Property Value
Type: System.StringReturns String.The CounterSpecifier property indicates the performance counter you want to monitor. See Specifying a Counter Path for more information on performance counters.
Performance counters will be transferred to the WADPerformanceCounters table in persistent storage at the specified interval.
Example
The following code sample creates new PerformanceCounterConfiguration objects for ASP.NET performance monitoring. For more information on performance counters in ASP.NET, see Performance Counters for ASP.NET
public override bool OnStart()
{
// 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 monitoring queued requests.
diagnosticConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
CounterSpecifier = @"\ASP.NET\Requests Queued",
SampleRate = perfSampleRate
});
// Add a performance counter for request wait time.
diagnosticConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
CounterSpecifier = @"\ASP.NET\Request Wait Time",
SampleRate = perfSampleRate
});
// Add a performance counter for requests per second.
diagnosticConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
CounterSpecifier = @"\ASP.NET\Requests/Sec",
SampleRate = perfSampleRate
});
// Transfer the counters every 30 minutes.
diagnosticConfiguration.PerformanceCounters.ScheduledTransferPeriod = TimeSpan.FromMinutes(30.0);
// Start the DiagnosticMonitor using the diagnosticConfig and our connection string.
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString", diagnosticConfiguration);
return base.OnStart();
