Significant system events are captured in log messages (also called syslog messages), which you can view on the console, save to a file, forward to an external server such as a syslog server, or direct to the terminal session of one or more specific users.
Depending on the level of message severity you choose to log, system log messages include notices of ordinary and routine operations as well as warnings, failure, and error messages.
The logging function of the vRouter uses the UNIX syslogd process. Logging configuration performed within the system CLI is stored in the /etc/sylogd.conf file.
By default, local logging is enabled and sends messages to the /var/log/messages file.
