  1. Nigel Griffiths • Advanced Technical Support • IBM Europe Topas and nmon

  2. nmon for Linux now Open Source • nmon for Linux on Power then added x86, Z, x86_64 • Released by IBM - July 2009 • http://nmon.sourceforge.net • Compile for your Linux flavour • Cell blades, disk engines, • Diskless, embedded ++ • On a Linux Distro's !!

  3. nmon for AIX4 … add AIX5 & AIX6 … nmon 12e for AIX … nmon function within topas • AIX 5.3 TL09 - TL11, + • AIX 6.1 TL02 - TL04, + October 2008

  28. nmon is half the story The other half is due to the nmon Analyser & nmon Consolidator Excel spreadsheets from Stephen Atkins, UK another personal time project

  29. nmon Consolidator v1.4.1 • Produces overview charts for CPU, Memory, Network, Disk • Fast & simple code, pre-generated charts • Multiple nmon/topasout files for: • ALL LPARs of one machine • Clustered system – Oracle RAC / HPC • Modelling changes from Dedicated to Shared CPU LPARs • Server consolidation Modelling • Reporting actual or potential savings from virtualisation • Trend charts - processing multiple files from 1 LPAR

  30. AIX Labs in 2008: “nmon will be assimilated!”

  31. Code stuffing Lines of code from 6500  9000

  32. Advanced, POWER6 and AIX6 items • Virtual I/O Server SEA via entstat • Partition Mobility (POWER6) • WPAR & Application Mobility (AIX6) • Dedicated Donating (POWER6) • Folded CPU count (SPLPAR) • Multiple Shared Pools (POWER6) • Fibre Channel stats via fcstat nmon on POWER6 & AIX6 + New Features for V12 User Requested • Disk Service Times • Selecting Particular Disks • Time Drift • Multiple Page Sizes 4KB, 64KB, ++ • Timestamps in UTC & no. of digits • More Kernel & Hypervisor Stats * • High Priority nmon Housekeeping items • Bug fixes – small or fine tuning, see nmon wiki for a list • Network packet sizes now saved to file • Warnings from nmon like: network overflow • TOP Online - sizes in KB, MB, GB to keep columns aligned • Fast abort in capture mode – SIGUSR1 during config collection stops nmon • Return an error & on invalid options – return codes to check it finished normally • Adapter "not available" work around – see nmon FAQ wiki about these AIX bugs • EMC hdiskpower renamed to “power” to save screen space • NFS v4 for AIX 5.3 ML5+
