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)

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
此脚本给与755权限,zabbix用户与组

|
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

#!/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

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。
