We are using IBM SMF120 records to view beans, servlets, servers, response and cpu times on the mainframe. All in an historical view as we cut the records and store them in a Tivoli database. I know there are PMI statistics for the distributed side. I know there is Tivoli Netview Viewer. It seems that running PMI is not recommended to be running all the time. What is out there to view the beans, servlets, server performance, response times in an historical frame of reference?
