Hyper-V VM Replication Health Test

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 Hyper-V VM Replication Health test.

Note:

This test will report metrics for Microsoft Hyper-V Server 2012 only.

Target of the test : A Hyper-V / Hyper-V VDI server

Agent executing the test : An internal agent

Output of the test : One set of results for each VM on a Hyper-V host monitored

Configurable parameters for the test
Parameter	Description
Test period	This indicates how often should the test be executed.
Host	Specify the HOST for which this test is to be configured.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measures reported by the test:

Measurement

Description

Measurement Unit

Interpretation

Replication 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.

Replication 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.

Replication mode

Indicates the replication mode of this VM.

The values that this measure can report and their corresponding numeric values are as follows:

Measure Value	Numeric Value
Normal	0
Primary	1
Replica	2
TestReplica	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 replication time

Indicates the how much time this VM took to replicate last.
