/proc/[pid]/status

              Provides much of the information in /proc/[pid]/stat and

              /proc/[pid]/statm in a format that's easier for humans to

              parse.  Here's an example:

              * NStgid : Thread group ID (i.e., PID) in each of the PID

                namespaces of which [pid] is a member.  The leftmost entry

                reading process, followed by the value in successively

                nested inner namespaces.  (Since Linux 4.1.)

              * NSpid: Thread ID in each of the PID namespaces of which

                [pid] is a member.  The fields are ordered as for NStgid.

              * VmPeak: Peak virtual memory size.

              * VmSize: Virtual memory size.

              * VmLck: Locked memory size (see mlock(3)).

                pages that can't be moved because something needs to

                directly access physical memory.

              * VmHWM: Peak resident set size ("high water mark").

              * VmRSS: Resident set size.  Note that the value here is the

                sum of RssAnon, RssFile, and RssShmem.

              * RssAnon: Size of resident anonymous memory.  (since Linux

                4.5).

                shared memory, mappings from tmpfs(5), and shared anonymous

                mappings).  (since Linux 4.5).

              * VmData, VmStk, VmExe: Size of data, stack, and text seg‐

                ments.

              * VmLib: Shared library code size.

              * VmPTE: Page table entries size (since Linux 2.6.10).

              * VmPMD: Size of second-level page tables (since Linux 4.0).

              * VmSwap: Swapped-out virtual memory size by anonymous private

                pages; shmem swap usage is not included (since Linux

                2.6.34).

              * HugetlbPages: Size of hugetlb memory portions.  (since Linux

                4.4).

              * Threads: Number of threads in process containing this

                thread.

              * SigQ: This field contains two slash-separated numbers that

                relate to queued signals for the real user ID of this

                process.  The first of these is the number of currently

                queued signals for this real user ID, and the second is the

                resource limit on the number of queued signals for this

                process (see the description of RLIMIT_SIGPENDING in

                getrlimit(2)).

              * SigPnd, ShdPnd: Number of signals pending for thread and for

                process as a whole (see pthreads(7) and signal(7)).

              * SigBlk, SigIgn, SigCgt: Masks indicating signals being

                blocked, ignored, and caught (see signal(7)).

              * CapInh, CapPrm, CapEff: Masks of capabilities enabled in

                inheritable, permitted, and effective sets (see

                capabilities(7)).

              * CapBnd: Capability Bounding set (since Linux 2.6.26, see

                capabilities(7)).

              * CapAmb: Ambient capability set (since Linux 4.3, see

                capabilities(7)).

              * NoNewPrivs: Value of the no_new_privs bit (since Linux 4.10,

                see prctl(2)).

              * Seccomp: Seccomp mode of the process (since Linux 3.8, see

                seccomp(2)).  0 means SECCOMP_MODE_DISABLED; 1 means SEC‐

                COMP_MODE_STRICT; 2 means SECCOMP_MODE_FILTER.  This field

                is provided only if the kernel was built with the CON‐

                FIG_SECCOMP kernel configuration option enabled.

              * Cpus_allowed: Mask of CPUs on which this process may run

                (since Linux 2.6.24, see cpuset(7)).

              * Cpus_allowed_list: Same as previous, but in "list format"

                (since Linux 2.6.26, see cpuset(7)).

              * Mems_allowed: Mask of memory nodes allowed to this process

                (since Linux 2.6.24, see cpuset(7)).

              * Mems_allowed_list: Same as previous, but in "list format"

                (since Linux 2.6.26, see cpuset(7)).

              * voluntary_ctxt_switches, nonvoluntary_ctxt_switches: Number

                of voluntary and involuntary context switches (since Linux

                2.6.23).
