Performance Tool

The Performance tool is used to monitor resource utilization. Resource utilization can be summarized for the system, viewed by project, or viewed for an individual user.

Figure 15-1 Performance Tool in the Solaris Management Console

Screen capture shows Performance under Management Tools in Navigation pane and summary of system performance Attribute and Value pane.

How to Access the Performance Tool

The Performance tool is located under System Status in the Navigation pane. To access the Performance tool, do the following:

Click the System Status control entity in the Navigation pane.
The control entity is used to expand menu items in the Navigation pane.
Click the Performance control entity.
Click the System control entity.
Double-click Summary, Projects, or Users.
Your choice depends on the usage you want to monitor.
