vRealize Operations Manager uses different models for calculating available CPU, RAM and disk space.

You can configure vRealize Business for Cloud to synchronize with vRealize Operations Manager models for capacity calculations.

By using the update-config.py utility, you can modify the CPU, RAM and disk space properties according to the vRealize Operations Manager policies. For information about how to modify the values, see View and Update vRealize Business for Cloud Default Settings.

  • cpu.stats.model=alloc or cpu.stats.model=demand

  • memory.stats.model=alloc or memory.stats.model=demand or memory.stats.model=consumed

  • diskspace.stats.model=alloc or diskspace.stats.model=demand

By default, vRealize Business for Cloud uses the allocation and demand models to calculate available memory and to calculate the available CPU and disk capacity, vRealize Business for Cloud uses demand and consumption-based models.


Even when vRealize Business for Cloud contains multiple vCenter Server accounts that are monitored by different vRealize Operations Manager, all the vRealize Operations Manager instances use the same model. If you want to configure a specific vRealize Operations Manager instance with a different model, you must configure the respective vRealize Operations Manager instance.
