Examples

The following code example demonstrates how to create a PerformanceCounterInstaller object and add it to an InstallerCollection.

#using <System.dll>
#using <System.Configuration.Install.dll>

using namespace System;
using namespace System::Configuration::Install;
using namespace System::Diagnostics;
using namespace System::ComponentModel;

[RunInstaller(true)]
ref class MyPerformanceCounterInstaller: public Installer
{
public:
   MyPerformanceCounterInstaller()
   {
      try
      {
         // Create an instance of 'PerformanceCounterInstaller'.
         PerformanceCounterInstaller^ myPerformanceCounterInstaller =
            gcnew PerformanceCounterInstaller;
         // Set the 'CategoryName' for performance counter.
         myPerformanceCounterInstaller->CategoryName =
            "MyPerformanceCounter";
         CounterCreationData^ myCounterCreation = gcnew CounterCreationData;
         myCounterCreation->CounterName = "MyCounter";
         myCounterCreation->CounterHelp = "Counter Help";
         // Add a counter to collection of  myPerformanceCounterInstaller.
         myPerformanceCounterInstaller->Counters->Add( myCounterCreation );
         Installers->Add( myPerformanceCounterInstaller );
      }
      catch ( Exception^ e ) 
      {
          this->Context->LogMessage( "Error occurred : " + e->Message );
      }
   }
};

Remarks

The following information might help provide a performance improvement when installing performance counters at application startup. Performance counter categories installed with .NET Framework version 2.0 use separate shared memories, with each performance counter category having its own memory. You can specify the size of separate shared memory by creating a DWORD named FileMappingSize in the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<category name>\Performance. The FileMappingSize value is set to the shared memory size of the category. The default size is 131072 decimal. If the FileMappingSize value is not present, the fileMappingSize attribute value for the performanceCounters element specified in the Machine.config file is used, causing additional overhead for configuration file processing. You can realize a performance improvement for application startup by setting the file mapping size in the registry.
