This page contains options for additional features to monitor the Domain Time service in real-time.

Note: If you see the Group Policy applied indicator in the lower-left corner of the applet, there are settings on this page that are being overridden by an Active Directory Group Policy. Settings controlled by policy may be greyed-out or you may be otherwise prevented from making a change here. See the Active Directory page for more information on using Group Policies.

Domain Time Server and Client are designed to be centrally monitored and have their synchronization status recorded by Domain Time Audit Server. This is usually done by Audit Server in a scheduled, background data collection process.

However, Domain Time II Server and Client can send an immediate notification packet to Audit Server containing feedback on the success or failure of each time check to provide real-time monitoring and alerting. If you want this function, check the Enabled checkbox and enter the DNS name or IP address of your Audit Server.

See the Audit Server pages for more information.

CAUTION:


---

If you are using notifications on many machines that are set to synchronize frequently, the feature can generate a significant amount of network traffic toward your Audit Server. You will probably want to enable instant notifications only on critical systems where an immediate alert of time sync errors is desired.

Otherwise, you should use Audit Server's normal scheduled sync log collection instead, which is much more efficient. Audit Server's sync log collection can run in a background process to gather all sync records from audited systems with much less impact on overhead than active notifications. Audit Server can be programmed to provide alerts based on that data as well.

The Service Status Monitor section controls whether Domain Time will provide a simple text response about its current status when asked by an application.

If you need more sophisticated monitoring and status than provided above, Domain Time Server and Client (as of version 5.1) provide a documented API (Application Programming Interface) so that developers can have programmatic access to a number of Domain Time internal features. In addition to service status, the most important feature of the API is the ability to have direct access to the same high-resolution corrected system time Domain Time uses to manage the clock.

Using the pre-compiled .dlls (32-bit or 64-bit) from the SDK, programs can make a simple API call in their native language to obtain date/time accurate, monotonically-incrementing hectonanosecond-resolution timestamps without any additional programming. There's no need to design your own timing and interpolation routines or to navigate Windows' labyrinthine timer and system clock internals. The SDK includes the .dlls and sample code in a variety of programming languages so you can be up-and-running with hectonanosecond-resolution timestamps immediately.

See the Software Development Kit (SDK) page for more details and information on obtaining the SDK.
