Snapshots preserve the state and data of a virtual machine at the time you take the snapshot. You can view the snapshots status using the Snapshots card in the Diagnostics for VMware Cloud Foundation.

Using Diagnostics for VMware Cloud Foundation you can:
  • See all snapshot creation events along with their status.
  • For each failure view the failure reason.
  • View every virtual machine (VM) that requires the consolidation of snapshots. In cases where the file containing snapshot information is incorrect or corrupt, vSphere indicates that a VM requires consolidation. This file does not contain any virtual disk data.
The Findings section displays findings by analyzing the logs for snapshot-related events collected from vCenter instances, ESXi hosts, and VMs.

To investigate snapshot failures, you can use the trend chart at the top of the Snapshots page to gain an understanding of which users are triggering the failures and in which VMs and vCenter instances. Then, follow the troubleshooting flow provided in What is Diagnostics for VMware Cloud Foundation.
