SQLdiag-配置文件-PerfmonCollector

前一篇我们已经使用默认配置文件收集了部分诊断数据，并且知道配置文件会影响收集数据的内容。这一篇我们重点讲述配置文件中与性能计数器相关的操作。
可使用XML模板控制SQLdiag使用的收集器。每个收集器可以使用配置文件的<enabled="true">或<enabled="false">来启用或禁用。使用自己最喜欢的文件编辑器，甚至在支持XML文档编辑的Management Studio中修改XML配置文件。不要从XML文件中删除收集器，因为如果XML文件不能匹配，随后SQLdiag将不能加载XSD。
首先让我们使用SD_Detailed.XML配置文件收集5分钟数据：

cd D:Program FilesMicrosoft SQL Server100ToolsBinn
SQLdiag /I F:TroubleShootingSQLdiaginputSD_Detailed.XML /O F:TroubleShootingSQLdiagLocalOutput  /E +00:05:00

生成的文件如下：

SQLDIAG：收集PerfMon数据，对应PerfmonCollector元素
WORK_SQLDIAG_SQL08R2_sp_trace：收集的跟踪数据，对应ProfilerCollector元素
其他文件的说明见上一篇，在我本地收集5分钟性能监视器文件达到19Mb、跟踪数据文件为7Mb(没有做任何其他操作)。

性能计数器数据，与收集计数器数量、轮询时间间隔有关。与收集时长是线性增长关系。
跟踪数据，与添加的跟踪事件，系统繁忙程度有关。收集的大小可能不成比例地膨胀。
建议在高峰时段短暂地运行SQLdiag约10-15分钟，来估计Profiler跟踪事件的生成率和耗费的磁盘空间。这使你能够在数据被改写之前，对将要捕获的活动的时间跨度形成一个粗略的近似。PerfMon文件并不像Profiler跟踪文件一样迅速地增大。Profiler跟踪收集到目前为止是SQLdiag中最消耗资源的数据收集组件。
PerfmonCollector
虽说收集PerfMon数据的开销相比其他数据收集器是最低的，但也不必要将所有性能计数据器都启用。本节将按照下面步骤测试：
1>禁用EventlogCollector、BlockingCollector、ProfilerCollector、CustomDiagnostics元素收集器；PerfmonCollector、SqldiagCollector元素保持启用
2>参照之前配置的数据收集器模板PerfmonLine启用/禁用PerfmonCollector元素下对应的计数器

注意对象下有多实例的情况，比如<PerfmonObject name="Processor(*)" enabled="true">
它会收集Processor对象下指定计数器中所有实例的信息(包含_Total)；在对象上的enabled="false"并不能禁用其下计数器的收集，必须显示在PerfmonCollector元素层或者底层计数器设置enabled="false"
很难一次将所有计数器调整成PerfmonLine模板所配置的，只有修改后让其收集性能计数器，然后查看收集的数据，如此反复几次。修改后收集的数据如下，图形中可能不会呈现出所有收集的计数器，我们可以右击将其他可用的计数器添加到面板。

测试禁用对象<PerfmonObject name="LogicalDisk(*)" enabled="false">，但其下的部分计数器是开启的

我们查看收集到的数据中还是有对应计数器，难道启用/禁用只有在顶层元素设置才会对其下的对象有影响？

结合SQL Nexus完善PerfmonCollector的收集
我们使用sqlnexus导入收集的SQLdiag数据，我们主要查看Perfmon Summary，点击Perfmon Summary出现的页面几乎没数据！

是否还记得我们在RML中有使用Proflier，查看RML所调用的过程/语句。此处我们也利用Proflier监控sqlnexus所调用的过程/语句(跟踪添加筛选器ApplicationName类似于sqlnexus)
我们重新点击Perfmon Summary，在Proflier跟踪下看到如下信息：

查看详细代码可知IO、CPU、Memory是来自下面计数器

<Counter>Process(*)IO Data Bytes/sec</Counter>
<Counter>Process(*)\% Processor Time</Counter>
<Counter>Process(*)Private Bytes</Counter>

而这些计数器刚好没有收集(仅仅收集Process(sqlservr)一个实例)
点击 Click here to view more IO metrics..没有数据：

查看Proflier跟踪下看到如下信息：

查看详细代码可知IO详细信息是来自下面计数器

<Counter>LogicalDisk(*)Avg. Disk sec/Read</Counter>
<Counter>LogicalDisk(*)Avg. Disk sec/Write</Counter>
<Counter>LogicalDisk(*)Disk Bytes/sec</Counter>
<Counter>LogicalDisk(*)Avg. Disk Queue Length</Counter>

点击Click here to view more CPU/Memory metrics..报错

查看Proflier跟踪下看到如下信息：

单独取语句到查询窗口执行，报错“从字符串转换日期和/或时间时，转换失败。”但将CounterDateTime截取再转就可以

点击 Click here to view more Network metrics..没有数据：

查看Proflier跟踪下看到如下信息：

查看详细代码可知NetWork详细信息是来自下面计数器

<Counter>Network Interface(*)Output Queue Length</Counter>
<Counter>Network Interface(*)Packets Received Discarded</Counter>
<Counter>Network Interface(*)Packets Outbound Discarded</Counter>
<Counter>Network Interface(*)Bytes Total/Sec</Counter>

针对上面的问题，解决方案如下：
1>将上面列出的Process(*)、LogicalDisk(*)、Network Interface(*)相关计数器启用
2>使用如下语句更新CounterData中的CounterDateTime字段

USE sqlnexus
GO
UPDATE CounterData SET 
CounterDateTime=LEFT(CounterDateTime,22)

导入数据时有跟踪到创建counterdata的脚本，但没找到原始建表语句保存在哪。另外在sqlnexus应用程序目录的PerfStatsAnalysis.sql文件中有对CounterData表的alter/update语句...
以上问题修正后，再次收集数据用sqlnexus工具查看

我们可以针对每个图形跟踪其涉及的数据，并最终定位来自哪些计数器。如果已经启用相应的计数器，但是在图形中没有看到，就要查看展现的语句是如何处理的，sqlnexus会对部分数值进行单位换算(类似RML中的Scale)。当前SD_Detailed.XML配置文件的PerfmonCollector元素部分可参考文件链接对应部分。
