IV. UTILITIES & DRIVERS
Using Perfmon for Performance Monitoring
The Perfmon utility is found in the "Administrative Tools" program group. It can be
run either locally or across the network. The best option is to run the utility on a
remote machine across a network. This allows the full screen of the local machine to
be used to display the 3D application. Also, since displaying the graphs for the perfmon
output is done by the display driver, running perfmon locally will impact the perfor-
mance of the 3D application being measured. When running remotely, the only over-
head is some network traffic every probe interval (by default once a second).
Running perfmon locally
•
Start the Perfmon utility from the Administrative Tools program group.
•
From the Edit menu choose "Add to Chart ..."
•
The Object field provides a sorted scrollable list. Choose the GLINT object.
•
In the Counter field the GLINT counters described above will be listed.
•
Choose "% GLINT busy" and press the "Add" button. Then press the "Done"
button (when "Add" has been pressed the "Cancel" button turns into the "Done"
button).
•
A graph will be added which indicates how busy the GLINT chip is. Initially,
this will be zero since there are no 3D interrupt driven DMA applications run-
ning.
•
Start a 3D OpenGL application such as one of the standard demos provided
with the release. The GLINT busy graph will start to register. Sampling is once
every second by default.
•
To add new counters repeat the steps by choosing "Add to Chart ..." from the
Edit menu.
Running perfmon remotely
Perfmon can be run on a remote machine connected to a machine with a GLINT
card over a network. The remote machine does not need a GLINT card but must be
running Windows NT. The remote machine is used solely for displaying the graphi-
cal output of the Perfmon utility. Permon takes care of sampling the GLINT counters
via a network connection.
Running Perfmon remotely
•
On the remote machine, start the Perfmon utility from the Administrative Tools
program group.
•
In the Computer field, press the button labelled "..." or if you know the name
of the machine on which the GLINT installed type \HOSTNAME" where the
hostname is the network name of the GLINT machine. After typing the name
press Return.
•
If the "..." button is used then a standard network dialog will be displayed.
Choose the remote machine in the usual way.
•
You are now connected to the GLINT machine. Continue in the same way as
for the local procedure described above.
