This test measures the load on the AD server in terms of the level of read-write activity on the server and the count of search operations performed by the server. In the process, the test reveals the following:

• Which AD services initiated the read-write operations? Which of these services generated the maximum I/O load on the server - is it the LSA? the NSPI? the NTDS? SAM? or the replication service? - this information is useful when administrators are faced with an AD overload, as it accurately points them to the probable sources of the load;
• Which AD service performed the maximum searches on the server? - in the event of an overload, this metric will help you identify that service which could be contributing to the overload;
• Is the server sized with adequate threads to handle the I/O load?

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

This page depicts the default parameters that need to be configured for the ADAccessDetTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
