caching - Windows Azure - 角色内缓存、监控

Question

我正在尝试启动并运行角色内缓存。

我很难确定缓存是否正在使用(因为我们有一个包装器，如果缓存不可用，它会优雅地返回 null，但很难解决)。

我一直在阅读这些文章: Monitor In-Role Cache In-Role Cache For Windows Azure

我想使用管理控制台检查缓存的读/写或其他指标，作为确定缓存是否正常工作的一种方法。但我没有看到任何地方可以查看这些数据。

角色的添加指标窗口不包含任何缓存数据(尽管我可以看到缓存是在“配置”屏幕上配置的)。

有什么建议吗？我要疯了。

1. 将diagnostics.wadcfg 添加到您的角色，其中包含您感兴趣的缓存性能计数器，即

   <?xml version="1.0" encoding="utf-8"?>
   <DiagnosticMonitorConfiguration configurationChangePollInterval="PT1M" overallQuotaInMB="4096" xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration">
     <DiagnosticInfrastructureLogs />
     <Directories>
       <CrashDumps container="wad-crash-dumps" />
     </Directories>
     <Logs bufferQuotaInMB="1024" scheduledTransferPeriod="PT1M" scheduledTransferLogLevelFilter="Error" />
     <WindowsEventLog bufferQuotaInMB="1024" scheduledTransferPeriod="PT1M" scheduledTransferLogLevelFilter="Error">
       <DataSource name="Application!*" />
     </WindowsEventLog>
     <PerformanceCounters bufferQuotaInMB="512" scheduledTransferPeriod="PT5M">
       <PerformanceCounterConfiguration counterSpecifier="\Memory\Available MBytes" sampleRate="PT3M" />
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Available Cache Item Percentage" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Cache Miss Percentage" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Throttled Connections Count" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Allocated Cache Item Count" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Cache Misses /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Client Requests /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Connections Count" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Failure Exceptions /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Get Misses /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Get Requests /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total GetAndLock Requests /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Notification Delivered /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Object Count" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Objects Returned /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Read Requests /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Requests Served /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Retry Exception /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Successful GetAndLock Requests /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Total Write Operations /sec" sampleRate="PT3M"/>
       <PerformanceCounterConfiguration counterSpecifier="\Windows Azure Caching:Host\Available Cache Item Percentage" sampleRate="PT3M"/>
     </PerformanceCounters>
   </DiagnosticMonitorConfiguration>
   

2. 重新部署

3. 在 Azure 管理门户中启用详细监控级别(选项卡配置)
4. 等待一个小时左右
5. 现在您的缓存性能计数器应该可以在标签监视器下添加(添加指标对话框)
