Replication Test

As the number of domain controllers increase, the replication process consumes more network bandwidth. So, replication process should be monitored within the target environment.

Note:

This test applies only to Active Directory Servers installed on Windows 2003.

Target of the test : An Active Directory or Domain Controller on Windows 2003

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Active Directory server being monitored

Configurable parameters for the test
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.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
DRA inbound objects applied rate	This measure shows the number of replication updates applied per second that are occurring on this domain controller as a result of changes generated on other domain controllers.	Appld/Sec	A low value may indicate one of the following less changes to the objects in the other domains this domain controller is not applying the changes to the objects at the desired rate. If the object changes are not applied at the desired rate, it may result in a loss of data integrity in the Active Directory. Forcing the replication activity may solve this problem.
DRA inbound properties applied rate	This measure indicates the number of changes applied to object properties per second through inbound replication as a result of reconciliation logic. This logic is used to determine the final value to be replicated to the property.	Appld/Sec	A low value may indicate one of the following less changes to the object properties in the other domains this domain controller is not applying the change to the object properties at the desired rate. If the object properties are not applied at the desired rate, it may result in a loss of data integrity in the Active Directory. Forcing the replication activity may solve this problem.
DRA inbound objects filtered rate	This measure indicates the number of inbound replication objects received per second from the replication partners that contained no updates that needed to be applied.	Filtrd/Sec	A high value for this measure indicates that the objects are all static. Increasing the replication frequency may solve this problem.
DRA inbound properties filtered rate	This measure indicates the number of inbound replication properties received per second from the replication partners that did not contain any updates to be applied.	Filtrd/Sec	A high value for this measure indicates that the properties are all static. Increasing the replication frequency in the replicated domain may solve this problem.
DRA outbound objects filtered rate	This measure indicates the number of outbound replication objects that have not yet been received by the outbound replication partner per second.	kerFiltrd/Sec	A high value for this measure indicates that the objects are all static. Increasing the replication frequency in the target domain may solve this problem.
Pending replication synchronizations	This measure indicates the number of directory synchronizations that are queued per second for this domain controller but not yet processed.	Number	An unusually high value for a long duration may signify that the replication process is not being carried out at the desired rate. Forcing the replication activity may solve this problem.
