You may choose to have Domain Time send service activity events to Syslog servers.
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.
The Server: field should contain the DNS Name or IP address of the Syslog Server(s).
As of v5.2.20170922, you may list up to eight targets on the Syslog Server line. Older versions only support a single target. Separate
targets with a space.
Important: If you will be assigning this value using Templates
or Active Directory Policies to any Server or Client version
older than v5.2.b.20170922, the first entry of a multiple target list MUST be an IPv4 address, otherwise the older version will read the field
incorrectly. For maximum backward compatibility with older versions of Domain Time, avoid using a DNS name if you list more than one
target. If all of your machines have been upgraded, then you may use either DNS names or IPv4 addresses for your targets.
The Log Level drop-down chooses what type of entries to include in the Syslog logs. You can increase or decrease the amount of information logged as needed.
The available levels are (in increasing amount of detail):
Domain Time will not log events to the Syslog server.
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.
RFC 3264 format
RFC 5424 format (UDP only)
Include timeQuality structured data element
Added as of version 5.2.b.20171113. Use these radio buttons to select the RFC format that matches your syslog server.
If the Include timeQuality structured data element checkbox is checked, the output will include timeQuality information, for example:
[timeQuality tzKnown="1" is Synced="1"]
Send each PTP data point to syslog (trace or debug level only):
Added as of version 5.2.b.20180101. If checked, and if the syslog level is set to either trace or debug, then each PTP data point will be sent to syslog.
The format is
PTP sample offset ±0.0000000, mpd 0.0000000, source ipaddress where 0.0000000 is that sample's delta
and the current meanPathDelay. Syslog log collectors may parse for trace-level messages beginning with "PTP sample offset"
to categorize these messages.
Caution: Enabling this output can create a large number of syslog messages. Enable only if you actually require this level of detail.
You may want to enable lazy writes if you find the logging process is affecting your clock accuracy. See the Logs and Status page to enable lazy writes.
