Besides the automatic diagnostic tools mentioned in the previous few sections, Windows Vista comes with a new tool for monitoring your system yourself: the Windows Performance Diagnostic Console. You load this Microsoft Management Console snap-in by pressing Windows Logo+R, typing perfmon.msc, and clicking OK.

The console rootPerformance Diagnosticsdisplays the Resource Monitor, which is divided into six sections:

  • Resource Overview This section shows graphs of the data in the CPU, Disk, Network, and Memory sections.

  • CPU This section shows the percentage of CPU resources that your system is using. Click the downward-pointing arrow to expand the section and show the percentage of resources that each running process is using..

  • Disk This section shows the total hard disk I/O transfer rate (disk reads and writes in kilobytes per second). Expand the section to see the files involved in the current disk I/O operations.

  • Network This section shows the total network data-transfer rate (data sent and received in megabits per second). Expand the section to see the remote computers involved in the current network transfers.

  • Memory This section shows the average number of hard memory faults per second and the percentage of physical memory used. Expand the section to view the individual processes in memory, as well as the hard faults and memory used for each.

Note

A memory fault does not refer to a physical problem. Instead, it means that the system could not find the data it needed in the file system cache. If it then finds the data elsewhere in memory, this is called a soft fault; if the system has to go to the hard disk to retrieve the data, this is called a hard fault.
