If you are after the messages that sysloggtw probe receives from the devices, go to sysloggtw probe GUI in IM and check Send to log-file option. This will allows you to save the incoming Syslog messages to the log file specified in the File Name box.
Otherwise, run the following query on UIM DB to get the history for alarm messages.
select * from NAS_TRANSACTION_LOG where prid = 'sysloggtw' order by time desc
