Address Book Details Test

The Address Book is a client for the Active Directory database. It performs lookups and search operations on the Active Directory database to look for details such as account email ID, and so forth. Using the Address Book Details test, you can determine the number of Address Book clients currently connected to the AD database and the rate at which search operations are performed by each AD server. In the event that the AD database gets inundated with search queries, you can use this test to figure out whether or not the Address Book clients are contributing to the query load.

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 site that is being monitored

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

Client sessions

Indicates the number of client sessions that are currently connected to the AD database.


A high value is indicative of heavy load. A consistent increase in the value of this measure could indicate a potential overload condition.

Search operations

Indicate the rate at which the key search operations are performed on the AD database.


If the value of this measure decreases while the number of Client sessions keeps increasing, it indicates that search queries are not been processed as quickly; this in turn is indicative of a processing bottleneck, which can consequently choke the AD server database.
