CPU overview and Memory overview charts
In the Ignite management console, you can view two donut charts at the top of the Migration Zone Overview page that show the following:
- CPU Overview - Displays the Total CPU in the migration zone (that is, the sum of CPU provided by all nodes assigned to the migration zone). This total is broken down into Unallocated CPU and CPU that has been Allocated to virtual datacenters. The Load represents the average CPU utilization across all nodes in the migration zone, including hypervisor usage. This utilization is calculated as a percentage of the total allocated CPU. At the bottom of the donut chart, Ignite displays the migration zone's Oversubscription as a percentage of the Total CPU. A value over 100% indicates that the migration zone is oversubscribed.
- Memory Overview - Displays the Total Memory in the migration zone (that is, the sum of all memory provided by all nodes assigned to the migration zone). This total is broken down into Unallocated memory and memory that has been Allocated to virtual datacenters. Allocated memory is further divided into memory In Use by application instances and Free memory; free memory is memory that has been allocated to virtual datacenters, but is not currently in use by applications.
Migration zone activity charts
- On the Migration Zone Activity tab, you can view two charts showing recent activity in the migration zone. You can adjust the time interval displayed in the charts between the last hour and the last year.
