Maps page in the OpenStack view
The Maps page in the OpenStack view provides a graphical representation of OpenStack cloud capacity.
To access this page, in the TrueSight console, select Capacity > Views > Cloud > OpenStack and click the Maps tab.
The page shows following metrics for the cloud. All values are calculated over the last full month, and the current month.
- CPU Utilization
- Memory Utilization
- Datastore Utilization
- vCPU Density
The parent entity in the Maps page is the cloud. After drilling down, you can view the region, availability zone, host aggregate, and hypervisors represented as child entities.
This representation is implemented by using a data visualization tool called Tree Maps. The Tree Map view displays system entities in a hierarchical order by using a series of clustered rectangles, which together represent a whole system.
You can easily and quickly view the details of an entity and drill down to view the child entity.
For example, in the Maps page, click the entity (specific cell in the map).
A Details window opens that lists the Name, Type, Utilization (%) and Size of the entity, along with Related Information links.
In the Details window, click Drill Down.
The child entity is displayed. The bread crumbs on top of the map indicate the entity you are currently viewing.
For more information about using the view, see Reading a tree map view.
