Cacti監控磁盤IO

所需軟體:此軟體網上并不是太好找，建議大家好好收藏

snmpdiskio-0.9.6.zip

下載下傳點http://www.colderboy.com/wp-content/uploads/2011/08/snmpdiskio.rar

1.把解壓之後檔案夾下的snmpdiskio檔案上傳到被監控伺服器的/usr/local/bin目錄下;

由于9.4太老不支援2.6核心,需要修改, 這裡下載下傳的包我已經更新過已經支援2.6核心.

2.把解壓之後檔案夾下的 partition.xml上傳到cacti監控伺服器的

/www/cacti/resource/snmp_queries/目錄下，這裡我的CACTI的

目錄檔案為以上，大家可以根據實際情況修改。

且分别導入2個模闆：

cacti_graph_template_disk_io_bytessec.xml

cacti_data_query_snmp_disk_statistics.xml

3修改snmp配置檔案/etc/snmp/snmpd.conf

#以下五行是我添加的内容

<a>exec .1.3.6.1.4.1.2021.54 hdNum /bin/sh /usr/local/bin/snmpdiskio hdNum</a>

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

4重新開機snmpd服務

/etc/init.d/snmpd restart

五:在cacti監控主機上測試

yum install -y net-snmp-utils*

[root@mail ~]# 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.58.101.11 = STRING: "0"

UCD-SNMP-MIB::ucdavis.58.101.12 = 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: "641941504"

UCD-SNMP-MIB::ucdavis.58.101.18 = STRING: "701440"

UCD-SNMP-MIB::ucdavis.58.101.25 = STRING: "0"

UCD-SNMP-MIB::ucdavis.58.101.26 = STRING: "0"

UCD-SNMP-MIB::ucdavis.58.102.1 = INTEGER: 0

UCD-SNMP-MIB::ucdavis.58.103.1 = ""

看到以上内容說配置成功.

5.CACTI模版配置,這裡有點小難度,需要特别注意

找到Templates--&gt;Host Templates--&gt;找到又上方的Add添加一個主機模版

點開add之後輸入建立的主機模版的名字例如:LINUX-disk-io點選create 進入下一步配置

在Associated Graph Templates選擇Disk-I/O (bytes/sec)點選Add添加

在Associated Data Queries選擇SNMP-Disk Statistics點選 Add 添加

最後點選 Save 儲存完成。

6.為主機建立Graphs

Devices --&gt; 選擇 一個主機 --&gt; Host Template 選擇剛剛建立的linux-disk-io 點選儲存

點選上方的 *Create Graphs for this Host在下面就能看到Data Query [SNMP - Disk Statistics]

這樣清單，清單内顯示你硬碟的資訊。選擇你需要監控的磁盤點選建立完成。
