Measures reported by HvVMReplicaHTest
Windows Server 2012 Hyper-V Role introduces a new capability, Hyper-V Replica, as a built-in replication mechanism at a virtual machine (VM) level. Hyper-V Replica can asynchronously replicate a selected VM running at a primary site to a designated replica site across LAN/WAN.
To track the replication status of each VM and promptly capture errors in the replication process, administrators can use the HvVMReplicaHTest test.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Replica_state |
Indicates the replication state of this VM. |
|
The values that this measure can report and their corresponding numeric values are as follows:
| Measure Value |
Numeric Value |
| Error |
0 |
| FailOverWaitingCompletion |
1 |
| FailedOver |
2 |
| NotApplicable |
3 |
| ReadyForInitialReplication |
4 |
| Replicating |
5 |
| Resynchronizing |
6 |
| ResynchronizeSuspended |
7 |
| Suspended |
8 |
| SyncedReplicationComplete |
9 |
| WaitingForInitialReplication |
10 |
| WaitingForStartResynchronize |
11 |
Note:
By default, this measure reports the Measure Values in the table above to indicate replication state. In the graph of this measure however, the same will be represented using the numeric equivalents only.
The detailed diagnosis of this measure reports the primary server name, the replica server name, and the current replica server name of a VM. |
| Replica_health |
Indicates the replication health of this VM. |
|
The values that this measure can report and their corresponding numeric values are as follows:
| Measure Value |
Numeric Value |
| Normal |
0 |
| Warning |
1 |
| Critical |
2 |
Note:
By default, this measure reports the Measure Values in the table above to indicate replication health. In the graph of this measure however, the same will be represented using the numeric equivalents only. |
| Replica_mode |
Indicates the replication mode of this VM. |

3 |
Note:
By default, this measure reports the Measure Values in the table above to indicate replication mode. In the graph of this measure however, the same will be represented using the numeric equivalents only. |
| Last_replica_time |
Indicates how much time this VM took to replicate last. |
