zabbix企業應用之bind dns監控（轉）

本文轉載自   查看原文   2015-04-01 10:54   1628    BIND/ dns監控/ Zabbix

繼續介紹zabbix監控企業應用的實例，本次介紹zabbix監控dns，我監控的dns為bind 9.8.2，本dns為公網dns，是為了解決公司內網服務器自動化所需求的dns解析，比如目前的puppet或者salt軟件，如果結合dns，管理起來更方便，對於管理服務器來說，如果搬遷機房或者硬件出現故障，如果有dns解析，那么直接切換域名，30s內生效，這樣故障恢復的時間就會更短，總之有dns做解析的好處多多，這里就不多介紹，如何的安裝可以參考我的文章http://dl528888.blog.51cto.com/blog/2382721/1249311（centos 6.2安裝bind 9.8.2 master、slave與自動修改后更新）

一、客戶端操作

1.登陸dns部署的服務器，安裝zabbix客戶端，然后客戶端的配置文件里，比如我的是/usr/loca/zabbix/conf/zabbix_agentd.conf里添加

UserParameter=check_dns[*],/usr/bin/sudo/usr/local/zabbix/bin/zabbix_monitor_dns.sh $1

然后在cd /usr/local/zabbix/bin/

添加一個zabbix_monitor_dns.sh文件，內容為

這個腳本的內容就是監控bind管理工具rndc stats產生的一個dns狀態信息文件named_stats.txt，這個文件的地址是被/etc/named.conf控制，默認是在/var/named/data目錄

此腳本給與755權限，zabbix用戶與組

1
2
chmod  755  /usr/bin/sudo /usr/local/zabbix/bin/zabbix_monitor_dns.sh
chown zabbix:zabbix /bin/bash /usr/local/zabbix/bin/zabbix_monitor_dns.sh

然后在crontab里使用root用戶添加

1
*/ 1  * * * * /bin/bash /usr/local/zabbix/bin/monitor_dns.sh

/usr/local/zabbix/bin/monitor_dns.sh的內容為

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/

這個腳本的作用是每1分鍾運行一次rndc status命令，然后把named_stats.txt放到tmp目錄下，如果在舊目錄里已有這個文件就刪除（這樣做是因為rndc stats運行后會不斷的把信息追加到文件里，而不是覆蓋，為了統計方便才刪除舊文件，在運行命令生成新文件）

給與腳本755權限

重啟zabbix agent服務

1
2
ps -ef|grep zabbix|grep -v grep|awk  '{print $2}' |xargs kill - 9
/usr/local/zabbix/sbin/zabbix_agentd -c /usr/local/zabbix/conf/zabbix_agentd.conf

二、zabbix服務端操作

1.在zabbix的web界面里連接監控dns模板

在web里選擇配置-模板

然后選擇導入

然后把之前下載的dns模板。

然后在選擇主機加入這個模板即可。

下面是監控的效果圖

1、dns的tcp/udp 53端口的監控

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

目前監控展示方式為增量變化，所以圖上顯示的值肯定比named_stats.txt里的少。建議還是大家自己根據需要來修改與優化，我這個只是提供一個樣例而已，模擬在附件里。
