Use case – managing the overall SDDC performance

The target user for this use case is an SDDC overall architect.

This use case presents dashboards for someone who is keen on the overall infrastructure performance. This is typically the starting point of any performance troubleshooting, as one needs to know the overall situation before diving into a particular problem. This dashboard is not for the overall health. Health is more than performance. It takes into account anomalies and faults. Health is also affected when the capacity is near full, and it takes into account the vSphere HA setting.

The dashboard is suited for the overall SDDC architect, the person who will perform troubleshooting. However, the dashboard can be modified to suit other roles, such as the head of infrastructure.

As this is an overall dashboard, it needs to be complemented with a set of more detailed dashboards. The detailed dashboards will cover storage, network, and compute, separately. This dashboard just shows the...
