eG Monitoring

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. The measures made by this test are as follows:
Measurement | Description | Measurement Unit | Interpretation

No_of_vm_deleted | Indicates the number of VMs that are deleted. | Number | Used the detailed diagnosis of this measure to know the name and status of each VM that is deleted, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_error | Indicates the number of VMs that encountered unrecoverable error. | Number | Ideally, the value of this measure should be 0. Used the detailed diagnosis of this measure to know the name and status of each VM that encountered errors, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_paused | Indicates the number of VMs that are currently paused with a specific image. | Number | Used the detailed diagnosis of this measure to know the name and status of each VM that is in ‘Paused’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_rescued | Indicates the number of VMs that are currently running with the rescue image. | Number | Used the detailed diagnosis of this measure to know the name and status of each VM that is currently running with rescue image, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
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. Used the detailed diagnosis of this measure to know the name and status of each VM that is in ‘RESIZED’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_shelved | Indicates the number of VMs that are currently in the SHELVED state. | Number | Shelved VMs can be in one of two possible states: shelved and shelved_offloaded. If a VM is in the shelved state, then it indicates that the VM is still present on the target hypervisor but is in inactive state. When the VM is moved to in shelved_offloaded state, it indicates that the VM has been removed from the hypervisor and the resources allocated to the VM are released. Used the detailed diagnosis of these measures to know the name and status of each VM that is in ‘SHELVED_OFFLOAD’ and ‘SHELVED’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_shelved_off | Indicates the number of VMs that are currently in the SHELVED_OFFLOAD state. | Number | Shelved VMs can be in one of two possible states: shelved and shelved_offloaded. If a VM is in the shelved state, then it indicates that the VM is still present on the target hypervisor but is in inactive state. When the VM is moved to in shelved_offloaded state, it indicates that the VM has been removed from the hypervisor and the resources allocated to the VM are released. Used the detailed diagnosis of these measures to know the name and status of each VM that is in ‘SHELVED_OFFLOAD’ and ‘SHELVED’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_soft_delete | Indicates the number of VMs that are currently in the SOFT_DELETED state. | Number | A VM is moved to the SOFT_DELETED state, when the VM is no longer running on the hypervisor but the image of the VM remains on the disk so that the VM can be configured again. Used the detailed diagnosis of this measure to know the name and status of each VM that is in ‘SOFT_DELETED’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_stopped | Indicates the number of VMs that are currently in the STOPPED state. | Number | The STOPPED state is reported when the VM is stopped working completely but the image of the VM is still available on the disk. Used the detailed diagnosis of this measure to know the name and status of each VM that is in ‘STOPPED’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
No_of_vm_suspended | Indicates the number of VMs that are currently in the SUSPENDED state. | Number | The state of VM is reported as SUSPENDED when the VM is suspended with the specified image, with a valid memory snapshot. Used the detailed diagnosis of this measure to know the name and status of each VM that is in ‘SUSPENDED’ state, IP addresses and host name of each VM, name of the availability zone, key name, date at which the VM was created, ID of each VM, ID of the project, flavor ID, and image ID.
