Performance dashboard

Starting with HMC Version 10.3.1050, or later, you can view the Performance dashboard by accessing it from the navigation area. The Performance dashboard displays the allocation and usage data for virtualized server resources. It displays data in the form of charts, graphs, and tables.

The Performance dashboard gathers data and provides capacity reporting and performance monitoring information. This information can help you to determine the available capacity of the selected system and whether your resources might be overextended or underused. In addition, the graphs and tables are useful for capacity planning and troubleshooting. For more information about Performance dashboard, see Using the Performance and Capacity Monitor.

The Performance dashboard captures data only from the systems for which you choose to enable data collection.
