Previously, to report the Virtual size of a process Windows agent used metric 'VirtualSize' from WMI counter 'Win32_Process'. Unfortunately, in Windows this metric means not the Virtual size of process but the size of the process virtual address space, usually 2TB for 32-bit application. As a result monitoring information related to the process Virtial size was useless.
Since this release, Windows agent uses 'Commit Charge' Win32 metric to correctly report the Virtual size of a process, thus solving the problem. 'Commit Charge' is the total amount of virtual memory of a process that must be backed by either physical memory or the page file.
