Free performance monitoring and capacity planning for IBM Power Systems™

CPU pool in LPAR2RRD
LPAR2RRD generates historical, future trends and nearly "real-time" CPU utilization graphs of LPAR's and shared CPU usage of IBM Power Systems™ servers.
It is agent less (it gets everything from the HMC/SDMC/FSM or IVM).
It supports all kinds of logical partitions: AIX®, IBM i® (i5/OS®), Linux®, VIOS.
It collects complete physical and logical configuration of all servers and LPAR's.

For customers under support there is distributed a full version with additional benefits.

Announcements in brief

Why use LPAR2RRD?

  • 1st of all due to its unique web based GUI for graphical interpretation of physical CPU utilization in virtualized environment. You can on a click find total CPU utilization of any physical box in a simple graphical form understandable from technician to management level
  • it is free for use, you do not need to invest into expensive commercial solutions. You can optionally buy support.
  • it is agent less == there is no any administration need if there is ANY change in your virtual environment
  • it does not require ANY administration, you just put there SDMC/HMC/IVM/FLEX names, allow ssh access there and that's it!
    in comparsion to other commercial tools where you need to have dedicated and trained staff for administration of them
  • you can on a click export internally stored data in CVS format for further analysis via 3rd party tools

How it works

system diagram LPAR2RRD


  • it is able to graph Active Memory Sharing usage
  • CPU Workload Estimator brings possibility to estimate before any LPAR migration if the target HW is cope with CPU load of migrated LPAR(s)
    It has option to make estimations and graphs based on rPerf or CPW benchmarks rather than on CPU cores. This allows you to get realistic view when you migrate a LPAR between different IBM Power™ servers.
  • You are allowed to group LPARs or CPU pools from different servers into Custom Groups what gives you easy overview of CPU load per the OS clusters, aplication layers etc ...
  • It is able to raise an alerts if CPU exceeds defined threshold for a LPAR or CPU pool
  • Live Partition Mobility and generally LPAR migration support
  • it is able to graph CPU usage prediction 1 year ahead yearly trend graphs
  • it is no longer only an off-line tool. You can do refresh (via a WEB link) whenever you want to get nearly "real-time" graphs
  • agent-less, no agents need to be installed on LPAR's. It gets all data from HMC/SDMC/IVM/FLEX servers
  • support of all types of LPAR's and OS'es : AIX®, VIOS, IBM i® (i5/OS®), Linux® on IBM Power™ Systems
  • It collects "Physical and Logical configuration" : Summary and Detail examples
  • it graphs LAN traffic of all IVE/HEA adapters and SAN traffic (available only for IVM based servers)
  • simple to install, configure and use
    initial install & configuration together with dependency tools should not take more than an hour!
  • no additional management required when you change/add/remove/rename a LPAR or managed system/frame (the tool discovers everything automatically for all already configured HMC/SDMC/IVM/FLEX)
  • data CSV outputs for processing by other tools, include output of server's configuration
  • it can be hosted on any *NIX platform, it needs a web server, SSH, Perl and RRDTool installed.
  • this is not replacement of tools like IBM Tivoli, Ganglia or Nagios which monitor everything (CPU/MEM/IO/LAN...), it is rather an add-on tool for physical CPU monitoring of IBM Power™ platform which we hope does that particular thing better than the others. Typical usage is for capacity planning purposes, although it is possible to use it also in "real-time" mode.
  • it should act as the tool which easy identifies CPU load abnormality and locates it up to the LPAR level. For further deeper analysis is necessary to use AIX® OS tools like nmon, topas, trace ...
  • it is not a tool for partitions using dedicated CPUs, it always shows 100% CPU utilization for them (unfortunately HMC/IVM/SDMC/FLEX do not provide detailed CPU stats usage for LPARs with dedicated CPU)
  • it does not have a perfect WEB front-end, no nice menus ... functionality and simplicity is primary target.

Next major areas we are going to focus are:
  • VMware porting is still open.
    Feel free to let us know if that is something what you wish to have in the product via
  • Brand new GUI (Q2 2014)
  • Authentication and authorization will come together with the new GUI
    (you will be able to define what information will be provided for everyone)
  • Support of WPARS via the OS agent (Q2 2014)
  • HMC monitoring itself: CPU, Memory, Paging (Q2 2014)
  • OS agent data export into CSV
  • Custom Groups CPU graphs based on rPerf benchmark
  • Custom Groups enhanced about OS agent data
