The $level in the syslog is the log level, which includes: Log_emerg system is Unusablelog_alert action must be taken Immediatelylog_crit critical conditionslog_err error conditions Log_warning WARNING Conditionslog_notice Normal, but significant, conditionlog_info informational Messagelog_debug Debug-level message The second parameter is a specific log content.
