dns服务目前正常运行，以下开始使用zabbix监控DNS服务.
一、客户端操作
1.登陆dns部署的服务器，安装zabbix客户端，安装客户端 （http://douya.blog.51cto.com/6173221/1431074）
| 1 2 3 | 我的客户端安装路径： /usr/local/zabbix_agent/etc/zabbix_agent .conf 添加以下内容：vim /usr/local/zabbix_agent/etc/zabbix_agent .conf UserParameter=check_dns[*], /usr/local/zabbix_agent/bin/zabbix_monitor_dns .sh $1 然后在 cd /usr/local/zabbix_agent/bin |
添加一个zabbix_monitor_dns.sh文件，内容为

这个脚本的内容就是监控bind管理工具rndc stats产生的一个dns状态信息文件named_stats.txt，这个文件的地址是被/etc/named.conf控制，默认是在
var/named/data目录
| 1 2 | 1、 chmod 755 /usr/local/zabbix_agent/bin/zabbix_monitor_dns .sh 2、 chown zabbix:zabbix /bin/bash /usr/local/zabbix_agent/bin//zabbix_monitor_dns .sh |
然后在crontab里使用root用户添加
1| 1 | * /1 * * * * /bin/bash /usr/local/zabbix_agent/bin/monitor_dns .sh |
/usr/local/zabbix_agent/bin/monitor_dns.sh的内容为
| 1 2 3 4 5 6 7 | #!/bin/bash named_stats= '/var/named/data/named_stats.txt' if [ -e $named_stats ]; then rm -rf $named_stats fi /usr/sbin/rndc stats >> /dev/null 2>&1 mv $named_stats /tmp/ |
这个脚本的作用是每1分钟运行一次rndc status命令，然后把named_stats.txt放到tmp目录下，如果在旧目录里已有这个文件就删除（这样做是因为rndc stats运行后会不断的把信息追加到文件里，而不是覆盖，为了统计方便才删除旧文件，在运行命令生成新文件）
给与脚本755权限
重启zabbix agent服务
| 1 2 | ps -ef| grep zabbix_agentd| grep - v grep | awk -F " " '{print $2}' | xargs kill -9 /usr/local/zabbix_agent/sbin/zabbix_agentd -c /usr/local/zabbix_agent/etc/zabbix_agentd .conf |
二、zabbix服务端操作
1.在zabbix的web界面里连接监控dns模板
在web里选择配置-模板
然后选择导入
然后把之前下载的dns模板。
然后在选择主机加入这个模板即可。
下面是监控的效果图
1、dns的tcp/udp 53端口的监控
2、Incoming Requests
3、Incoming Queries
4、Outgoing Queries
5、Name Server Statistics
6、Resolver Statistics
7、Cache DB RRsets
8、Socket I/O Statistics
目前监控展示方式为增量变化，所以图上显示的值肯定比named_stats.txt里的少。建议还是大家自己根据需要来修改与优化，我这个只是提供一个样例而已，模拟在附件里。
