Processes Page

The Processes page lists the processes currently running on the Unix system.

Note: The Processes page shows the output from the Unix ps command.

To open the Processes page

Select the Spotlight on Unix connection in the Spotlight Browser.
Click Processes | Processes.

For each process, you can view the information that follows:

Notes:

Some columns in the table are hidden by default. To view hidden columns, right-click a column heading and choose Organize Columns... from the shortcut menu.
Refer to man ps(1) for further details on the values shown in the Processes grid.
When the table is displayed as a flat grid (not a tree), right click any value in the table and select Show processes where... or Hide processes where... to filter the table by that value.

Column

Description

Process

The name of the process.

Notes:

Click on a process to display more information on that process. Process Details Page
Right click on the process and select Kill Process (if enabled) to end any processes currently running on the Unix machine.
Some of the processes may be running other, secondary, processes. Right click the grid and select Show as Tree to display the secondary processes as branches of the initial process.

Nice

The Nice value describes the relative priority of the specified process. A process with a low Nice value is running at a higher priority than a process with a high Nice value.

PID

The process identifier for the specified process.

PPID

The process identifier for the process that is the parent of the specified process.

% CPU

The percentage of CPU time used by the process in the last sample interval.

State

The state of the process. Process states are platform dependent.

Platform	Value	Description
AIX	A	Active
	W	Swapped
	I	Idle
HP-UX	W	Waiting
	I	Intermediate
	X	Growing
Linux	D	Uninterruptible Sleep
	W	Has no resident pages
	<	High priority process
	N	Low priority tasks
	L	Has pages locked into memory
Solaris	O	Process is running on a processor
	S	Sleeping. That is, the process is waiting for an event to complete.
	R	Runnable. That is, the process is on the run queue.
	Z	Zombie state. That is, the process has been terminated and the parent process is no longer waiting.
	T	The process has been stopped by a job control signal, or because it is being traced.

Terminal

The Unix terminal session where a user started the specified process. If the process was not started by an interactive user, the Terminal value is set to "?".

User

The name of the user to whom the process belongs.

Time

The amount of CPU time the process has consumed.

Virt Mem (MB)

The amount of virtual memory in use by the process, measured in megabytes.

Process Details Page

The Process Details page contains a detailed list of properties for the process selected on the Processes page.

To open the Process Details page

Select the Spotlight on Unix connection in the Spotlight Browser.
Click Processes | Processes.
Select a process to view its details

For the selected process

The Memory Usage chart displays data series for the virtual memory and physical memory used by the selected process.

The CPU Usage chart displays CPU usage for the selected process.

The information grid is as follows.

Item

Description

Process

The name of the process.

Process ID

The process identifier for the specified process.

User

The name of the user to whom the process belongs.

Parent PID

The process identifier for the process that is the parent of the specified process.

Group ID

The group identifier for the user that owns the specified process.

Processor %

The percentage of CPU time used by the process in the last sample interval.

Elapsed Time

How long the process has been running.

Cumulative Time

The amount of CPU time the process has consumed.

State

The state of the process. Process states are platform dependent.

	T	The process has been stopped by a job control signal, or because it is being traced.

Terminal

The Unix terminal session where a user started the specified process. If the process was not started by an interactive user, the Terminal value is set to "?".

Priority

The basic priority assigned to the process – the lower the number, the higher the priority. Unix can modify this priority by means of the renice command.

Nice

The Nice value describes the relative priority of the specified process. A process with a low Nice value is running at a higher priority than a process with a high Nice value.

Virt Mem (MB)

The amount of virtual memory in use by the process, measured in megabytes.

Physical Mem (MB)

The amount of physical memory in use by the process, measured in megabytes.

Command

The command executed by the process.
