Using the Windows Azure Diagnostics trace listener Windows Azure Diagnosti UPC-A for .NET cs supports the use of Trace to log messages. The Windows Azure SDK provides the DiagnosticMonitorTraceListener trace listener to capture the messages.

The Windows Azure Diagnostics basic logs data buffer is used to configure their persistence to the Windows Azure Table Service. The trace listener must be added to the Listeners collection for the Windows Azure hosted service. This is typically done through configuration in the appropriate app.

config or web.config file, but it can also be done in code. When it creates a worker or web role, the Windows Azure tooling for Visual Studio adds the DiagnosticMonitorTraceListener to the list of trace listeners specified in the Configuration section of the relevant configuration file.

Methods of the System.Diagnostics.Trace class can be used to write error, warning and informational messages.

When persisting the messages to the storage service, the Diagnostics Agent can filter the messages if a LogLevel filter is configured for the BasicLogsBufferConfiguration. The Compute Emulator in the development environment adds an additional trace listener, so that trace messages can be displayed in the Compute Emulator UI. In this recipe, we will learn how to trace messages using the Windows Azure trace listener.

. How to do it... We are going to see how Visual Studio .NET upc barcodes to use the trace listener provided in the Windows Azure SDK to trace messages and persist them to the storage service. We do this as follows: 1.

Ensure that the DiagnosticMonitorTraceListener has been added to the appropriate configuration file: app.config for a worker role and web.config for a web role.

. 6 . 2. If necessary, add th UPC Code for .NET e following to the Configuration section of app.

config or web.config file:. <system.diagnostics& gt; <trace> <listeners> <add type="Microsoft.WindowsAzure.

Diagnostics. DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.

Diagnostics, Version=1.0.0.

0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics"> <filter type="" /> </add> </listeners> </trace> </system.diagnostics>. 3. Use the following to visual .net UPC-A write an informational message:.

System.Diagnostics.Trac e.

TraceInformation("Information");. 4. Use the following to VS .NET UPC Code write a warning message:.

System.Diagnostics.Trac e.

Warning("Warning ");. 5. Use the following to .net framework GTIN - 12 write an error message:.

System.Diagnostics.Trac e.

TraceError("Error");. 6. Ensure that the Diag .net vs 2010 UPC A nosticMonitorConfiguration.

Logs property is configured with an appropriate ScheduledTransferPeriod and ScheduledTransferLogLevelFilter when DiagnosticMonitor.Start() is invoked..

How it works... In steps 1 and 2, we en UPC-A for .NET sure that the DiagnosticMonitorTraceListener is added to the collection of trace listeners for the web role or worker role. In steps 3 through 5, we see how to write messages to the trace listener.

In step 6, we ensure that the Diagnostic Agent has been configured to persist the messages to the storage service. Note that they can also be persisted through an on-demand transfer. This configuration is described in the Initializing the configuration of Windows Azure Diagnostics recipe in this chapter.

. Digging into Windows Azure Diagnostics There"s more... The Windows Azure SDK v 1.3 introduced full IIS in place of the hosted web core used previously for web roles. With full IIS, the web role entry point and IIS are hosted in separate processes.

Consequently, the trace listener must be configured separately for each process. The configuration using web.config configures the trace listener for IIS, not the web role entry point.

Note that Windows Azure Diagnostics needs to be configured only once in each role, even though the trace listener is configured separately in both the web role entry point and in IIS. The web role entry point runs under a process named WaIISHost.exe.

Consequently, one solution is to create a special configuration file for this process named WaIISHost.exe. config and add the trace listener configuration to it.

A more convenient solution is to add the DiagnosticMonitorTraceListener trace listener programmatically to the list of trace listeners for the web role entry point. The following demonstrates an overridden OnStart() method in a web role entry point modified to add the trace listener and write an informational message:. public override bool On UPC-A for .NET Start() { System.Diagnostics.

Trace.Listeners.Add(new Microsoft.

WindowsAzure. Diagnostics.DiagnosticMonitorTraceListener()); System.

Diagnostics.Trace.AutoFlush = true; System.

Diagnostics.Trace.TraceInformation("Information"); return base.

OnStart(); }. The AutoFlush property is set to true to indicate that messages should be flushed through the trace listener as soon as they are written..
