Available Bytes Counter Definition is Incorrect in Perfmon (184063)
The information in this article applies to:
- Microsoft Windows NT Server 4.0
- Microsoft Windows NT Workstation 4.0
This article was previously published under Q184063 SUMMARY
The counter definition in Performance Monitor for the object Memory and
counter Available Bytes incorrectly states that:
Available Bytes displays the size of the virtual memory currently on the
Zeroed, Free, and Standby lists. Zeroed and Free memory is ready for
use, with Zeroed memory cleared to zeros. Standby memory is memory
removed from a process's Working Set but still available. Notice that
this is an instantaneous count, not an average over the time interval.
The counter definition should read as follows:
Available Bytes is the amount of physical memory available to processes
running on the computer, in bytes. It is calculated by summing space on
the Zeroed, Free, and Standby memory lists. Free memory is ready for
use; Zeroed memory is pages of memory filled with zeros to prevent later
processes from seeing data used by a previous process. Standby memory is
memory removed from a process's working set (its physical memory) on
route to disk, but is still available to be recalled.
This information can be found in the Counters.hlp file, part of the Windows
NT Workstation 4.0 Resource Kit.
