Planning the Capacity for Your Managed Environment Using vRealize Operations Manager 2 You can use the Projects feature in vRealize Operations Manager to plan for capacity allocations and upgrades in your virtual environment, or to optimize your existing resources. To plan your upcoming capacity needs, you create a project that anticipates forthcoming changes that affect the capacity of your objects.
vRealize Operations Manager User Guide When you create a project, you add one or more capacity scenarios to the project to determine your future needs. Project scenarios anticipate the changes to capacity or demand that affect the object at an upcoming time and date. After you save each project, you drag the project to the visualization pane to chart the capacity forecast. You can see the anticipated capacity needs in the chart based on the values that you defined in your project scenarios.
Chapter 2 Planning the Capacity for Your Managed Environment Using vRealize Operations Manager Project Scenarios Model Changes to Resources You can use the following project scenarios to forecast capacity. Table 2‑1. Project Scenarios for Selected Objects Selected Object Project Scenarios vCenter Server Capacity n Add or remove host system, datastore, or percentage of capacity. n Change absolute capacity. Demand n Add or remove virtual machine or percentage of demand. n Change absolute demand.
vRealize Operations Manager User Guide In vRealize Operations Manager, stress involves how high and how long the demand persists relative to the capacity available, and vRealize Operations Manager uses this value to measure the potential for performance problems. The higher the stress score, the worse the potential is for degraded performance on your objects. Depending on the configuration of the policy analysis settings for stress, a score of green might indicate 0–24 percent of stress.
Chapter 2 Planning the Capacity for Your Managed Environment Using vRealize Operations Manager To modify the stress score thresholds, edit the policy that applies to your objects, and click Analysis Settings. Select an object type and click the filter icon to display the policy analysis settings. In the Stress area, click the lock icon, expand Stress, and modify the stress thresholds.
