Setting Up and Managing SMF Recording to Logstreams

If you choose to record your SMF records in log streams, you must define log streams, coupling facility structure space (for coupling facility log streams) and DASD space for offloading the log stream data. You will also need to define authorization for your log streams. The following topics guide you through the set-up process:

Requirements for using SMF logging
Planning your SMF logging configuration
Define authorization to SMF logging resources
Define SMF logging resources in the LOGR and CFRM policy couple data sets
Managing log streams and SMF log stream data
Sharing an SMFPRMxx parmlib member in an SMF logging environment
Using SMF log streams
Dumping SMF data from log streams

Hold on! Don't delete those SYSx.MANx data sets!

If you intend to switch from SMF data sets to SMF logging, do not delete any of your SMF data sets - you should retain these as a fallback option. You can just add SMF logging to your SMF data set configuration in an SMFPRMxx member and dynamically switch between recording to data sets and log streams. See Switching between SMF logging and SMF data set recording.
