Cacti監控磁盤IO

所需軟件:此軟件網上並非太好找，建議你們好好收藏

snmpdiskio-0.9.6.zip

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

 

1.把解壓以後文件夾下的snmpdiskio文件上傳到被監控服務器的/usr/local/bin目錄下;

因爲9.4太老不支持2.6內核,須要修改, 這裏下載的包我已經更新過已經支持2.6內核.

 

2.把解壓以後文件夾下的 partition.xml上傳到cacti監控服務器的

/www/cacti/resource/snmp_queries/目錄下，這裏個人CACTI的

目錄文件爲以上，你們能夠根據實際狀況修改。

且分別導入2個模板：

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

exec .1.3.6.1.4.1.2021.58 hdOutBlocks /bin/sh /usr/local/bin/snmpdiskio hdOutBlocks

#----------------------------------------------------------------------------------

 

4重啓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.58.103.1 = ""

 

看到以上內容說配置成功.

 

5.CACTI模版配置,這裏有點小難度,須要特別注意

 

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

 

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

 

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

 

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

 

最後點擊 Save 保存完成。

 

6.爲主機建立Graphs

Devices --> 選擇 一個主機 --> Host Template 選擇剛剛建立的linux-disk-io 點擊保存

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

這樣列表，列表內顯示你硬盤的信息。選擇你須要監控的磁盤點擊建立完成。
