Measures reported by OSHvVmStatusTest
This test continuously the target OpenStack KVM hypervisor and reports the count of virtual machines (VMs) that are in different states. This test enables administrators to instantly determine how many VMs are currently running on the target hypervisor and how many VMs are deleted/stopped/paused/suspended. In addition, the test also reveals the count of VMs that encountered unrecoverable errors. Using the metrics reported by this test, administrators can promptly identify the reason for inaccessibility of the VMs whenever users complain of the same.
Outputs of the test: One set of results for the target hypervisor.

| No_of_vm_error |
Indicates the number of VMs that encountered unrecoverable error. |
Number |
Ideally, the value of this measure should be 0.

| No_of_vm_resized |
Indicates the number of VMs that are currently in the RESIZED state. |
Number |
If a VM is in the RESIZED state, then it indicates that the VM is stopped on the source node but running on the destination node. The VM images exist at both source and destination locations with different sizes. The user is expected to confirm the resize or revert it.

|
| No_of_vm_soft_delete |
Indicates the number of VMs that are currently in the SOFT_DELETED state. |
