VmPeakRepresents the peak memory occupies during the current process.
VmSizeRepresents the memory the process is now occupying
VmLckIt represents the size of physical memory that the process has locked. The locked physical memory cannot be exchanged to the hard disk.
VmHWMIt is the peak value that the program gets allocated to physical memory.
VmRSSIt is the physical memory used by the program now.
VmData: Indicates the size of the process data segment.
VmStk: Indicates the size of the process stack segment.
VmExe: Indicates the size of the process code.
VmLib: Indicates the size of the LIB library used by the process.
VmPTE:The size of the page table occupied.
VmSwap: The process takes up the Swap size.
Threads: Indicates the number of threads in the current process group.
SigPnd:Mask bit, stores the pending signal of the thread, which is equivalent to the PENDING signal of the thread.
ShnPnd: Mask bit, stores the pending signal of the thread group. It is equivalent to the PENDING signal of the process group.
SigBlk: Store blocked signals, which are equivalent to BLOCKED signals.
SigIgn: Stores ignored signals, which is equivalent to IGNORED signals.
SigCgt: Stores the captured signal, which is equivalent to the CAUGHT signal.
CapEff: When a process wants to perform a privileged operation, the operating system will check whether the corresponding bit of cap_effective is valid, instead of checking whether the valid UID of the process is 0.
CapPrm: Indicates the ability that a process can use. Cap_permitted can contain abilities that are not in cap_effective. These abilities are temporarily abandoned by the process itself. It can also be said that cap_effective is a subset of cap_permitted.
CapInh: Indicates the ability to inherit programs that can be executed by the current process.
CapBnd: It is the boundary capability of the system, we cannot change it.
Cpus_allowed:3 points out that the process can use the CPU affinity mask, because we specify it as two CPUs, so here is 3. If the process is specified as 4 CPUs (if there is any), here is F(1111).
Cpus_allowed_list:0-1 indicates that the process can use the CPU list, here is 0-1.
voluntary_ctxt_switchesIndicates the number of times the process actively switches.
nonvoluntary_ctxt_switchesIndicates the number of passive switching times of the process.
