Measures reported by ADReplStatusTest
This test summarizes the replication state and relative health of an Active Directory forest by inventorying and contacting every domain controller in the forest, and collecting and reporting information such as replication deltas and replication failures. You can thus accurately identify the domain controllers that are prone to frequent failures.
Output of the test : One set of results for every domain controller in an Active Directory forest being monitored
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Total |
Indicates the number of replica links for this domain controller. |
Number |
A replica link exists for each naming context on a domain controller. This measure is the sum total of such replica links per domain controller. Please note that this is not the connection objects or replication partners per domain controller.
You can use the detailed diagnosis of this measure to view the complete details of the replica links - this includes the source and destination sites, the source and destination domain controllers, the transport type, the number of link failures (if any), and details of the failures such as when the failure occurred and the failure status. |
| Fails |
Indicates the total number of replica links on this domain controller that are failing to replicate for one reason or the other. This will never be greater than the Total field. |
Number |
Ideally, the value of this measure should be 0. |
| Fails_pct |
Indicates the percentage of failures in relation to the total replica links on this domain controller. |
Percent |
A low value is desired for this measure. A value close to 100% is a cause for concern, as it indicates that almost all replica links are failing. |
| Largest_delta |
Denotes the longest replication gap amongst all replication links on this domain controller. |
Secs |
Ideally, this value should be less than 1 hour. |
