Title: Windows agent reports Virtual Size correctly
Component: Checks & agents
Level: 1
Class: Bug fix
Version: 2.2.0i1
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.
