Zabbix監控Linux磁盤I/O

東西都上傳到這里了：

https://github.com/RexKang/Zabbix/tree/master/OS/Linux-disk-discovery

 

需要用到的東西：

Zabbix的LLD： https://www.zabbix.com/documentation/2.0/manual/discovery/low_level_discovery

Zabbix的Agent配置： https://www.zabbix.com/documentation/2.0/manual/appendix/config/zabbix_agentd

iostat的使用： http://www.cnblogs.com/peida/archive/2012/12/28/2837345.html

 

1、修改agent配置

我的agent安裝位置是/usr/local/zabbixagent/

vi /usr/local/zabbixagent/conf/zabbix_agentd.conf
Include=/usr/local/zabbixagent/conf/zabbix_agentd
:wq

 

2、建立配置文件

此文件位置在/usr/local/zabbixagent/conf/zabbix_agentd/sysio.conf

# required sysstat
# required iostat running backgroud
##################################################
# nohup iostat -k -x -d 30 > /usr/local/zabbixagent/tmp/iostats &
# chown zabbix:zabbix /usr/local/zabbixagent/tmp/iostats
# cronteb -e
# Zabbix Agent's task for disk I/O
# 59 23 * * * iostat -k -x -d 30 2 > /usr/local/zabbixagent/tmp/iostats &
##################################################
# command for test.

#/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.rkbps[sda]'
#/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.wkbps[sda]'

#/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.await[sda]'
#/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.svctm[sda]'
#/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.util[sda]'

UserParameter=io.scandisk[*],/usr/local/zabbixagent/scripts/discovery-linux.py /proc/diskstats 3

UserParameter=io.util[*],grep -a "$1" /usr/local/zabbixagent/tmp/iostats | tail -1 |awk '{print $$12}'

 

 

3、misc

cd /usr/local/zabbixagent/
mkdir tmp scripts
chmod 775 tmp scripts
touch tmp/iostats
chmod 644 tmp/iostats
touch scripts/discovery-linux.py
chmod 754 scripts/discovery-linux.py
chown zabbix:zabbix ./* -R

 

4、運行

nohup iostat -k -x -d 30 > /usr/local/zabbixagent/tmp/iostats &
sudo service zabbix_agentd restart

 

5、測試

/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.rps[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.wps[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.rkbps[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.wkbps[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.avgrq-sz[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.avgqu-sz[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.await[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.svctm[sda]'
/usr/local/zabbixagent/bin/zabbix_get -s 10.0.0.1 -k 'io.util[sda]'

 

6、添加清理腳本

crontab -e
59 8 * * * iostat -k -x -d 30 2 > /usr/local/zabbixagent/tmp/iostats &

 

7、添加配置

blablabla，這里我就不說了。
