Performance Monitor Reports Wrong Percent of Free Disk Space

ID: Q141833

The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.5, 3.51
  • Microsoft Windows NT Server versions 3.5, 3.51

SYMPTOMS

Performance Monitor reports the percent of free disk space incorrectly when used on a system with a different number of physical disks than the system where the workspace was originally created.

Steps to Reproduce Problem

  1. Go to a machine with one physical disk.


  2. Using Performance Monitor, create a workspace in the alert log.


  3. Add the counter %freespace to that log and make it <20% for drive 'C', parent '0'.


  4. Save the workspace.


  5. Load the saved workspace in Performance Monitor on a system with two or more physical drives.


The % of disk space is reported as 0% instead of the correct value and the parent physical disk is reported as '--' instead of '0'. Performance monitor continues to generate event log entries at the specified interval reporting disk space at 0%.


CAUSE

Performance monitor does not correctly translate workspace settings for disk space between two machines with a different number of physical disks.


WORKAROUND

Create the workspace on each machine that has a different number of physical disks. Performance monitor will then report correct percent of free disk space for that system.


STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
