L'exemple suivant montre comment utiliser la classe CounterCreationDataCollection. L’exemple crée une nouvelle instance de la classe et utilise plusieurs méthodes pour ajouter des instructions à la collection, retourner leur index et ajouter ou supprimer des attributs à un point d’index spécifique.

//    Description - This counter type shows how many items are processed, on average,
//        during an operation. Counters of this type display a ratio of the items 
//        processed (such as bytes sent) to the number of operations completed. The  
//        ratio is calculated by comparing the number of items processed during the 
//        last interval to the number of operations completed during the last interval. 
// Generic type - Average
//      Formula - (N1 - N0) / (D1 - D0), where the numerator (N) represents the number 
//        of items processed during the last sample interval and the denominator (D) 
//        represents the number of operations completed during the last two sample 
//        intervals. 
//    Average (Nx - N0) / (Dx - D0)
