AD Replications Test
Replication is the process by which the changes that are made on one domain controller are synchronized with all other domain controllers in the domain that store copies of the same information or replica. Given the various types of information that Active Directory can store, changes to Active Directory can swiftly accumulate across multiple domain controllers in a large organization. It is therefore necessary for Windows to frequently synchronize the domain controllers through the replication process. If replication fails, it causes Active Directory objects that represent the replication topology, replication schedule, domain controllers, users, computers, passwords, security groups, group memberships, and Group Policy to be inconsistent between domain controllers. Directory inconsistency causes either operational failures or inconsistent results, depending on the domain controller that is contacted for the operation at hand.
To avoid such inconsistencies, its best to capture failures promptly, isolate the source of failures, and fix them, The AD Replications test aids in this regard. This test closely monitors the replication activities on the domain controller and promptly reports replication failures, so that administrators can investigate such failures, discover the reasons for the same, fix them, and restore normalcy.
Target of the test : An Active Directory or Domain Controller on Windows
Agent deploying the test : An internal agent
Outputs of the test : One set of results for every Active Directory server being monitored
Parameters | Description |
---|---|
Test period |
This indicates how often should the test be executed. |
Host |
The IP address of the machine where the Active Directory is installed. |
Port |
The port number through which the Active Directory communicates. The default port number is 389. |
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Replication failures |
Indicates the number of replication failures in the target domain controller. |
Number |
Ideally, the value of this measure should be low. |
Total replications |
Indicates the number of replication successes in the target domain controller. |
Number |
|
Percent replication failures |
Indicates the percentage of replication failures in the target domain controller. |
Percent |
Ideally, the value of this measure should be low. A high value is indicative of too many replication failures. Active Directory replication problems can have several different sources. For example, Domain Name System (DNS) problems, networking issues, or security problems can all cause Active Directory replication to fail.
