What do you see under RME --> Tools --> Syslog --> Syslog Collector Status
Is it showing any entries under any of the categories here?
You might want to enable debug for syslog:
Set logging level to "Debug" for SyslogAnalyzer and SyslogAnalyzerUI:
RME --> Admin --> System Preferences --> Loglevel Settings
Stop SyslogCollector and SyslogAnalyzer processes:
Common Services --> Server --> Admin --> Processes
In the $NMSROOT\MDC\tomcat\webapps\rme\WEB-INF\classes\com\cisco\nm\rmeng\csc\data\Collector.properties file, set "DEBUG_LEVEL=DEBUG".
Restart the above processes and then look in the SyslogCollector.log and SyslogAnalyzer.log for any errors or messages being written
