.SH NAME
|
||||||
|
ps_mem \- Memory profiling tool
|
||||||
|
.SH SYNOPSIS
|
||||||
|
.B ps_mem [OPTION]...
|
||||||
|
.SH DESCRIPTION
|
||||||
|
Display the core memory used per program (not per process)
|
||||||
|
.br
|
||||||
|
.PP
|
||||||
|
In detail it reports:
|
||||||
|
.br
|
||||||
|
.PP
|
||||||
|
.RS
|
||||||
|
sum (private RAM for program processes) +
|
||||||
|
.br
|
||||||
|
sum (shared RAM for program processes)
|
||||||
|
.br
|
||||||
|
.RE
|
||||||
|
.PP
|
||||||
|
The shared RAM is problematic to calculate, and the tool automatically selects the most accurate method available for the running kernel.

# Try to determine how much RAM is currently being used per program.

|
# Note per _program_, not per process. So for example this script
|

|
# will report RAM used by all httpd process together. In detail it reports:
|
||||||
|
# sum(private RAM for program processes) + sum(Shared RAM for program processes)
|

# The shared RAM is problematic to calculate, and this script automatically

|
# V1.0 06 Jul 2005 Initial release
|
||||||
|
# V1.1 11 Aug 2006 root permission required for accuracy
|
||||||
|
# V1.2 08 Nov 2006 Add total to output
|
||||||
|
# Use KiB,MiB,... for units rather than K,M,...
|
||||||
|
# V1.3 22 Nov 2006 Ignore shared col from /proc/$pid/statm for
|
||||||
|
# 2.6 kernels up to and including 2.6.9.
|
||||||
|
# There it represented the total file backed extent
|
||||||
|
# V1.4 23 Nov 2006 Remove total from output as it's meaningless
|
||||||
|
# (the shared values overlap with other programs).
|
||||||
|
# Display the shared column. This extra info is
|
||||||
|
# useful, especially as it overlaps between programs.
|
||||||
|
# V1.5 26 Mar 2007 Remove redundant recursion from human()
|
||||||
|
# V1.6 05 Jun 2007 Also report number of processes with a given name.
|
||||||
|
# Patch from riccardo.murri@gmail.com
|
||||||
|
# V1.7 20 Sep 2007 Use PSS from /proc/$pid/smaps if available, which
|
||||||
|
# fixes some over-estimation and allows totalling.
|
||||||
|
# Enumerate the PIDs directly rather than using ps,
|
||||||
|
# which fixes the possible race between reading
|
||||||
|
# RSS with ps, and shared memory with this program.
|
||||||
|
# Also we can show non truncated command names.
|
||||||
|
# V1.8 28 Sep 2007 More accurate matching for stats in /proc/$pid/smaps
|
||||||
|
# as otherwise could match libraries causing a crash.
|
||||||
|
# Patch from patrice.bouchand.fedora@gmail.com
|
||||||
|
# V1.9 20 Feb 2008 Fix invalid values reported when PSS is available.
|
||||||
|
# Reported by Andrey Borzenkov <arvidjaar@mail.ru>
|
||||||
|
# V3.14 28 May 2022
|
||||||
|
# https://github.com/pixelb/ps_mem/commits/master/ps_mem.py
|
||||||
|
|
||||||
|
# Notes:
|
||||||
|
#
|
||||||
|
# All interpreted programs where the interpreter is started
|
||||||
|
# by the shell or with env, will be merged to the interpreter
|
||||||
|
# (as that's what's given to exec). For e.g. all python programs
|
||||||
|
# starting with "#!/usr/bin/env python" will be grouped under python.
|
||||||
|
# You can change this by using the full command line but that will
|
||||||
|
# have the undesirable affect of splitting up programs started with
|
||||||
|
# differing parameters (for e.g. mingetty tty[1-6]).
|
||||||
|
#
|
||||||
|
# For 2.6 kernels up to and including 2.6.13 and later 2.4 redhat kernels
|
||||||
|
# (rmap vm without smaps) it can not be accurately determined how many pages
|
||||||
|
# are shared between processes in general or within a program in our case:
|
||||||
|
# http://lkml.org/lkml/2005/7/6/250
|
||||||
|
# A warning is printed if overestimation is possible.
|
||||||
|
# In addition for 2.6 kernels up to 2.6.9 inclusive, the shared
|
||||||
|
# value in /proc/$pid/statm is the total file-backed extent of a process.
|
||||||
|
# We ignore that, introducing more overestimation, again printing a warning.
|
||||||
|
# Since kernel 2.6.23-rc8-mm1 PSS is available in smaps, which allows
|
||||||
|
# us to calculate a more accurate value for the total RAM used by programs.
|
||||||
|
#
|
||||||
|
# Programs that use CLONE_VM without CLONE_THREAD are discounted by assuming
|
||||||
|
# they're the only programs that have the same /proc/$PID/smaps file for
|
||||||
|
# each instance. This will fail if there are multiple real instances of a
|
||||||
|
# program that then use CLONE_VM without CLONE_THREAD, or if a clone changes
|
||||||
|
# its memory map while we're checksumming each /proc/$PID/smaps.
|
||||||
|
#
|
||||||
|
# I don't take account of memory allocated for a program
|
||||||
|
# by other programs. For e.g. memory used in the X server for
|
||||||
|
# a program could be determined, but is not.
|
||||||

#

# FreeBSD is supported if linprocfs is mounted at /compat/linux/proc/

%description
|
||||||
|
The ps_mem tool reports how much core memory is used per program
|
||||||
|
(not per process). In detail it reports:
|
||||||
|
sum(private RAM for program processes) + sum(Shared RAM for program processes)
|
||||||
|
The shared RAM is problematic to calculate, and the tool automatically
|
||||||
|
selects the most accurate method available for the running kernel.
