oom OOM Out of Memory Score. The value, ranging from 0 to
+1000, used to select task(s) to kill when memory
is exhausted.
oomadj OOMADJ Out of Memory Adjustment Factor. The value is
added to the current out of memory score which is
then used to determine which task to kill when
memory is exhausted.
ouid OWNER displays the Unix user identifier of the owner of
the session of a process, if systemd support has
been included.
pcpu %CPU see %cpu. (alias %cpu).
pending PENDING mask of the pending signals. See signal(7).
Signals pending on the process are distinct from
signals pending on individual threads. Use the m
option or the -m option to see both. According to
the width of the field, a 32 or 64 bits mask in
hexadecimal format is displayed. (alias sig).
pgid PGID process group ID or, equivalently, the process ID
of the process group leader. (alias pgrp).
pgrp PGRP see pgid. (alias pgid).
pid PID a number representing the process ID (alias tgid).
pidns PIDNS Unique inode number describing the namespace the
process belongs to. See namespaces(7).
pmem %MEM see %mem. (alias %mem).
policy POL scheduling class of the process. (alias
class, cls). Possible values are:
- not reported
TS SCHED_OTHER
FF SCHED_FIFO
RR SCHED_RR
B SCHED_BATCH
ISO SCHED_ISO
IDL SCHED_IDLE
DLN SCHED_DEADLINE
? unknown value
ppid PPID parent process ID.
pri PRI priority of the process. Higher number means
higher priority.
psr PSR processor that process last executed on.
pss PSS Proportional share size, the non‐swapped physical
memory, with shared memory proportionally
accounted to all tasks mapping it.
rbytes RBYTES Number of bytes which this process really did
cause to be fetched from the storage layer.
rchars RCHARS Number of bytes which this task has caused to be
read from storage.
rgid RGID real group ID.
rgroup RGROUP real group name. This will be the textual group
ID, if it can be obtained and the field width
permits, or a decimal representation otherwise.
rops ROPS Number of read I/O operations—that is, system
calls such as read(2) and pread(2).
rss RSS resident set size, the non-swapped physical memory
that a task has used (in kiloBytes). (alias
rssize, rsz).
rssize RSS see rss. (alias rss, rsz).
rsz RSZ see rss. (alias rss, rssize).
rtprio RTPRIO realtime priority.
ruid RUID real user ID.
ruser RUSER real user
