zabbix 实现 iptables 监控
安装iptstate
# yum install iptstate
配置zabbix key
iptables.conf
# cat /etc/zabbix/zabbix_agentd.d/iptables.conf UserParameter=iptstate[*],/etc/zabbix/monitor_scripts/iptables.sh $1
配置监控脚本:
# cat /etc/zabbix/monitor_scripts/iptables.sh #!/bin/bash #iptables 监控脚本 #2016/11-18 function tcp { sudo iptstate --single | grep tcp | wc -l } function tcp-syn { sudo iptstate --single | grep SYN | wc -l } function tcp-timewait { sudo iptstate --single | grep TIME_WAIT | wc -l } function tcp-established { sudo iptstate --single | grep ESTABLISHED | wc -l } function tcp-close { sudo iptstate --single | grep CLOSE | wc -l } function udp { sudo iptstate --single | grep udp | wc -l } function icmp { sudo iptstate --single | grep icmp | wc -l } function all { sudo iptstate --single | wc -l } # Run the requested function $1
查看脚本的权限：
# ll total 8 -rwxr-xr-x 1 root root 622 Apr 24 18:44 iptables.sh
添加sudo执行权限：
sed -i "s/^Defaults requiretty/#Defaults requiretty/g" /etc/sudoers echo “zabbix ALL=NOPASSWD: /usr/sbin/iptstate” /etc/sudoers
模板配置：

导入模板:
重启zabbix-agent:
# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent: [ OK ]
Starting Zabbix agent: [ OK ]
增加模板本上档host
