Sure, there you go (nmon comes these days as part of AIX - same as topaz or replaced it):
Code :
notroot@somehost:/home/notroot# nmon -v
nmon version TOPAS-NMON build AIX
notroot@somehost:/home/notroot# oslevel -s
6100-06-05-1115
notroot@somehost:/home/notroot# which nmon
/usr/bin/nmon
notroot@somehost:/home/notroot# lslpp -w /usr/bin/nmon
File Fileset Type
----------------------------------------------------------------------------
/usr/bin/nmon bos.perf.tools File
notroot@somehost:/home/notroot# nmon -h
Hint: topas_nmon [-h] [-s <seconds>] [-c <count>] [-f -d -t -r <name>] [-x]
Command: TOPAS_NMON
-h FULL help information - much more than here
Interactive-Mode:
read startup banner and type: "h" once it is running
For Data-Collect-Mode (-f)
-f spreadsheet output format [note: default -s300 -c288]
optional
-s <seconds> between refreshing the screen [default 2]
-c <number> of refreshes [default millions]
-t spreadsheet includes top processes
-x capacity planning (15 min for 1 day = -fdt -s 900 -c 96)
For Interactive-Mode
-s <seconds> between refreshing the screen [default 2]
-c <number> of refreshes [default millions]
-g <filename> User decided Disk Groups
- file = on each line: group_name <hdisk_list> space separated
- like: rootvg hdisk0 hdisk1 hdisk2
- upto 32 groups hdisks can appear more than once
-b black and white [default is colour]
-B no boxes [default is show boxes]
example: topas_nmon -s 1 -c 100
For Data-Collect-Mode = spreadsheet format (comma separated values)
Note: use only one of f,F,z,x or X and make it the first argument
-f spreadsheet output format [note: default -s300 -c288]
output file is <hostname>_YYYYMMDD_HHMM.nmon
-F <filename> same as -f but user supplied filename
-r <runname> goes into spreadsheet file [default hostname]
-t include top processes in the output
-T as -t plus saves command line arguments in UARG section
-Y like -t but all commands with the same name are added up and reported
Note: you can have only one of -t, -T or -Y (last on the cmd line wins)
-s <seconds> between snap shots
-c <number> of refreshes
-w <number> Timestamp size (Tnnnn), values4 to 16, for analyser use 4 or 8
-l <dpl> disks/line default 150 to avoid spreadsheet issues. For EMC use 64
-g <filename> User decided Disk Groups (see above -g)
-d Include Disk Service time sections
-k <disklist> Only report these disks also works online (Example -k hdisk3,hdisk23,hdisk44)
-G Use UTC/GMT standard time (not local time)
-K Include RAW Kernel & LPAR sections (RAWLPAR & RAWCPUTOTAL)
-D Skip disk configuration sections
-E Skip ESS configuration sections
-J Skip JFS sections
-V Include disk Volume Group section
-P Include Paging Space section
-M Include MEMPAGES section = detailed memory stats per page size
-N Include NFS section, use -NN for NFSv4 stats.
-W Include WLM sections
-S Include WLM sections with SubClasses
-^ Include Fibre Channel (FC) sections
-O Include Shared Ethernet Adpater (SEA) VIOS only sections
-L Include LARGE page section
-I <percent> Ignore process percent threshold (default 0.1)
don't save TOP stats if proc using less CPU than this %
-A Include Async I/O Section
-m <dir> nmon changes to this directory before saving data to a file
-Z <priority> set nice priority -20=important to 20=unimportant (negative only for root user)
example: collect for 1 hour at 30 second intervals with top procs
topas_nmon -f -t -r Test1 -s30 -c120
To load into a spreadsheet like Lotus 1-2-3:
sort -A *nmon >stats.csv
transfer the stats.csv file to your PC
Start 1-2-3 and then Open <char-separated-value ASCII file>
Capacity planning mode - use cron to run each day
-x sensible spreadsheet output for CP = one day
every 15 mins for 1 day ( i.e. -ft -s 900 -c 96)
-X sensible spreadsheet output for CP = busy hour
every 30 secs for 1 hour ( i.e. -ft -s 30 -c 120)
Set-up and installation
To enable disk stats as root: chdev -l sys0 -a iostat=true
- this adds the disk % busy numbers (otherwise they are zero)
If you have hundreds of disk this can take 1% to 2% CPU
Interactive Mode Commands
key --- Toggles to control what is displayed ---
h = Online help information
r = Resources pSeries type, machine name, cache details and AIX version + LPAR
p = Partitions stats
c = CPU by processor stats with bar graphs
#=toggle PURR based stats (POWER5/6 shared CPUs only)
C = CPU by processor stats for high numbers of CPU
l = long term CPU (over 75 snapshots) with bar graphs
m = Memory and Paging stats
M = Multiple Page Size stats in pages - 2nd time in MB's
k = Kernel Internal stats
n = Network stats
= = For Network & Disk Toggle KB/s to MB/s
O = Shared Ethernet Adapter VIOS only
N = NFS Network File System stats (2nd N gets you NFSv4)
d = Disk I/O Graphs (see -k to limit to specific disks)
D = Disk I/O Stats - multiple times gets you more stats
o = Disk I/O Map (one character per disk showing how busy it is)
g = Disk Group I/O Stats (have to use -g commandline option)
a = Adapter I/O Stats
^ = Fibre Channel Adapter via fcstat command
[ = Start an On demand nmon recording
] = Stop an On demand nmon recording
e = ESS vpath Logical Disk I/O Stats
V = Disk Volume Group stats
P = Paging Space stats
j = JFS Stats
t = Top Process Stats 1=Basic-Details 2=Accumulated-CPU
Performance sorted by 3=CPU 4=Size 5=I/O
u = Top but with command arguments shown (used with 3,4 & 5)
to refresh arguments (for new processes) hit u twice
U = as u plus Workload Classes/WPAR
W = Workload Management (WLM) Stats
S = WLM with SubClasses
w = use with top to show AIX wait processes (good for SMP)
A = Summarise Async I/O (aioserver) processes
v = Verbose this highlights problems on the machine and
categorises them as either danger, warnings or OK
b = black and white mode (or use -b option)
. = minimum mode i.e. only busy disks and processes
~ = switch to topas screen
key --- Other Controls ---
+ = double the screen refresh time
- = halves the screen refresh time
q = quit (also x)
0 = reset peak counts to zero (peak = ">")
space = refresh screen now
Startup Control
If you find you always type the same toggles every time you start
then place them in the NMON shell variable. For example:
export NMON=cmdrvtan
Others:
a) Do you want to stop nmon - kill -USR2 <nmon-pid>
b) Use -p and nmon outputs the background process pid
c) To limit the processes nmon lists (online and to a file)
Either set NMONCMD0 to NMONCMD63 to the program names
or use -C cmd:cmd:cmd etc. example: -C ksh:vi:syncd
d) To limit the disks nmon lists up to 64 (online only)
Use -k diskname,diskname,diskname (Example -k hdisk2,hdisk0,hdisk3)
As said, even in other combinations of switches etc., like without -C etc. there was not the output I expected.
