How to check Process Identifier (PID) for a running process


The default arrangement of columns on the Processes tab does not include the Process Identifier (PID) column. Determining what processes are already running can be an important step in troubleshooting.

However, for detailed troubleshooting and performance analysis, we recommend that you display the Process ID (PIS) column on the Processes tab. 

There are two ways to check the PID for running processes:

1. Using Task Manager

2. Using Command Prompt

1. Using Task Manager

Ø Open the task manager

Ø Go to Process tab

Ø In the menu, click View à Select Columns


Ø Select PID (Process Identifier) checkbox


Ø A new column PID would be added to the Process tab


2. Using Command Prompt

Ø Open the command prompt (Run as Administrator)

Ø Run the command tasklist

Ø The list of all running processes with the PIDs will be listed.

Mac OSX:

The command ps (entered on the command line in a Terminal window) with a variety of flags can give information on what is running for the user, the process id, the parent process id, and so forth.

ps -ax

The flags can be used individually or combined. For instance, ps -alx is commonly used to view system processes and their parent process ids. For more information, consult the System Reference Manual by typing the following command at the Terminal prompt:

man ps
