zabbix自带的"Template OS Linux"模板支持监控已经挂载的磁盘空间利用率，是利用LLD(Low-level discovery )实现的，却没有对磁盘IO监控。
思 路:首先创建Discovery rules，在agent端配置对应的UserParameter,调用shell脚本，动态查找出已经挂载的磁盘分区；然后创建Item prototypes，使用vfs.dev.read[device,<type>,<mode>]和 vfs.dev.write[device,<type>,<mode>]来监控磁盘分区的IO,包括磁盘读写速率、每秒读写扇 区数、每秒写操作数；然后创Graph prototypes,生成磁盘IO图表。（zabbix服务器端通过与zabbix agent通信来获取客户端服务器的数据；agent分为两个版本，其中一个是主动一个是被动，在配置主机我们可以看到一个agent，另一个是 agent(active)。前者为被动检测，后者为主动检 测；关建点来了vfs.dev.read[device,<type>,<mode>]就是监控项keys）
zabbix agent类型所有key:http://ju.outofmemory.cn/entry/76305
首先做io动态监控的zabbix_agent端执行该脚本:
#!/bin/sh
#
# Filename: autoMonitorDiskIO.sh
# Date: 2017-02-15
# Description: 部署zabbix low-level discovery 监控磁盘IO
# Notes: 在被监控客户端运行此脚本,前提条件已经安装好zabbix agent
# ROOT_UID=0
if [ "$UID" -ne "$ROOT_UID" ];then
echo "Error: Please run this script as root user."
exit 1
fi # 自行修改为你的zabbix agent配置文件路径
AGENT_CONF="/etc/zabbix/zabbix_agentd.conf" mkdir -p /etc/zabbix/monitor_scripts
# 创建 low-level discovery mounted disk 脚本
cat > /etc/zabbix/monitor_scripts/mount_disk_discovery.sh << 'EOF'
#!/bin/bash

printf '}\n'
} case "$1" in

echo "Bad Parameter."
echo "Usage: $0 mount_disk_discovery"
exit 1
;;
esac

然后在zabbix_server的web端，导入下面的模板：
模板的名子为: TemplateLinuxDiskIO.xml
内容如下:<version>2.0</version>这里的版本号不能与zabbix_server的版本号差的太多，不然会失败！！！！！

如图：
Configuration------>Templates--------->import
Configuration----->Templates 来查看导入的模板:
查看添加的Template:
现在就可以了，接下来要做的就是：把这个Template加入zabbix_agent的步骤如下:
Configuration--->Host---->test2:如图:
点击Templates,选择模板 下图所示:
查看test2的items:
下面看看一下效果：
在部署后，不会马上看到效果，而是这种效果 Template Linux DiskIO: Disk IO 的Items (0) 等 一段时间 就会好的！！
