Make sure the SyslogCollector and SyslogAnalyzer processes are running, and check that the Analyzer is subscribed to the Collector under RME > Tools > Syslog > Syslog Collector Status. Make sure that the messages being written to the log are valid syslog messages. You want to see the Forwarded count increasing the the Syslog Collector Status. Additionally, check your filters to make sure you are not filtering out the messages arriving in the syslog.log.
