使い方
コマンドラインオプション
Hint: nmon [-h] [-s <seconds>] [-c <count>] [-f -d <disks> -t -r <name>] [-x] -h FULL help information 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] -d <disks> to increase the number of disks [default 256] -t spreadsheet includes top processes -x capacity planning (15 min for 1 day = -fdt -s 900 -c 96) Version - nmon 14g For Interactive-Mode -s <seconds> time between refreshing the screen [default 2] -c <number> of refreshes [default millions] -g <filename> User Defined Disk Groups [hit g to show them] - file = on each line: group_name <disks list> space separated - like: database sdb sdc sdd sde - upto 64 disk groups, 512 disks per line - disks can appear more than once and in many groups -b black and white [default is colour] example: 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> used in the spreadsheet file [default hostname] -t include top processes in the output -T as -t plus saves command line arguments in UARG section -s <seconds> between snap shots -c <number> of snapshots before nmon stops -d <disks> to increase the number of disks [default 256] -l <dpl> disks/line default 150 to avoid spreadsheet issues. EMC=64. -g <filename> User Defined Disk Groups (see above) - see BBBG & DG lines -N include NFS Network File System -I <percent> Include process & disks busy threshold (default 0.1) don't save or show proc/disk using less than this percent -m <directory> nmon changes to this directory before saving to file example: collect for 1 hour at 30 second intervals with top procs nmon -f -t -r Test1 -s30 -c120 To load into a spreadsheet: sort -A *nmon >stats.csv transfer the stats.csv file to your PC Start spreadsheet & then Open type=comma-separated-value ASCII file The nmon analyser or consolidator does not need the file sorted. 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) Interactive Mode Commands key --- Toggles to control what is displayed --- h = Online help information r = Machine type, machine name, cache details and OS version + LPAR c = CPU by processor stats with bar graphs l = long term CPU (over 75 snapshots) with bar graphs m = Memory stats L = Huge memory page stats V = Virtual Memory and Swap stats k = Kernel Internal stats n = Network stats and errors N = NFS Network File System d = Disk I/O Graphs D = Disk I/O Stats o = Disk I/O Map (one character per disk showing how busy it is) o = User Defined Disk Groups j = File Systems t = Top Process stats use 1,3,4,5 to select the data & order u = Top Process full command details v = Verbose mode - tries to make recommendations b = black and white mode (or use -b option) . = minimum mode i.e. only busy disks and processes key --- Other Controls --- + = double the screen refresh time - = halves the screen refresh time q = quit (also x, e or control-C) 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) To 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) If you want to pipe nmon output to other commands use a FIFO: mkfifo /tmp/mypipe nmon -F /tmp/mypipe & grep /tmp/mypipe e) If nmon fails please report it with: 1) nmon version like: 14g 2) the output of cat /proc/cpuinfo 3) some clue of what you were doing 4) I may ask you to run the debug version Developer Nigel Griffiths Feedback welcome - on the current release only and state exactly the problem No warranty given or implied.
