PerformanceCounterConfiguration.SampleRate Property
Gets or sets the rate at which to sample the performance counter, rounded up to the nearest second.
Namespace: Microsoft.WindowsAzure.Diagnostics
Assembly: Microsoft.WindowsAzure.Diagnostics (in Microsoft.WindowsAzure.Diagnostics.dll)

/** @property */ public TimeSpan get_SampleRate () /** @property */ public void set_SampleRate (TimeSpan value)
public function get SampleRate () : TimeSpan public function set SampleRate (value : TimeSpan)
Property Value
Type: System.TimeSpanReturns TimeSpan.The SampleRate property specifies the frequency for sampling performance counter data. Note that more frequent sampling may incur additional storage costs when the data is transferred to persistent storage at the specified interval.
Performance counters will be transferred to the WADPerformanceCounters table in persistent storage at the specified interval.
Example
The following code snippet creates a new PerformanceCounterConfiguration object, specifies the performance counter and sample rate, adds the configuration to our DiagnosticMonitorConfiguration object, and starts the DiagnosticMonitor.
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 processor time.
diagnosticConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
CounterSpecifier = @"\Processor(_Total)\% Processor Time",
SampleRate = perfSampleRate
});
// Add a performance counter for available memory.
diagnosticConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
CounterSpecifier = @"\Memory\Available Bytes",
SampleRate = perfSampleRate
});
// Schedule a transfer period of 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();
