cacti监控Disk(磁盘)I/O

今天需要监控几个服务器的磁盘IO状态，，在网上查了下资料，，千篇一律，，搞了半天也没搞成功，于是不知道看了多少资料，，终于整合网上的资料，摸索出来了，不容易额，

需要的软件：snmpdiskio-0.9.6.zip

监控机上操作：

1.将下载的snmpdiskio-0.9.6.zip上传到cacit服务器上,解压缩,将partition.xml拷贝resource/snmp_queries下.

unzip snmpdiskio-0.9.6.zip
cp snmpdiskio-0.9.6/partition.xml /var/www/html/cacti/resource/snmp_queries/

2.在cacti服务器的web界面下cacti-->console--->Import/Export--->Import Templates
  "cacti_data_query_snmp_disk_statistics.xml
   cacti_graph_template_disk_io_bytessec.xml"

导入cacti_data_query_snmp_disk_statistics.xml和cacti_graph_template_disk_io_bytessec.xml两个模版

被监控机操作：

3.将下载的snmpdiskio-0.9.6.zip上传到被监控机上,解压缩,将目录下可执行文件snmpdisk拷贝/usr/local/bin/下

unzip snmpdiskio-0.9.6.zip
cp snmpdiskio-0.9.6/snmpdiskio /usr/local/bin

4.修改被监控机的snmpd.conf,在文件的结尾添加如下:

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

重启snmp

Service snmpd restart

5.测试

[root@web-Server bin]# snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.2021.58
UCD-SNMP-MIB::ucdavis.58.1.1 = INTEGER: 1
UCD-SNMP-MIB::ucdavis.58.2.1 = STRING: "hdOutBlocks"
UCD-SNMP-MIB::ucdavis.58.3.1 = STRING: "/bin/sh /usr/local/bin/snmpdiskio hdOutBlocks"
UCD-SNMP-MIB::ucdavis.58.100.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.58.101.1 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.2 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.3 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.4 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.5 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.6 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.7 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.8 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.9 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.10 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.11 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.12 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.13 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.14 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.15 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.16 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.101.17 = STRING: "6394314752"
UCD-SNMP-MIB::ucdavis.58.101.18 = STRING: "6394183680"
UCD-SNMP-MIB::ucdavis.58.101.19 = STRING: "11841024"
UCD-SNMP-MIB::ucdavis.58.101.20 = STRING: "1313280"
UCD-SNMP-MIB::ucdavis.58.101.21 = STRING: "10392576"
UCD-SNMP-MIB::ucdavis.58.101.22 = STRING: "6403810304"
UCD-SNMP-MIB::ucdavis.58.101.23 = STRING: "471040"
UCD-SNMP-MIB::ucdavis.58.101.24 = STRING: "0"
UCD-SNMP-MIB::ucdavis.58.102.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.58.103.1 = ""

出现如上数据,表示正常.

6．在cacti的devicesà Associated Data Queries添加SNMP – Disk Statistics

Create Graphs for this Host选择

选择你要监控的分区即可。

效果图如下：

排错

如果出现

snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.2021.58 UCD-SNMP-MIB::ucdavis.58 = No Such Object available on this agent at this OID

先执行snmpwalk -v 2c -c public localhost,看看是否正常,如不正常,说明snmpd.conf其他配置有问题,如正常,说明刚才添加exec有问题,请检查.

Snmp.conf提前设置
