SQL Server性能计数器收集汇总方案（Reporting Service）

通过收集计数器信息，并将计数器信息汇总为不同粒度存储，以Reporting Service报表服务器显示。以下是计数器收集汇总的基本架构。

笔者需要收集的SQL Server计数器包括：SQL Server计数器属性详解

一、SQL Server计数器基本架构图

1、 生产服务器通过ODBC开发数据库互联ODBC配置访问监控监控服务器的SQLPerfData，将数据写入该数据库。详情请见计数器部署 SQL Server性能计数器部署（批量）

2、 通过作业调用存储过程spb_Perf_CounterDataCollect将数据从SQLPerfData写入SQLPerfDataStat数据库。

3、 汇总取均值，将15秒钟数据汇总成1分钟，5分钟，半小时，一小时，六小时数据。各个粒度的数据用于不同时段的报表显示。例如1分钟数据汇总可用于显示一天内的报表，一个月的报表则需要一小时的数据才能正常显示。通过作业调用spb_Perf_CounterDataDts汇总。

4、 计算历史数据为基线数据，与当前数据对比。SQL Server基线算法（同比和环比）

二、SQL Server汇总统计架构

如上图所示，计数器架构分别存储三个数据库SQLPerfData、SQLPerfDataStat、SQLPerfDataStat_Histroy；这三个计数器的功能具体如下：

1、 SQLPerfData接收计数器信息

DisplayToID：计数器自动生成，记录计数器启动信息

CounterDetails：计数器自动生成，记录计数器的基本信息

CounterData：记录计数器传入的数据

2、 SQLPerfDataStat统计计数器信息

基本信息模块：

CounterDetails_Collect：用于同步 CounterDetails表数据，用于轮训统计

CounterDetails_Collect_bak：无用计数器备份

CounterDetails_Dts：统计传输控制表，以服务器为单位，记录服务器统计传输时间。

CounterDetails_Report：同步CounterDetails_Collect表信息，通过优化，用于报表显示作用。

数据模块：

CounterData_FifteenSeconds：15秒数据收集，用于同步CounterData表数据。

CounterData_OneMinute：一分钟数据收集，15秒数据均值计算而成；适合查看当天数据。保留7天数据。

CounterData_FiveMinute：五分钟数据收集，一分钟数据均值计算而成；适合查看4天内数据。保留7天数据。

CounterData_HalfHour：30分钟数据收集，一分钟数据均值计算而成；适合查看一周内数据。保留7天数据。

CounterData_OneHour：一小时数据收集，一分钟数据均值计算而成；适合查看一个月内数据。保留永久

CounterData_SixHour：六小时数据收集，一分钟数据均值计算而成；适合查看一年内数据。保留永久

基线模块：

CBaseCounterData_OneMinute：同比基线，可以计算未来一周的数据走势。保留7天数据。

RBaseCounterData_OneMinute：环比基线，可以计算未来一天的数据走势。保留7天数据。

手动维护模块：

CounterTypeDetails：计数器类型和描述信息记录表。

MonitorContorl：手动维护，计数器报警监控控制表。

3、SQLPerfDataStat_Histroy归档计数器信息

CounterData_OneMinute_bak：一分钟数据备份，保留永久。

CounterData_FiveMinute_bak：五分钟数据备份，保留永久。

CounterData_HalfHour_bak：30分钟数据备份，保留永久。

基线模块：

CBaseCounterData_OneMinute_bak：同比基线备份，保留7天。

RBaseCounterData_OneMinute_bak：环比基线备份，保留7天。
