Additional features

Planning for virtual machine migrations

The VMware Modeler dashboard provides a mechanism you can use to view the impact that migrating a virtual machine will have on a target ESX Host. This dashboard takes up the entire display area of the Foglight for VMware browser interface. It can be accessed in two different ways:

•
If you are in the VMware Explorer dashboard, you can access the VMware Modeler dashboard by using the Run Migration Modeler link under the Actions heading on the action panel to the right of the Foglight for VMware browser interface. For more information about the action panel with respect to Foglight for VMware tasks and actions, refer to Accessing VMware actions and tasks .
•
From within any dashboard, you can access the VMware Modeler dashboard by clicking the VMware Modeler link under Dashboards > Virtual > VMware in the navigation panel.
Figure 53. Migration Modeler

The VMware Modeler dashboard provides four graphs that show current and projected numbers, for CPU and memory utilization and network and disk activity, on the target ESX Host over the time range specified in the VMware Explorer dashboard.

The blue area on the graphs represents current consumption or activity on the target ESX Host. The orange area specifies projected worst case consumption or activity. The red dotted line specifies the target ESX Host capacity with respect to the corresponding metric. For reference information about the data appearing on this dashboard, see VMware Modeler views .

To run the Migration Modeler:
1
From the VirtualCenter list, select the vCenter within which the migration will take place.
2
From the Virtual Machine list, select the virtual machine that is to be migrated.
3
From the Target Host list, select the ESX Host that will be the target for the migration.

When using the VMware Modeler dashboard, you should extend the time range in order to better assess the long term impact of the potential migration. For specific information about adjusting dashboard time ranges, refer to the Foglight for VMware User Guide.
