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 $
配置监控脚本:
# cat /etc/zabbix/monitor_scripts/iptables.sh
#!/bin/bash
#iptables 监控脚本
#/-
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
$
查看脚本的权限：
# ll
total
-rwxr-xr-x root root Apr : 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：
# cat Template-iptables.xml
