What exactly is recorded about the current running processes in the system?

The following information is usually recorded about currently running processes in the system:

• PID (Process ID): a unique identifier of the process.
• Process name: the name of the executable program.
• Process status: for example, running, waiting, stopped.
• Resource usage: amount of memory, CPU, runtime.
• Process owner: the user under which the process is running.
• File descriptors: open files and sockets.
• Parent process (PPID): the identifier of the parent process.

This data allows system administrators and monitoring tools to track the state and behavior of processes, identify problems, and optimize system performance.
