## Penggunaan

### To Display Basic System Information

To display basic system information, select the System tab.

In the System tab, information is organized into three groups:

- System Information

- Perkakasan

- Status Sistem

### To Display the Process List

To display the process list, select the Processes tab.

In the Processes tab, the processes are organized as a table. The rows of the table display information about the processes. The columns represent information fields for the processes, such as the name of the user who owns the process, the amount of memory currently being used by the process, and so on. From left to right, the Processes tab displays the following columns by default:

- Nama Proses

- Status

- %CPU

- Elok

- ID

- Ingatan

For information about how to change the columns displayed in the process list, see .

#### Parent Processes and Child Processes

A parent process is a process that spawns another process. The spawned process is a child process of the original parent process. By default, System Monitor does not show process dependencies. For information about how to change the default display behavior, see .

#### Process Priority and Nice Values

Processes run in order of priority: high-priority processes run before low-priority processes. Child processes generally inherit their priority from their parent process.

The priority of a process is set by the nice value of the process, as follows:

- A nice value of 0 means that the process has normal priority.

- The higher the nice value, the lower the priority.

- The lower the nice value, the higher the priority.

For information about how to change the priority of a process, see .

### To Sort the Process List

To sort the process list, perform the following steps:

1. Select the Processes tab to display the process list.

2. By default, the processes are listed by name, in alphabetical order. To list the processes in reverse alphabetical order, click on the Process Name column header.

3. Click on any column header to sort the processes by the information in that column, in alphabetical or numerical order.

4. Click again on the column header to sort the data in reverse alphabetical or reverse numerical order.

### To Modify the Contents of the Process List

You can modify the contents of the process list in several ways.

#### To Show All Processes

To show all processes in the process list, perform the following steps:

1. Select the Processes tab to display the process list.

2. Choose View All Processes .

#### To Show Only Processes Owned by the Current User

To show only the processes that are owned by the current user, perform the following steps:

1. Select the Processes tab to display the process list.

2. Choose View My Processes .

#### To Show Only Active Processes

To show only the active processes in the process list, perform the following steps:

1. Select the Processes tab to display the process list.

2. Choose View Active Processes .

#### To Show Dependencies

To show process dependencies in the process list, perform the following steps:

1. Select the Processes tab to display the process list.

2. Choose View Dependencies.

If the Dependencies menu item is selected, the processes are listed as follows:

- Parent processes are indicated by a triangle symbol to the left of the process name. Click on the triangle symbol to show or hide the associated child processes.

- Child processes are indented, and listed with their parent process.

If the Dependencies menu item is not selected:

- Parent processes and child processes are not distinguishable.

- All processes are listed in alphabetical order.

### To Display Memory Maps for a Process

To display memory maps for a process, perform the following steps:

1. Select the Processes tab to display the process list.

2. Select the process in the process list.

3. Choose View Memory Maps.

The Memory Maps dialog displays the information in tabular format. The name of the process is displayed above the memory-map table. From left to right, the Memory Maps dialog displays the following columns:

Filename

  The location of a shared library that is currently used by the process. If this field is blank, the memory information in this row describes memory that is owned by the process whose name is displayed above the memory-map table.

VM Start

  The address at which the memory segment begins.

VM End

  The address at which the memory segment ends.

VM Size

  The size of the memory segment.

Flags

  The following flags describe the different types of memory-segment access that the process can have:

  p

    The memory segment is private to the process, and is not accessible to other processes.

  r

    The process has permission to read from the memory segment.

  s

    The memory segment is shared with other processes.

  w

    The process has permission to write into the memory segment.

  x

    The process has permission to execute instructions that are contained within the memory segment.

VM Offset

  The virtual memory offset of the memory segment.

Device

  The major and minor device numbers of the device on which the shared library filename is located.

Inode

  The inode on the device from which the shared library location is loaded into memory.

Click on any column header to sort the data by the information in that column, in alphabetical or numerical order. Click again on the column header to sort the data in reverse alphabetical or reverse numerical order.

Click Close to close the Memory Maps dialog.
