System Log Message Format

System log messages can contain up to 80 characters and a percent sign (%), which follows the optional
sequence number or timestamp information, if configured. Messages are displayed in this format:
seq no:timestamp: %facility-severity-MNEMONIC:description
The part of the message preceding the percent sign depends on the setting of the service
sequence-numbers, service timestamps log datetime, service timestamps log datetime [localtime]
[msec] [show-timezone], or service timestamps log uptime global configuration command.
