Chapter 20Using Performance Meter
Use the Performance Meter to monitor activity and performance
on a workstation. Several performance parameters such as CPU utilization,
disk activity, network packets, and the like, can be displayed graphically
in this customizable window.
You can monitor performance of local or remote hosts, set up color-coded
activity thresholds to warn you of exceptional performance, and log the samples
to a file.
Tip - Performance Meter enables you to identify errant behavior on your
system. After identifying the errant behavior, you can use Process Manager
(see Chapter 19, Using Process Manager) to identify and kill the errant
processes.
To Open Performance Meter
Click the Performance Meter control on the Font Panel. Performance Meter opens and displays the default charts (CPU and disk
activity).
Tip - To make Performance Meter's Front Panel icon inactive, use Process
Manager to kill the sdtperfmeter process.
Choosing the Host and Parameters to Display
You can monitor performance on your workstation (local) or on another
workstation (remote). The View menu lists several performance parameters that
you can display for the host you are monitoring.
 The parameters you choose to monitor may depend on:
Users unfamiliar with system parameters will typically choose to display
CPU and disk usage. The typical setup for a more aware user is to display
the CPU usage, disk usage, system load, and packets. Here are some hints and
tips for choosing what to monitor:
If you are worried about network traffic congestion, display
the number of network packets per second and monitor this performance while
you are running network-intensive activities such as Internet browsing or
remote operations.
If Performance Meter indicates high CPU usage, use Process
Manager to identify and kill errant or CPU-intensive processes.
If you log out while running a CPU intensive application,
and log back in, Performance Meter's CPU display may show you that there is
a lot of CPU activity. On recognizing this, you can use Process Manager to
kill any errant processes.
For further information, see Managing System
Performance in System Administration Guide: Advanced Administration.
To Specify the Host to Be Monitored
Choose Setup from the Options menu. Performance Meter displays the Setup dialog box.
Select the Remote radio button to indicate that you are about to type
the name of a remote host.
Type the system name (for example, jupiter)
or the IP address (for example, 129.156.220.133)
of the remote host.
Tip - To find a host, use Address Manager with Hosts selected on the
Find menu.
Click Apply to make your changes take effect. Performance Meter accesses the remote host and displays its performance.
The system name on the title bar of the Performance Meter main window changes
to the name of the remote host.
To Change the Parameters Displayed
Open the View menu to display the list of available parameters. Each parameter has a checkbox to indicate whether it is currently selected
for display.
Select or deselect the relevant menu item to display or remove any of
the parameters. You can display any combination of parameters.
Choosing How the Parameters Are Displayed
You can arrange the Performance Meter window in different ways, depending
on the number of parameters you have chosen to display, the space available
on your desktop, and whether you want to display historical values.
