Keeping tabs on system resources is not something most people need to
fret about on a daily basis. However, if your machine is running low on
random access memory (RAM) or involved in resource-intensive operations,
you may want to check a few pertinent statistics from time to time.
Windows 95 and Windows 98 (Win9x) include a couple of basic monitoring
programs: System Resource Meter and System Monitor. However, these two
tools are not always included during operating system setup. If you
don’t see System Resource Meter and System Monitor when you click Start, select
Programs, Accessories, and System Tools; they are easy to
install, assuming you have the Windows installation CD-ROM.

Just go to
the Control Panel under the Start Menu’s Settings option, click
Add/Remove Programs, and then the Windows Setup tab. Scroll down to
System Tools, click the Details button, and put check marks next to the
two programs.

Keep clicking OK to finish up.
System Resource Meter.
System Resource Meter is a relatively simple program that keeps track of
a few basic indicators of your system’s performance. When the meter is
running, a small icon that looks like four small green lights resides in
the Taskbar. As the lights disappear, your system is using more and more
resources. When only one light is left, the indicator turns from green
to red to let you know resources must be freed to avoid “insufficient
memory” errors that could cause data loss in some situations.
There are a couple of ways to see a more detailed view of the data
System Resource Meter tracks. A quick method is to let the mouse pointer
momentarily hover over the Taskbar indicator. A pop-up box appears with
specific percentages relating to several resource types.

Double-clicking
the resource indicator brings up a larger version of this graph.

Both the tiny pop-up and larger bar graphs show three measurements:
system resources, user resources, and graphics device interface (GDI)
resources. These three critical memory areas are limited in size no
matter how much RAM a machine has for reasons that go all the way back
to the dark days of DOS. If one of these indicators drops below 50%,
your system can start to seem sluggish. Closing open windows and
programs will generally free up resources, although some programs may
refuse to hand back the memory they were using.
System Monitor.
System Monitor is a fancier version of System Resource Meter that will
track a much larger range of resource indicators, as well as let you
view changes in usage over time. A good way to figure out how to use
this resource meter is to open up the program and start experimenting.

Unlike System Resource Meter, the System Monitor does not live in the
Taskbar but rather presents its own window full of information. To pick
among the available charts, go to the Edit menu and choose Add Item.
Categories of charts line the left side of the screen while individual
choices in each category are displayed on the right side. You can add
more than one chart at a time by holding CTRL while clicking the
different items. Click the Explain button to see details about a
particular type of chart. To begin seeing the charts in action, click
OK.
All of the different statistics will parade across your window in three
ways according to your preference. Line charts are the best for watching
resources ebb and flow. Bar charts give you a quick view of the data
along with maximum values. Numeric charts forego the graphics for a more
exact representation. You can switch from one type of view to the other
by clicking the different buttons on the toolbar. One key to
understanding the line charts is to realize the scale automatically
changes as the values increase or decrease, so glance at the axis to see
just what you are looking at. It is possible to switch to a fixed scale
in the Edit Item command under the Edit menu.

Other Tools.
Another quick way to get a snapshot of your computer’s free
resources is to right-click My Computer, select Properties
and choose the Performance tab
in the box that appears. Beneath the amount of total memory installed is
the percentage of overall system resources that are free. Windows 98
also includes a program called System Information (When you click
Start, select Programs, Accessories, and System
Tools) that provides this and other information.

For a more detailed view of how your computer is performing, use a monitoring program, such as Symantec’s Norton Utilities. This
comprehensive package gives information on every measurement
of system resources imaginable.
