#================================================================================
#  Mundane Performance Data Collection script

#  Please execute as root-user using syntax not unlike:
#  /bin/ksh ./AIX_Perf_Monitor.ksh
#  Please send a compressed collection report to Earl, earlj@us.ibm.com
#  and I will review and offer my findings by telephone/conf call.

#  Please execute this script when there is an active workload of concern.
#  The script below collects 500kb-20mb of textdata per run.
#================================================================================

#================================================================================
#  Stephen Diwell - Version 2.0
#                 - Added some code to avoid running root only commands (hpmstat/vmo/ioo etc)
#                   if a normal non-root user executes the script.  if [[ ${IAM} == 'root' ]]
#                 - Fixed the awk statement in the lsdev line for entstat and fcstat commands.
#                   I removed the \ and grep statement and added the search string to awk.
#                 - Fixed the lsvg command to lsvg -o so script only queries varyied on VGs.
#                 - Added the -n flag to netstat commands to avoid DNS resolution pauses.
#
#  Stephen Diwell - Version 3.0
#                 - This script now creates its own unique logfile and
#                   re-directs all output to this file and the screen.
#                 - Added the -e and -h flag options.
#                   If you run as root, it will only run the hpmstat command
#                   if you add the -e flag.  The -h is for basic help.
#                 - Added extra ps -fe | sort -nk4 to show most recent active processes.
#                 - Added iostat -F to show most active file systems for IO
#                 - Added some INFORMATION heading, more will be added in next release.
#
#  Stephen Diwell - Version 3.1
#                 - Added hostname to output filename.
#
#  Stephen Diwell - Version 3.2
#                 - Added ps avx - processes and memory size output.
#                 - Added lsvg -l ${VG}
#                 - Added lsattr output for disk attributes.
#                 - Added lslv -l ${LV} output - show disks LV is on.
#                 - Added lsuser -a id pgrp  ALL - For corrolation of stats to user.
#
#  Stephen Diwell - Version 3.3
#                 - Added lsattr for Ethernet and Fibre adapters.
#
#  Stephen Diwell - Version 3.4 - June 2017
#                 - Removed the lsuser output at Earl's request.
#                 - Added the pmcycles -d output.
#  
#  Patrice Quet   - Version 3.5 - March 2018
#                 - Adding ps -kfZ and ps -efZ to display page sizes used by processes.
#
#  Patrice Quet   - Version 3.6 - June 2018
#                 - Adding KDB mempool subcommand to show mempsum free frames
#
#  Patrice Quet   - Version 3.7 - July 2018
#                 - Adding vmstat -IP all to display number of used and free frames of different sizes.
#
#  Patrice Quet   - Version 3.8 - November 2018
#                 - Added option to svmon -G command to display affinity domains related to memory
#                 - Added mpstat -a into cumulative mpstat statistics
#
# Chris Gibson    - Version 3.9 - February 2019
#	          - Added -E option to lparstat to display processor clock frequency.
#
#  Patrice Quet   - Version 3.10 - March 2019
#		  - Added MPIO cumulative and real-time statistics with iostat -m
#
#  Stephen Diwell - Version 3.11 - May 2019 - Added mpstat -v for > AIX 7.1 TL3 SP2
#
#  Phil Langerholc - Version 3.13 - November 2019 - added mmdf for GPFS installations to check the data in the
#                                                   file system is balanced
