Use the troubleshooting features of vRealize Operations Manager to examine problems that put your objects in a critical state, and identify solutions. To resolve the resource and time remaining problems, use the Capacity Optimization function.
You have used the Alerts, Details, All Metrics, and Environment areas of the user interface to examine critical problems such as resource contention and time remaining issues that occur on your objects. To resolve those problems, you can use the Capacity Optimization function.
Examine the environment relationships. See Examine the Environment Relationships.
- In the menu, click Home, then click Overview under Optimize Capacity in the left pane. The Capacity Overview screen appears.
- Select the data center - DC-Denver-19 - that contains the problem objects.
The data in the lower half of the screen refreshes to display time remaining information and reclaim recommendations for selected data center DC-Chicago-12. NOTE: Double-clicking the data center graphic displays the Object Details page for that data center.
- At the graph, select Most Constrained from the Sort By: choices and CPU from CPU|Memory|Disk Space above the graph.
The graph refreshes to show the usage value almost touching 100% and the timeline/projection value nearly intersecting the usage value. The data center is almost out of CPU.
- Scroll down the page to the Recommendations below the graph.
Option 1 lists total resources (CPU, memory, disk space) that can be reclaimed. Option 2 lists the hardware to purchase to increase time remaining to 150 days.
- Click RECLAIM RESOURCES.
The Reclaim screen appears, displaying data for DC-Chicago-12. The "How much can you save?" pane shows that $4140/month can potentially be saved. Looking to the top of the table, you see that the $4140 sum appears next to Oversized VMs.
- Click Oversized VMs. Then click the chevron next to a cluster name on the left of the table.
All the VMs in the cluster are listed.
- Select the check box next to VM Name in the table heading.
All the VMs in the cluster are checked.
- Click RESIZE VM(s).
The Resize VMs page appears, showing the 20 VMs available for resizing.
- Leave the recommendation as is, without editing the target reductions, then select the "I understand that workloads may be interrupted..." check box and click RESIZE VM(s).
The system runs the resize action.
You have used Capacity Optimization to resolve problems on a host system that is experiencing critical problems. The data center does not run out of CPU, and instead realizes projected cost savings of nearly $50,000 annually.
What to do next
To become aware of critical problems on your objects before they adversely affect the performance of other objects and your environment, configure the Workload Optimization alerts to be automated. See the vRealize Operations Manager Configuration Guide.
