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

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

  3. 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.

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 "?".
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.

Zombies Page

Unix expects a parent process to acknowledge the termination of any child process. If it fails to do so, the terminated child process is classified by the kernel as a zombie.

A high number of zombie processes indicates that one or more processes are not handling their child processes properly. You may need to kill the parent process to eliminate its zombie child process.

To open the Zombies page

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

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

Column Description
PID The process identifier for the specified process.
PPID The process identifier for the process that is the parent of the specified process.
UID The user identifier for the user to whom the process belongs.
State Z for Zombie. That is, the process has been terminated and the parent process is no longer waiting.
Priority The basic priority assigned to the process – the lower the number, the higher the priority.
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.
CPU Utilization A value representing the amount of CPU time used by the process. The metric used here may differ across Unix implementations.
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 "?".
Command The command executed by the process.

Services page

The Services page lists (by name) the popular services found in the /etc/services file of the Unix machine. These services may or may not be enabled.

To open the Services page

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

The Services table contains the following information.

Column Description
Service name The name of the specified service.
Port number The logical port used by the service to handle data.
Protocol The transfer protocol used by the service. Possible protocols include TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
Aliases Alternative names for the service.
Active?

The status of the port used by the service (initially blank).

To display the status, right-click on a service in the table and select Test port. Possible values are:

  • Yes - A process on the server is listening on that port.
  • No - There is no process listening on that port.
  • Connecting... - Spotlight is waiting for a response from the server.
