Measures reported by ADAddBookDetTest

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 ADAddBookDetTest 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.

This test applies only to Active Directory Servers installed on Windows 2008.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
AB_client_session Indicates the number of client sessions that are currently connected to the AD database. Number A high value is indicative of heavy load. A consistent increase in the value of this measure could indicate a potential overload condition.
AB_searches Indicate the rate at which the key search operations are performed on the AD database. Searches/Sec 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.
