Consolidation metrics in a virtualization study

The Consolidation view and Optimizer simulate the allocation of a candidate onto a target. To correctly evaluate the effects of this allocation, the following resource metrics are required:

  • CPU-related metrics:
    • CPU_NUM
    • CPU_MHZ
    • CPU_UTIL (if available, CPU_UTILMHZ is preferred; otherwise, it is calculated via CPU_UTIL, CPU_NUM, CPU_MHZ)
    • CPU_ENTC_CONS (only for AIX consolidation)
  • Memory-related metrics:
    • MEM_UTIL
    • TOTAL_REAL_MEM
    • MEM_GRANTED or MEM_CONSUMED (for VMware consolidation and virtual machines only; obtained from log level 2 in VMware)
  • Bandwidth-related metrics:
    • NET_BIT_RATE
    • NET_BANDWIDTH
  • Disk-related metrics:
    • DISK_TRANSFER_RATE (optional)
    • DISK_MAX_TRANSFER_RATE (optional)

The following resource metrics can be (optionally) specified for compatibility tagging and checks:

  • OS_TYPE
  • OS_VER
  • CPU_MODEL
  • HW_MODEL
