Intra-Site Replication Test

Intra-site replication means replication happening between domain controllers in the same site. Intra-site replication attempts to complete in the fewest CPU cycles possible. Intra-site replication avoids unnecessary network traffic by introducing a change notification mechanism that replaces the usual polling of replication partners for updates. When a change is performed in its database, a domain controller waits for a configurable interval (default 5 minutes) and accepts more changes during this time. Then it sends a notification to its replication partners, which will pull the changes from the source. If no changes are performed for a configurable period (default 6 hours) the domain controller initiates a replication sequence anyway, just to make sure that it did not miss anything.

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
In rate	This measure indicates the number of inbound kilobytes replicated within the site per second.	KB/Sec	A high value for this measure indicates that the intra-site replication traffic is high.
Out rate	This measure indicates the number of outbound kilobytes replicated within the site per second.	KB/Sec	A high value for this measure indicates that the intra-site outbound replication traffic is high.
