Linux process status in the Kubernetes environment

On Linux, the State field in the /proc/[pid]/status file displays the current state of the process. The meanings of each status are as follows:

Code	Description
R (Running)	The process is running or ready to run.
S (Sleeping)	Interruptible sleep state, waiting for an event.
D (Disk Sleep)	Non-interruptible sleep state, waiting for an I/O operation.
R (Zombie)	The process has been terminated, but the parent process has not yet collected its termination status.
T (Stopped)	The process is stopped by a job control signal (such as SIGSTOP) or debugger.
t (Tracing stop)	Tracing stopped - State being traced by the debugger (indicated by a lowercase t)
X (Dead)	Dead state - The process is dead (commonly unseen)
x (Dead)	Dead state - The kernel thread is dead (commonly unseen)
K (WakeKill)	Forcibly terminated - It ignores any wakeup signal and is immediately dead.
W (Waking)	Waking up - State of being woken up after receiving a wake-up signal
I (Idle)	Kernel thread is idle (usually invisible to user space processes).

Note

Because Kubernetes manages the resources of containers and nodes efficiently, many processes running in containers are actually in waiting state. As a result, most processes may be in Sleeping state.
