Performance Monitor是Windows内置的二个可视化监察和控制工具,能够在OS品级上实时记录系统财富的应用景况,通过收集和积攒日志数据,在SQL Server产生非常时,能够东山复起系统及时的能源的施用状态,是对SQL Server进行Troubleshooting的首推工具。Performance Monitor使用Performance Counter来追踪系统的活动状态的衡量值,取样间距私下认可是15s,即,Performance Monitor每间距15s,记录Performance Counter的近来值。

并发以下情形:

系统:windows

Preface

Performance Monitor首要有多个零件:Viewer和Data Collector,分别用于查看和著录Performance Counter的度量值,开启Performance Monitor对Server的熏陶很微小,建议拉开,多搜聚一些属性数据。

重启mysql服务现身 Server] Can't read from messagefile 等不那个时候候,

 

一,查看Viewer

解决办法:

应先实践 mysqld --initialize-insecure 进项初阶化操作

    As we all know,it's a common sense that separate reading and writing operations can immensely increse the performance of MySQL database.Especially the query operations by executing select statement relevant with large tables.Therefore,we usually choose a proxy tool to deal with it.There're a lot of tools can be used nowadays such as mycat(by Apache),dble(based on mycat by Action),atlas,dbproxy(based on atlas of Qihoo360 by MeituanDianping),cetus(by NetEase) and so forth.I'm not going to compare who's the better tool to use.I'm just prefer to having a test on another popular tool which is called "ProxySQL".

1,打开 Performance Monitor

慎选“编辑”——“AMDlisense”——“刷新本地缓存”

接下来重启服务成功

 

点击Windows+Highlander,在Run中输入perfmon,展开Performance Monitor,首要分为多个目录:Monitoring Tools,Data Collector Sets 和 Reports。

或者按Ctrl+Shift+R组合键

    ProxySQL is a low-weight proxy tool based on a SQLite database.It provids hight performance espcially in high concurrent environment what we can see below(compared with the MaxScale).

Performance Monitor是Viewer,有三种查看方式:View Current Activity 和 View Log Data,前面三个用于实时监察当前多少,前者用于查看历史数据。

3,图表(GraphState of Qatar,显示计数器的衡量值

 

能够筛选时间隔绝(zoom to),能够选拔显示和隐身内定的Counter,能够缩放(Scale)Counter的值

*    The configuration of ProxySQL is a three-layer structure:*

4,Sample Interval,实时监督检查能够安装取样间距和呈现的数量长度

 

Performance Monitor的抽样时间间距由属性 Sample Interval 明确,通过Performance Monitor Properties -> General tab查看取样间距设置

  • 勾选Sample automatically:自动取样
  • Sample 伊夫ry  X  seconds:采集样本的时间间隔
  • Duration X seconds:Viewer展现的光阴长短,那是 Real-提姆e 监察和控制形式下保持数据的最长日子
