Zabbix 的 MySQL 监控客户端配置
Zabbix监控的方式有四个大方向：1，Zabbix Agent类型
2，SNMP类型
3，JMX类型
4，IMPI类型
用的多的基本上就两种，Agent类型 和 SNMP类型。
Agent类型的item是使用部署在服务端的Agent来获取数据，可以分为主动和被动模式。
SNMP是监控服务器以外设备的非常好的方式，比如可以监控网络设备，打印机等，只要是有SNMP功能的，zabbix都可以监控。
今天我们要说的MySQL监控是基于Agent类型的监控。
我们来看看服务端的默认模板：
http://s3.运维网.com/wyfs02/M02/70/B2/wKiom1W7l4eggA3VAADdu9M82Lw486.jpg
item 有14个，根据这14个item生成有2个图形类型。
http://s3.运维网.com/wyfs02/M00/70/AF/wKioL1W7mdOj8bUlAAUhRA47Tmc667.jpg
http://s3.运维网.com/wyfs02/M00/70/B2/wKiom1W7mFGzI6fyAAK2A5cp5aQ632.jpg第一个item的信息如图，监控类型为zabbix agent，key为mysql.version ，输出类型为字符串，更新周期默认为 3600秒。值的保存日期为7天。。。。
被监控端安装好zabbix agent后，添加好MySQL监控模板，然后在Zabbix_server端查看日志的后你会发现
http://s3.运维网.com/wyfs02/M00/70/B2/wKiom1W7mm_RT6vfAAREG17eoX8850.jpg提示监控可以值在被监控端不受支持。
所以我们还需要修改被监控端的 zabbix_agentd.conf 手动添加对应key所执行的数据采集语句（多用SHELL语句编写）。
客户端添加自定义监控项的方法为：在配置文件后面添加语句为 UserParameter=app.key,/some/shell/output
比如：监控mysql.version的话 语句为
mysql.version,mysqladmin -u -p version | grep 'Server version' | awk '{printf "MySQL Server Version: "$3}'
输出的值为 MySQL Server Version: 5.1.73
所以添加到配置文件最后就添加好一条监控项了。
根据上图所示，mysql的值有许多，这些值一般都在 mysqladmin status | mysqladmin extended-status 里面。所以只需要写一个shell脚本就可以吧剩下的全部监控起来。
我这里提供一个shell脚本示例
#!/bin/bash

http://s3.运维网.com/wyfs02/M01/70/B2/wKiom1W7nkfwKm9JAAKPa4XyS_M970.jpg已经陆续获取到响应的值了。
稍等就可以完整监控了。
