所需软件:此软件网上并不是太好找,建议大家好好收藏
snmpdiskio-0.9.6.zip
下载点http://www.colderboy.com/wp-content/uploads/2011/08/snmpdiskio.rar
 
1.把解压之后文件夹下的snmpdiskio文件上传到被监控服务器的/usr/local/bin目录下;
由于9.4太老不支持2.6内核,需要修改, 这里下载的包我已经更新过已经支持2.6内核.
 
2.把解压之后文件夹下的 partition.xml上传到cacti监控服务器的
/www/cacti/resource/snmp_queries/目录下,这里我的CACTI的
目录文件为以上,大家可以根据实际情况修改。
且分别导入2个模板:
cacti_graph_template_disk_io_bytessec.xml
cacti_data_query_snmp_disk_statistics.xml
 
3修改snmp配置文件/etc/snmp/snmpd.conf

#以下五行是我添加的内容
exec .1.3.6.1.4.1.2021.55 hdIndex /bin/sh /usr/local/bin/snmpdiskio hdIndex
exec .1.3.6.1.4.1.2021.56 hdDescr /bin/sh /usr/local/bin/snmpdiskio hdDescr

exec .1.3.6.1.4.1.2021.58 hdOutBlocks /bin/sh /usr/local/bin/snmpdiskio hdOutBlocks
#----------------------------------------------------------------------------------
 
4重启snmpd服务
/etc/init.d/snmpd restart
 
五:在cacti监控主机上测试
 
yum install -y net-snmp-utils*

看到以上内容说配置成功.
 
5.CACTI模版配置,这里有点小难度,需要特别注意
 
找到Templates-->Host Templates-->找到又上方的Add添加一个主机模版
 
点开add之后输入创建的主机模版的名字例如:LINUX-disk-io点击create 进入下一步配置
 
在Associated Graph Templates选择Disk-I/O (bytes/sec)点击Add添加
 
在Associated Data Queries选择SNMP-Disk Statistics点击 Add 添加
 
最后点击 Save 保存完成。
 
6.为主机创建Graphs
Devices --> 选择 一个主机 --> Host Template 选择刚刚创建的linux-disk-io 点击保存
点击上方的 *Create Graphs for this Host在下面就能看到Data Query [SNMP - Disk Statistics]
这样列表,列表内显示你硬盘的信息。选择你需要监控的磁盘点击创建完成。
