OpenStack Overview dashboard
The OpenStack dashboard provides a top-down overview of an entire OpenStack environment from an OpenStack Cloud entity prospective. The available OpenStack Cloud entities to be selected are reflective of the same OpenStack Cloud entities within the client's BMC Helix Continuous Optimization (HCO) environment.
Within the dashboard the following capacity insights are presented:
- Aggregated Utilization values over the last 30 days for the following metrics: CPU, Memory, and Storage
- Total count of all underlying OpenStack entities related to the selected OpenStack Cloud
- Capacity related metrics displayed in a timeseries chart
- Related Regions placed in table which displays informational capacity related metrics
- Related Availability Zones placed in table which displays informational capacity related metrics
- Related Host Aggregates placed in table which displays informational capacity related metrics
- Related Hypervisors placed in table which displays informational capacity related metrics
- Related Instances (VMs) placed in table which displays informational capacity related metrics
- Related Tenants placed in table which displays informational capacity related metrics
