I'm recently started studying RHEL. But I'm not sure, what does vmstat column "r" mean?
- does it include kernel and user thread? or only kernel thread?
- does vmstat command read /proc/stat or traversal /proc//stat?
Because for AIX, I know are response for only kernel thread (kernel thread or kmt thread). But for RHEL, the man page only show " r: The number of processes waiting for run time."
