# All credit goes to Brendan, here is why:

# Thanks to Brendan Gregg on his website he has this (he invented this): http://www.brendangregg.com/ColonyGraphs/cloud.html
I just rewrote it so that I can remember it and study it. Also I have added some added variations so that linux users can play around as well (very simple ps line). Anyhow this persons the system performance linux/unix God, so i trust this as a great method to get a snapshot of processes. You can use this process to get a pic of every process on your server/rack/datacenter.

# / startrant
# Brendan Greggs work is something every linux/unix geek/nerd should look into. Brendan if you see this, thank you! I want to read your Biography if you have one (its prob on your site, havent looked deep enough yet - nvm... just noticed it on your site). But I want to know how you started learning all this so that I can follow in your footsteps! Also please give me the code on how to make the gif versions that utilizes the "present" variable so i can make visualized models. Im positive this will help everyone! Infact I think I will send you an email on this topic.

# Here is his site: http://www.brendangregg.com/ColonyGraphs/cloud.html

# Your about to embark on making this

apt-get install graphviz
apt-get install awk

# wget the files necessary for this from brendan greggs site:
wget http://www.brendangregg.com/ColonyGraphs/ps2gv-p.sh
wget http://www.brendangregg.com/ColonyGraphs/colors.awk
# if links down - source code of those files below

# since linux and mac dont really use zone files, we manually add them in

# in linux:
ps -o ppid,pid,rss,pcpu,comm x | awk '{ print "-", $0 }' > ps.txt

# in mac:
ps -eo ppid,pid,rss,pcpu,comm | awk '{ print "-", $0 }' > ps.txt

# in solaris:
ps -eo zone,ppid,pid,rss,pcpu,comm > ps.txt

# basically if your sys doesnt support zones, then your ps output should be like this (not including awk):

PPID PID RSS %CPU COMMAND
0 1 3772 0.0 systemd
0 2 0 0.0 kthreadd
2 3 0 0.0 ksoftirqd/0
2 6 0 0.0 migration/0
2 7 0 0.0 watchdog/0
2 8 0 0.0 migration/1

# after the awk command the final txt file should look like this (this is the ps and awk):

- PPID PID RSS %CPU COMMAND
- 0 1 3768 0.0 systemd
- 0 2 0 0.0 kthreadd
- 2 3 0 0.0 ksoftirqd/0
- 2 6 0 0.0 migration/0
- 2 7 0 0.0 watchdog/0
- 2 8 0 0.0 migration/1

# and if it does support zones, it should be like this:

ZONE PPID PID RSS %CPU COMMAND
global 0 0 0 0.0 sched
global 0 1 1284 0.0 /sbin/init
global 0 2 0 0.0 pageout
global 0 3 0 0.1 fsflush
global 1 159 1672 0.0 /usr/lib/power/powerd
global 1 39 19560 0.0 /lib/svc/bin/svc.startd

# generate .gv file (an ascii file with dot info)
./ps2gv-p.sh ps.txt

# note if had several "ps.txts" you can combine them like this ./

# generate pictures
neato -Tpng -Nfontsize=12 -Elen=1.9 ps.gv -o ps.png

# NOTE FROM DEV:
# Adjust -Nfontsize and -Elen (edge length) as desired. You can also customize the colors.awk file, which maps process names to colors. It uses gray if a mapping isn't present. There is also setting in ps2gv-p.sh, cpulimit, which adjusts the scaling of the node sizes.

# ps2gv-p.sh #

#!/bin/sh
#
# ps2gv-p.sh ptree info to graphvis, with present column.
#
# USAGE: ps2gv-p.sh ptree1.txt [...]
#
# Converts provided ptree input files to .gv files. The input file has the
# following format (space or tab delimitered):
#
# zonename ppid pid rss pcpu comm [present=1]
#
# Which can be generated using "ps -eo zone,ppid,pid,rss,pcpu,comm".
# If your OS does not have the zone field, then add a dummy field using awk,
# or edit this script to drop it. The final optional column, present, can be
# post-generated using perl, and is used for animated sequences.
#
# See: http://www.brendangregg.com/ColonyGraphs/cloud.html

hidezone=1 # convert zonenames to "zone-000n"
cpulimit=10 # scale node size from 0 to cpulimit percent

# For an OS where a single busy process shows pcpu as 100%, such as Linux,
# cpulimit can be set to 100. You may want to use smaller values, eg, 10, to
# emphasize smaller CPU consumers. For OSes where pcpu is the average across
# all CPUs, eg, Solaris, you will want to make cpulimit much smaller (divide
# by number of CPUs).
