Stress removed in vRealize Operations Manager 6.7 and later

Products

• VMware Aria Suite

Issue/Introduction

Symptoms:

• Stress metrics and settings are missing.

Environment

VMware vRealize Operations Manager 7.0.x
VMware vRealize Operations Manager 6.7.x

Cause

In prior releases of vRealize Operations Manager, historical capacity utilization crossing a user-specified “stress” line was used to calculate Capacity Remaining, Time Remaining, and Recommended Size metrics.
However, with the new forecast-based capacity analytics in 6.7, the concept of recent utilization “stress” has been removed.

Resolution

In vRealize Operations Manager 6.7 and later, Capacity Remaining, Time Remaining, and Recommended Size metrics are now calculated based on predicted demand utilization against usable capacity.

In the old capacity model the recommended capacity is the capacity that is required to avoid stress, which has been computed based on the recent past period.

The new forecast-based capacity model computes the number of days remaining after which the usable capacity is no longer enough to support projected utilization.
The recommended capacity is the capacity needed to keep Time Remaining green based on policy settings.
