Resource Control Functionality in the Solaris Management Console
This chapter describes the resource control and performance monitoring features in the Solaris Management Console.
You can use the console to monitor system performance and to enter resource control values for projects, tasks, and processes. The console provides a convenient, secure alternative to the command-line interface (CLI) for managing hundreds of configuration parameters that are spread across many systems. Each system is managed individually. The console's graphical interface supports all experience levels.
Using the Console (Task Map)
Task | Description | For Instructions |
|---|---|---|
Use the console | Start the Solaris Management Console in a local environment or in a name service or directory service environment. Note that the performance tool is not available in a name service environment. | "Starting the Solaris Management Console" in System Administration Guide: Basic Administration and "Using the Solaris Management Tools in a Name Service Environment (Task Map)" in System Administration Guide: Basic Administration |
Monitor system performance | Access the Performance tool under System Status. | |
Add resource controls to projects | Access the Resource Controls tab under System Configuration. |
Overview
Resource management functionality is a component of the Solaris Management Console. The console is a container for GUI-based administrative tools that are stored in collections called toolboxes. For information on the console and how to use it, see "Working With the Management Console (Tasks)" in System Administration Guide: Basic Administration.
When you use the console and its tools, the main source of documentation is the online help system in the console itself. For a description of the documentation available in the online help, see "Solaris Management Console (Overview)" in System Administration Guide: Basic Administration.
Management Scope
The term management scope refers to the name service environment that you choose to use with the selected management tool. The management scope choices for the resource control and performance tools are the/etc/project local file, or NIS.
The management scope you select during a console session should correspond to the primary name service that is identified in the /etc/nsswitch.conf file.
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 12-1 Performance Tool in the Solaris Management Console
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.

Resource Controls Tab
Resource controls allow you to associate a project with a set of resource constraints. These constraints determine the allowable resource usage of tasks and processes that run in the context of the project.

How to Access the Resource Controls Tab
The Resource Controls tab is located under System Configuration in the Navigation pane. To access Resource Controls, do the following:
Click the System Configuration control entity in the Navigation pane.
Double-click Projects.
Click on a project in the console main window to select it.
Select Properties from the Action menu.
Click the Resource Controls tab.
View, add, edit, or delete resource control values for processes, projects, and tasks.
