Ubuntu Manpage: pcp-ps - Report statistics for Linux Process.

NAME

       pcp-ps - Report statistics for Linux Process.

SYNOPSIS

       pcp  [pcp options]  ps  [-e]  [-U  [username]]  [-V  --version]  [-c  Command name] [-P pid1,pid2..]  [-p
       pid1,pid2..]  [-o col1,col2... or ALL] [-Z timezone] [-z] [-?]

DESCRIPTION

       The pcp-ps command is used for monitoring individual  process  running  on  the  system.   Using  various
       options  it  helps  a user to see useful information related to the processes.  This information includes
       CPU percentage, memory and stack usage, scheduling and priority.  By default pcp-ps reports live data for
       the local host.

OPTIONS

When invoked via the pcp(1) command, the -h/--host, -O/--origin, -t/--interval, -Z/--timezone and several
other pcp options become indirectly available; refer to PCPIntro(1) for a complete description of these
options.

The additional command line options available for pcp-ps are:

-e Display all the process.
PID Process identifier.
TTY The terminal associated with the process.
TIME The cumulated CPU time in [DD-]hh:mm:ss format
(time=TIME).
CMD The task name along with its complete arguments.

-c [command name]
Display the real Command name of the tasks being monitored instead of the UID. If command name is
specified, then only tasks belonging to the specified command are displayed.

-U [username], --user-name[=username]
Display the real user name of the tasks being monitored instead of the UID. If username is
specified, then only tasks belonging to the specified user are displayed.

-V, --version
Print version number then exit.

-p pid1,pid2.., --pid-list=pid1,pid2..
Display only processes with the listed PIDs.

-P ppid1,ppid2.., --ppid-list=ppid1,ppid2..
Display only processes with the listed PPIDs.

-o User-defined format.

It is a single argument in the form of a blank-separated or comma-separated list, which offers a way
to specify individual output columns.

The argument to -o are following:

COL HEADER DESCRIPTION
─────────────────────────────────────────────────────────────────────────────────────────────────────
%cpu %CPU cpu utilization of the process
%mem %MEM physical memory on the machine expressed as a percentage
start START time the command started
time TIME accumulated cpu time, user + system
cls CLS scheduling class of the process.
cmd CMD see Task name. (alias args, command).
args COMMAND To display the full program name with its arguments (use at last position in -o
list to view full command)
pid PID The process ID
ppid PPID Parent process ID
pri PRI Priority of the process
state S see s
rss RSS the non-swapped physical memory that a task has used
rtprio RTPRIO real-time priority
pname Pname Process name
tty TT controlling tty (terminal)
uid UID see euid
uname USER see euser
vsize VSZ see vsz
wchan WCHAN name of the kernel function in which the process is sleeping

STANDARD FORMAT SPECIFIERS

Here are the different keywords that may be used to control the output format (e.g. with option -o) or to
sort the selected processes

For example: pcp-ps -o pid,user,args

CODE HEADER DESCRIPTION
──────────────────────────────────────────────────────────────────────────────────────────────────────────
pid PID a number representing the process ID
%cpu %CPU %cpu utilization of the process in "##.#" format.
Currently, it is the CPU time used divided by the time the process has been running
(cputime/realtime ratio), expressed as a percentage.
%mem %MEM %ratio of the process's resident set size to the physical memory on the machine,
expressed as a percentage.
args COMMAND Command with all its arguments as a string. Modifications to the arguments may be
shown. The output in this column may contain spaces. A process marked <defunct> is
partly dead, waiting to be fully destroyed by its parent. Sometimes the process args
will be unavailable; when this happens,will instead print the executable name in
brackets.
class CLS scheduling class of the process.
Field's 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
s S minimal state display. See also state if you want additional information displayed.
euid EUID effective user ID.
vsz VSZ virtual memory size of the process in KiB (1024-byte units). Device mappings are
currently excluded; this is subject to change.
euser EUSER effective user name. This will be the textual user ID, if it can be obtained and the
field width permits, or a decimal representation otherwise.
All N/A This option shows USER, PID, PPID, PRI, %CPU, %MEM, VSZ, RSS, S, START, TIME, WCHAN and
COMMAND.

-Z timezone, --timezone=timezone
By default, pcp-ps reports the time of day according to the local timezone on the system where
pcp-ps is run. The -Z option changes the timezone to timezone in the format of the environment
variable TZ as described in environ(7).

-z , --hostzone
Change the reporting timezone to the local timezone at the host that is the source of the
performance metrics. When replaying a PCP archive that was captured in a foreign timezone, the -z
option would almost always be used (the default reporting timezone is the local timezone, which
may not be the same as the timezone of the PCP archive).

-? , --help
Display usage message and exit.

NOTES

       pcp-ps is inspired by the ps(1) command and aims to be command line and output compatible with it.

PCP ENVIRONMENT

       Environment  variables with the prefix PCP_ are used to parameterize the file and directory names used by
       PCP.  On each installation, the file /etc/pcp.conf contains the local values for  these  variables.   The
       $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).

       For environment variables affecting PCP tools, see pmGetOptions(3).
