媲美oracle awr/statspack的mysql awr第一版发布
现发布alpha版mysql awr，其提供的特性类似于oracle awr或statspack+集中式监控。对于原来从事oracle dba或者相关运维的人原来说，这会是个不错的选择。
至于我为什么不选择用zabbix,monyog,nagios等等监控工具，相信各数据库专家们懂的。
系统逻辑结构
支持配置监控多个mysql实例。
关键监控内容
一、源系统配置
建议percona server 5.6/mariadb+，支持mysql,percona,mariadb 5.6,5.7。
启用performance_schema，userstat参数
创建perf_stat用户，授予select information_schema，performance_schema select/truncate权限；
- 确保安装了lsof，或yum install lsof进行安装。
CREATE USER perf_stat@'%' IDENTIFIED BY 'hundsun';
GRANT ALL ON information_schema.* TO perf_stat@'%' ;
GRANT ALL ON performance_schema.* TO perf_stat@'%' ;
二、perfstat配置
1、创建存储表结构
create database perf_stat;
use perf_stat;
Create table apps (hostname varchar(64),port int,appname varchar(64) primary key,ver varchar(64));
Create table app_snaps (hostname varchar(64),appname varchar(64),snap_id int,log_time datetime); 保留7天自动删除
Create index idx_app_snaps_appname on app_snaps(appname);
create table IS_GLOBAL_STATUS(hostname varchar(64),appname varchar(64),log_time datetime,snap_id int,variable_name varchar(64),variable_value varchar(64)); 启动以来全量
Create index idx_global_status_app_snap on IS_GLOBAL_STATUS(appname,snap_id);
create table IS_GLOBAL_VARIABLES(hostname varchar(64),appname varchar(64),log_time datetime,snap_id int,variable_name varchar(64),variable_value varchar(64)); 启动以来全量
Create index idx_global_VARIABLES_app_snap on IS_GLOBAL_VARIABLES(appname,snap_id);
create table ps_events_waits_summary_global_by_event_name

2、配置监控的数据源
在当前版本的mysql awr实现中，暂不支持通过web控制台方式增加监控节点（下一个版本会支持）。
要增加监控的节点，需要在三个地方进行改动，如下所示：
（1）、在WEB-INF/conf/spring-servlet.xml中增加一个类似如下的数据源：
<bean id="hitop_pxc_db1_ds" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="url" value="${hitop_pxc_db1_ds.jdbc.url}" />
<property name="driverClassName" value="${hitop_pxc_db1_ds.jdbc.driverClassName}" />
<property name="username" value="${hitop_pxc_db1_ds.jdbc.username}" />
<property name="password" value="${hitop_pxc_db1_ds.jdbc.password}" />
<property name="maxActive" value="${hitop_pxc_db1_ds.jdbc.maxActive}" />
<property name="maxIdle" value="${hitop_pxc_db1_ds.jdbc.maxIdle}" />
<property name="maxWait" value="${hitop_pxc_db1_ds.jdbc.maxWait}" />
<property name="validationQuery" value="select 1" />
<property name="defaultAutoCommit" value="true" />
</bean>
同时在dataSource中增加对应的条目，如下所示：
<bean id="dataSource" class="com.cyl.kernel.DynamicDataSource">
<property name="targetDataSources">
<map key-type="java.lang.String">
<entry key="localSrc_ds" value-ref="localSrc_ds" />
<entry key="hitop_pxc_db1_ds" value-ref="hitop_pxc_db1_ds" />
<entry key="perfstat_ds" value-ref="perfstat_ds" />
</map>
</property>
<property name="defaultTargetDataSource" ref="perfstat_ds" />
</bean>
（2）、在WEB-INF/conf/jdbc-mysql.properties中增加对应的系统配置，如下所示：
hitop_pxc_db1_ds.jdbc.driverClassName=com.mysql.jdbc.Driver
hitop_pxc_db1_ds.jdbc.url=jdbc:mysql://172.28.1.102:3306/performance_schema?useUnicode=true&characterEncoding=gbk&autoReconnect=true&failOverReadOnly=false
hitop_pxc_db1_ds.jdbc.username=root
hitop_pxc_db1_ds.jdbc.password=hundsun
hitop_pxc_db1_ds.jdbc.maxActive=5
hitop_pxc_db1_ds.jdbc.maxIdle=2
hitop_pxc_db1_ds.jdbc.maxWait=10000
（3）登录使用perf_stat用户登录监控服务器mysql，执行如下insert语句：
USE perf_stat;
INSERT INTO apps(hostname,PORT,appname,ver) VALUES('mysql服务器地址',端口,'唯一标识该mysql实例的id，不得重复','mysql大版本');
如：
INSERT INTO apps(hostname,PORT,appname,ver) VALUES('localhost',3306,'localSrc','5.6');
INSERT INTO apps(hostname,PORT,appname,ver) VALUES('localhost',3306,'localSrc','5.7'); 5.6、5.7经过测试，5.5不确定
三、perfstat后台服务
1、每隔15/20分钟采集一次；采集时会自动过滤mysql、performance_schema、information_schema三个对象中的CRUD以及各种操作
采集时对于PS中表的操作，会设置SET sql_log_bin = off;以避免truncate PS相关表时传播到其他节点（如果主从或者galera cluster的话）
2、自动清除7天前的日志
四、访问
war包下载地址，baidu pan http://pan.baidu.com/s/1slf8h5b。
下一版本计划更新内容：
1、支持界面增加被监控实例，简化配置；
2、支持监控暂停与恢复；
3、支持不同实例不同调度策略；
4、增加slave监控；
