Assembly: Microsoft.WindowsAzure.Diagnostics (in Microsoft.WindowsAzure.Diagnostics.dll)

Usage

Copy

'Usage
Dim instance As PerformanceCountersBufferConfiguration
Dim value As IList(Of PerformanceCounterConfiguration)

value = instance.DataSources

Syntax

C++

public IList<PerformanceCounterConfiguration> get_DataSources ()

JScript

public function get DataSources () : IList<PerformanceCounterConfiguration>

Property Value

Type: System.Collections.Generic.IList

Returns IList.

Remarks

The DataSources collection stores the list of PerformanceCounterConfiguration objects for each performance counter in a role instance. This property is used when retrieving or adding a PerformanceCounterConfiguration object to PerformanceCounters for your diagnostic monitor configuration, as PerformanceCounters is of type PerformanceCountersBufferConfiguration.

The following code snippet creates a new PerformanceCounterConfiguration object and adds the specified configuration to a DiagnosticMonitorConfiguration object:

Copy

// Get the default initial configuration for DiagnosticMonitor.
DiagnosticMonitorConfiguration diagnosticConfiguration = DiagnosticMonitor.GetDefaultInitialConfiguration();

// Use 30 seconds for the performance counter sample rate.
TimeSpan perfSampleRate = TimeSpan.FromSeconds(30.0);

// Add a performance counter for requests per second.
diagnosticConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
    CounterSpecifier = @"\ASP.NET\Requests/Sec",
    SampleRate = perfSampleRate
});
