This chapter describes the resource control and performance monitoring features in the Solaris Management Console. Only a subset of the resource management features can be controlled using the console.You can use the console to monitor system performance and to enter the resource control values shown in Table 15–1 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.The following topics are covered.Using the Console (Task Map) Console Overview Management Scope Performance Tool Resource Controls Tab Console References 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. How to Access the Performance Tool Add resource controls to projects Access the Resource Controls tab under System Configuration. How to Access the Resource Controls Tab 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 Chapter 2, Working With the Solaris 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. 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 that you select during a console session should correspond to the primary name service that is identified in the /etc/nsswitch.conf file. 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.

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

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. Values are shown for the following attributes.Attribute Description Active Processes Number of processes that are active on the system Physical Memory Used Amount of system memory that is in use Physical Memory Free Amount of system memory that is available Swap Used Amount of system swap space that is in use Swap Free Amount of free system swap space Page Rate Rate of system paging activity System Calls Number of system calls per second Network Packets Number of network packets that are transmitted per second CPU Usage Percentage of CPU that is currently in use Load Average Number of processes in the system run queue which are averaged over the last 1, 5, and 15 minutes Values are shown for the following attributes.Attribute Short Name Description Input Blocks inblk Number of blocks read Blocks Written oublk Number of blocks written Chars Read/Written ioch Number of characters read and written Data Page Fault Sleep Time dftime Amount of time spent processing data page faults Involuntary Context Switches ictx Number of involuntary context switches System Mode Time stime Amount of time spent in the kernel mode Major Page Faults majfl Number of major page faults Messages Received mrcv Number of messages received Messages Sent msend Number of messages sent Minor Page Faults minf Number of minor page faults Num Processes nprocs Number of processes owned by the user or the project Num LWPs count Number of lightweight processes Other Sleep Time slptime Sleep time other than tftime, dftime, kftime, and ltime CPU Time pctcpu Percentage of recent CPU time used by the process, the user, or the project Memory Used pctmem Percentage of system memory used by the process, the user, or the project Heap Size brksize Amount of memory allocated for the process data segment Resident Set Size rsssize Current amount of memory claimed by the process Process Image Size size Size of the process image in Kbytes Signals Received sigs Number of signals received Stopped Time stoptime Amount of time spent in the stopped state Swap Operations swaps Number of swap operations in progress System Calls Made sysc Number of system calls made over the last time interval System Page Fault Sleep Time kftime Amount of time spent processing page faults System Trap Time ttime Amount of time spent processing system traps Text Page Fault Sleep Time tftime Amount of time spent processing text page faults User Lock Wait Sleep Time ltime Amount of time spent waiting for user locks User Mode Time utime Amount of time spent in the user mode User and System Mode Time time The cumulative CPU execution time Voluntary Context Switches vctx Number of voluntary context switches Wait CPU Time wtime Amount of time spent waiting for CPU (latency) 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.

Screen capture shows the Resource Controls tab. Resource controls and their values appear on the 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. The following table shows the resource controls that can be set in the console. The table describes the resource that is constrained by each control. The table also identifies the default units that are used by the project database for that resource. The default units are of two types:Quantities represent a limited amount. Indexes represent a maximum valid identifier. Thus, project.cpu-shares specifies the number of shares to which the project is entitled. process.max-file-descriptor specifies the highest file number that can be assigned to a process by the open2 system call.Control Name Description Default Unit project.cpu-shares The number of CPU shares that are granted to this project for use with the fair share scheduler (FSS) (see the FSS7 man page) Quantity (shares) task.max-cpu-time Maximum CPU time that is available to this task's processes Time (seconds) task.max-lwps Maximum number of LWPs simultaneously available to this task's processes Quantity (LWPs) process.max-cpu-time Maximum CPU time that is available to this process Time (seconds) process.max-file-descriptor Maximum file descriptor index that is available to this process Index (maximum file descriptor) process.max-file-size Maximum file offset that is available for writing by this process Size (bytes) process.max-core-size Maximum size of a core file that is created by this process Size (bytes) process.max-data-size Maximum heap memory that is available to this process Size (bytes) process.max-stack-size Maximum stack memory segment that is available to this process Size (bytes) process.max-address-space Maximum amount of address space, as summed over segment sizes, available to this process Size (bytes) You can view, add, edit, or delete resource control values for processes, projects, and tasks. These operations are performed through dialog boxes in the console.Resource controls and values are viewed in tables in the console. The Resource Control column lists the resource controls that can be set. The Value column displays the properties that are associated with each resource control. In the table, these values are enclosed in parentheses, and they appear as plain text separated by commas. The values in parentheses comprise an “action clause.” Each action clause is composed of a threshold, a privilege level, one signal, and one local action that is associated with the particular threshold. Each resource control can have multiple action clauses, which are also separated by commas.On a running system, values that are altered in the project database through the console only take effect for new tasks that are started in a project. For information on projects and tasks, see Chapter 2, Projects and Tasks (Overview). For information on resource controls, see Chapter 6, Resource Controls (Overview). For information on the fair share scheduler (FSS), see Chapter 8, Fair Share Scheduler (Overview).Not all resource controls can be set in the console. See Table 15–1 for the list of controls that can be set in the console.
