There are a lot of free syslog tools available that can collect and show this collected information in GUI, however the GUI may differ. Also these tools may not provide you the syslog grouping using severity levels like what is given by the RME syslog analysis. You can use syslog.log file with any of the free tools but to get the same summary report you will have to put the file in NMSROOT and use syslog analysis to generate the report.
