

模版创建完成后，要关联到监控主机
点击主机，选择模版

等一会儿数据图形就会出现
