administration--General---Regular expressions ---New Regular expressions   
	Name: Disk device for discovery   
	Test string: xvdb   
	Expression: ^(sda|sdb|xvda|xvdb)$    
	Expression type: Result is TRUE     
	Case sensitive: Yes   
	配置完成记得选择test---然后保存：  

	iops 创建规则

	01.创建目录   
	1015  mkdir -p /opt/zabbix/linux   
	1016  cd /opt/zabbix/linux/   
	1018  wget https://raw2.github.com/dkanbier/zabbix-linux/master/LLD/queryDisks.pl  --no-check-certificate   
	1019  chmod +x queryDisks.pl   
	1020  chown -R zabbix:zabbix /opt/zabbix/ -R   

	02.修改配置文件添加如下内容：   
	/usr/local/etc/zabbix_agentd.conf   
	UserParameter=custom.vfs.dev.discovery,/opt/zabbix/linux/queryDisks.pl   

	03.zabbix配置应用：   
	配置客户端的key,下载客户端KEY文件  
	wget https://raw2.github.com/dkanbier/zabbix-linux/master/UserParameters/  userparameter_linux_disks.conf --no-check-certificate   
	查看：   
	[root@dota-db-08 zabbix_agentd.conf.d]# cat userparameter_linux_disks.conf   
	#See https://www.kernel.org/doc/Documentation/ABI/testing/procfs-diskstats   
	#	 
	# reads completed successfully   
	UserParameter=custom.vfs.dev.read.ops[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$4}'   
	# sectors read   
	UserParameter=custom.vfs.dev.read.sectors[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$6}'   
	# time spent reading (ms)   
	UserParameter=custom.vfs.dev.read.ms[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$7}'   
	# writes completed   
	UserParameter=custom.vfs.dev.write.ops[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$8}'   
	# sectors written   
	UserParameter=custom.vfs.dev.write.sectors[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$10}'   
	# time spent writing (ms)   
	UserParameter=custom.vfs.dev.write.ms[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$11}'   
	# I/Os currently in progress   
	UserParameter=custom.vfs.dev.io.active[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$12}'   
	# time spent doing I/Os (ms)   
	UserParameter=custom.vfs.dev.io.ms[*],cat /proc/diskstats | egrep $1 | head -1 | awk '{print $$13}'   
	04.重启：   
	[root@dota-db-08 zabbix_agentd.conf.d]# /etc/rc.d/init.d/zabbix_agentd restart   
	Shutting down zabbix_agentd:                              		 [  OK  ]   
	Starting zabbix_agentd:                                         [  OK  ]   
	[root@dota-db-08 zabbix_agentd.conf.d]#   

	如下是客户端可以用脚本来执行：   
	mkdir -p /opt/zabbix/linux && cd /opt/zabbix/linux/ && mkdir /usr/local/etc/zabbix_agentd.conf.d -p && wget https://raw2.github.com/dkanbier/zabbix-linux/master/LLD/queryDisks.pl  --no-check-certificate && chmod +x queryDisks.pl  && chown -R zabbix:zabbix /opt/zabbix/ -R && echo "UserParameter=custom.vfs.dev.discovery,/opt/zabbix/linux/queryDisks.pl" >> /usr/local/etc/zabbix_agentd.conf && cd /usr/local/etc/zabbix_agentd.conf.d && wget https://raw2.github.com/dkanbier/zabbix-linux/master/UserParameters/userparameter_linux_disks.conf --no-check-certificate && killall -9 zabbix_agentd && rm -rf /etc/init.d/zabbix_agentd && chown root:root /usr/local/zabbix/ -R && chmod +x /etc/init.d/zabbix_agentd && chmod +x /usr/bin/who && chown root:root /usr/local/zabbix/ -R && sed -i 's/# Include=\/usr\/local\/etc\/zabbix_agentd.conf.d/ Include=\/usr\/local\/etc\/zabbix_agentd.conf.d/' /usr/local/etc/zabbix_agentd.conf &&   /etc/rc.d/init.d/zabbix_agentd start 

	然后可以查看效果图：
