Syslog events are generated based on /var/log/syslog entries. If a specific pattern is observed in the syslog file, then it generates the syslog event. The application reads syslog_config.json file for parameter values and poppulate the syslog event. If eventName, eventSourceType, syslogTag and tmp_syslogFile parameter value is not given, the application terminates.
