The Logs and Status page contains the settings for the Domain Time service text log.
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.
Logs are kept in the %SystemRoot%\System32\ folder. There are at least three main log files collected when the service is running:
domtimec.log
This is the currently active text log file.
If log archiving is enabled (see below), additional archived log files will be created using a
domtimec.log.startup
A detailed text log of the service startup process. Only data from the latest startup is included.
To view these two text logs, click the button on the applet, which launches the Domain Time Log Viewer.
drift.dt
A binary file containing information on each time check/correction used to display the drift graph. Drift logs can also collected remotely by Domain Time Audit Server.
To view this log, click the button on the applet, which launches the Domain Time Drift Log Viewer.
This section selects the properties of the domtimec.log service text log.
The Log Level drop-down chooses what type of entries to include in the log. You can increase or decrease the amount of information logged as needed.
The available levels are (in increasing amount of detail):
Disabled
This switch will only disable the domtimec.log file. Other system logs, such as domtimec.startup.log and drift.dt cannot be disabled.
Errors Only messages marked as Errors will be logged
Warnings Logs will include Errors and Warnings
Information Includes Errors, Warnings, and information on the activity of the time service, such as time sources contacted, amount of clock correction, etc.
Trace Includes all of the above, plus detailed information on time setting and time sample analysis.
Debug Includes all available information provided by the service.
CAUTION: Debug logging will generate a great deal of data, so be sure to only enable it
when you need the additional information, and don't forget to turn it off when finished troubleshooting.
Max size: sets how large the log file is allowed to grow (in kilobytes).
Once the maximum size is reached, the oldest events will be scrolled off to make room for new events. Enter 0 (zero) if you don't want to limit the log size.
It's a good idea to set a log size that will allow you to keep enough history to troubleshoot any issues that may arise.
Include client accesses (requests for time or control messages)
When checked, all client requests made of this server will be logged.
CAUTION: Enabling this option can generate a large amount of logging data if you have a lot of clients synchronizing with this server.
Examine the log after the server has been running for a while to see if this option generates an onerous amount of data.
Enable UDP packet tracing Enable TCP packet tracing
These checkboxes cause Domain Time to log additional useful details about the time packets being used by Domain Time.
CAUTION: Enabling this option can generate a large amount of logging data.
You should enable these only when actively troubleshooting network issues.
Domain Time can automatically archive the text log on a daily, weekly, or monthly schedule.
When the log is archived, all existing log events in the domtimec.log
file will be written to an archive file named
domtimec.YYYYMMDD.log (i.e. domtimec.20090928.log) and the current log file will then be cleared to accept new data.
You can choose how many archived log files to keep on the machine. When the indicated limit is reached, the oldest log file will be deleted.
