Exchange Replication Health Test

This test checks all aspects of replication and replay and reports on the health of each aspect. It is designed for the proactive monitoring of continuous replication and the continuous replication pipeline, the availability of Active Manager, and the health and status of the underlying cluster service, quorum, and network components.

Target of the test : A server configured with the Mailbox server role

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each aspect of replication that is tested.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

Indicates the IP address of the Mailbox server.

Port

The port number through which the Mailbox server communicates. By default, this is 6001.

XchgeXtensionShellPath

The Exchange Management Shell is a command-line management interface, built on Windows PowerShell which enables you to administer every part of Microsoft Exchange. This test uses the Exchange management shell to run scripts and collect the desired performance metrics from the Exchange server. By default, the test auto-discovers the location of the Exchange management shell and thus, automatically loads the Exchange management shell snap-in (exshell.psc1) for script execution. This is why, the XchgeXtensionShellPath is set to none by default.

TransientEvent
SuppressionWindow

This parameter specifies the number of minutes that the queue lengths can be exceeded before the queue length tests are considered to have failed. This parameter is used to reduce the number of failures due to transient load generation. By default, this parameter is set to 3 minutes.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Mailbox replication service status

Indicates the connectivity status of this aspect of replication.

 

If the value of this measure is Success, it indicates that this replication aspect is in good health currently. If the value of this measure is Failure, it indicates problems in this replication aspect. The numeric values that correspond to these measure values are as follows:

Measure Value Numeric Value
Success 1
Failure 0

If the status reported by this measure is Failure, you can use the detailed diagnosis of this test to determine the reason for the failure.

Note:

Typically, this measure reports the Measure Values listed in the table above to indicate status of each replication-related activity that is monitored. However, in the graph of this measure, the Numeric values are used to represent replication health.

If some aspect related to replication reports the status as Failed, you can use the detailed diagnosis of the Exchange Replication Health test to view the error that caused the failure.
