Enabling Timestamp on Syslog Messages

By default, syslog messages include a time/date stamp, taken from the datetime, stating when the error or message was created.

To enable timestamp, use the following command.
Add timestamp to syslog messages.
CONFIGURATION mode
service timestamps [log | debug] [datetime [localtime] [msec] [show-timezone] [utc] | uptime]
Specify the following optional parameters:
  • datetime: To view the timestamp in system local time that includes the local time zone.
  • localtime: You can add the keyword localtime to view timestamp in system local time that includes the local time zone.
  • show-timezone: Enter the keyword to include the time zone information in the timestamp.
  • msec: Enter the keyword msec to include milliseconds in the timestamp.
  • uptime: To view time since last boot.
  • utc: Enter the keyword utc to view timestamp in UTC time that excludes the local time zone.
If you do not specify a parameter, Dell EMC Networking OS configures datetime as localtime by default.

To view the configuration, use the show running-config logging command in EXEC privilege mode.

To disable time stamping on syslog messages, use the no service timestamps [log | debug] command.
