Measures reported by LparinfoTest

This test auto-discovers the LPARs on a pSeries server, reports the amount of CPU and memory resources that each LPAR is configured with, reveals the extent of usage of the allocated resources by every LPAR, and also updates you with the powered-on status of these LPARs. Using the measures reported by this test, the following can be quickly ascertained:

  • Which LPAR is currently powered-off?
  • Which LPAR is utilizing virtual CPU and virtual memory optimally? Are there any resource-hungry LPARs? If so, which ones are they?
  • Is any LPAR under-sized/over-sized in terms of the CPU and memory allocated to it? If so, which one is it?
  • What is the maximum limit to which the processing capacity of an LPAR can be allowed to grow?
  • What is the processing capacity configuration of every LPAR's shared resource pool?
Measurement Description Measurement Unit Interpretation
PoweredOn Whether this LPAR is powered on or not   If this measure returns the value 'Yes', it indicates that the LPAR is powered-on. The value 'No' on the other hand indicates that the LPAR is powered off. The table below displays the values that can be reported by this measure, and their numeric equivalents:
Measure Value Numeric Equivalent
Yes 0
No 1

Note:

By default, this measure reports one of the Measure Values listed in the table above. The graph of this measure however will represent the VM status using the numeric equivalents - 0 or 1.

Virtualcpu The number of virtual CPUs currently being used by this LPAR Number A high value of this measure indicates excessive CPU usage by an LPAR. Comparing the value of this measure across LPARs will enable you to quickly and accurately point to that LPAR that is consuming too much CPU. To know whether the CPU resources of this LPAR are capped or uncapped, use the detailed diagnosis of this measure. This will additionally reveal the partition ID and type (whether dedicated or shared) as well.
Maxvirtualcpu The maximum number of virtual CPUs that can be utilized by this LPAR Number  
Minvirtualcpu The minimum number of virtual CPUs configured for this LPAR Number  
OnlineMem The amount of allocated memory resources currently utilized by this LPAR MB A high value of this measure indicates excessive memory usage by an LPAR. Comparing the value of this measure across LPARs will enable you to quickly and accurately point to that LPAR that is consuming too much memory.
MaxMem The maximum amount of memory that this LPAR can use MB  
MinMem The minimum amount of memory allocated to this LPAR MB  
CapacityInc The minimum capacity (in units of 1/100 of a physical processor) that can be added to or removed from this partition's processor capacity Number This measure indicates the granule at which changes to Entitled Capacity can be made. A value in whole multiples indicates a Dedicated LPAR.
Maxcapacity The maximum number of processing units that this LPAR can use Number The entitled capacity of the LPAR can go up to the value of this measure.
Mincapacity The minimum number of processing units required by this LPAR for its functioning Number The entitled capacity of the LPAR cannot go down beyond the value of this measure.
ActivePhyCpu The current number of active physical CPUs in the system containing this LPAR Number  
MaxPhyCpu The maximum number of physical CPUs that can be used by this LPAR Number  
ActiveCpuPool The maximum number of CPUs available to this LPAR's shared processor pool Number  
ShredPhyCpu The number of physical CPUs available for use by shared processor LPARs Number  
EntilPoolCapacity The number of processing units that this LPAR's shared processor pool is entitled to receive Number  
MaxPoolCapacity The maximum number of processing units available to this LPAR's shared processor pool Processing units  
UnallocateCpacity The sum of the number of processor units unallocated from shared LPARs in an LPAR group Processing units This sum does not include the processor units unallocated from a dedicated LPAR, which can also belong to the group. The unallocated processor units can be allocated to any dedicated LPAR (if it is greater than or equal to 1.0 ) or shared LPAR of the group.
UnallocateWeight The number of variable processor capacity weight units currently unallocated within the LPAR group Processing units
