cacti添加I/O监控
首先下载snmpdiskio-0.9.6.zip,文件不好找，我已经放在本文章的附件里面。解压snmpdiskio-0.9.6.zip复制partition.xml到cacti/resource/snmp_queries/下面
# cp partition.xml /home/wwwroot/default/cacti/resource/snmp_queries/
分别导入模板文件：
cacti_data_query_snmp_disk_statistics.xml
cacti_graph_template_disk_io_bytessec.xml

http://www.wangjingfeng.com/content/uploadfile/201312/2ce41387348971.png
Cacti has imported the following items:
GPRINT Preset
Normal
Data Input Method
Get SNMP Data (Indexed)
Data Template
Disk - I/O
Graph Template
Disk - I/O (bytes/sec)
在被监控端的/etc/snmp/snmpd.conf结尾添加：
exec .1.3.6.1.4.1.2021.54 hdNum /bin/sh /usr/local/bin/snmpdiskio hdNum
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 .1.3.6.1.4.1.2021.57 hdInBlocks /bin/sh /usr/local/bin/snmpdiskio hdInBlocks
exec .1.3.6.1.4.1.2021.58 hdOutBlocks /bin/sh /usr/local/bin/snmpdiskio hdOutBlocks

安装snmpdiskio到usr/local/bin下面并且给予执行权限
# install -m 0755 -o root -g root -p -v snmpdiskio /usr/local/bin/
`snmpdiskio’ -> `/usr/local/bin/snmpdiskio’
重启snmpd服务
# service snmpd restart
Stopping snmpd:
Starting snmpd:
查看日志
# pwd
/var/log
# cat messages
如果报错：
Dec 18 14:54:39 node7 snmpd: /etc/snmp/snmpd.conf: line 462: Error: ERROR: This output format has been deprecated - Please use the ’extend’ directive instead
Dec 18 14:54:39 node7 snmpd: /etc/snmp/snmpd.conf: line 463: Error: ERROR: This output format has been deprecated - Please use the ’extend’ directive instead

因为snmp V5版本不支持exec所以要把exec改为extend
extend .1.3.6.1.4.1.2021.54 hdNum /bin/sh /usr/local/bin/snmpdiskio hdNum
extend .1.3.6.1.4.1.2021.55 hdIndex /bin/sh /usr/local/bin/snmpdiskio hdIndex
extend .1.3.6.1.4.1.2021.56 hdDescr /bin/sh /usr/local/bin/snmpdiskio hdDescr
extend .1.3.6.1.4.1.2021.57 hdInBlocks /bin/sh /usr/local/bin/snmpdiskio hdInBlocks
extend .1.3.6.1.4.1.2021.58 hdOutBlocks /bin/sh /usr/local/bin/snmpdiskio hdOutBlocks
测试是否出数据：
# snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.2021.58

完全没有问题，下面就可以在cacti上面添加监控：
