Cacti uses snmpdiskio to monitor server Disks

 

Installation environment:

Centos 5.6 x86_64

Cacti-0.8.7g

Snmpdiskio-0.9.4

 

Install

 

1. You can download snmpdiskio in windows. Decompress the downloaded package. After decompression, the README file is an English installation document.

 

A. Upload the snmpdiskio file in the decompressed folder to the/usr/local/bin directory of the monitored server.

Since 9.4 is too old to support 2.6 kernel, need to modify, from http://forums.cacti.net/viewtopic.php? P = 124793 #124793 (the package downloaded on this website has been updated and supports the 2.6 kernel)

B. Upload the partition. xml file in the decompressed folder to the PATH/cacti/resource/snmp_queries/directory of the cacti monitoring server.

 

2. Modify the snmp configuration file/etc/snmp/snmpd. conf.

Exec. 1.3.6.1.4.1.2021.54 hdNum/usr/local/bin/snmpdiskio hdNum

Exec. 1.3.6.1.4.1.2021.55 hdIndex/usr/local/bin/snmpdiskio hdIndex

Exec. 1.3.6.1.4.1.2021.56 hdDescr/usr/local/bin/snmpdiskio hdDescr

Exec. 1.3.6.1.4.1.2021.57 hdInBlocks/usr/local/bin/snmpdiskio hdInBlocks

Exec. 1.3.6.1.4.1.2021.58 hdOutBlocks/usr/local/bin/snmpdiskio hdOutBlocks

 

Add the above content to the configuration file, save and exit.

Restart the snmpd service

Server snmpd restart

 

3. Test on cacti monitoring host
