Question 2011 Scripting Games : Advanced Event 4

Bonsoir,

Ci-après le script que j'ai posté lors des Scripting Games 2011, dans le cadre de l'Advanced Event 4.

Le scénario était le suivant :

You are the network administrator for a large company with multiple locations around the world. Your performance team has expressed concern with the large amount of memory that is consumed by one particular instance of the SvcHost process. To investigate this process, the team lead has requested that you write a Windows PowerShell script that will list each instance of the SvcHost process, the amount of committed memory, the number of page faults, and the command line that launched each SvcHost process. In addition, the lead requires that the script list each service that is running inside each instance of the SvcHost process. An appropriate output from the script is shown in the following image.

Mon script (une solution) :
