SMF Dump Data

RMF™ writes performance measurement data into SMF records, from which the Postprocessor extracts the reports or metrics by producing Report Listings or Overview Records. SMF data from two sources can be used as input to the Postprocessor:

• SMF records from SMF dump data sets: SMF dump data is usually stored in generation data groups (GDGs). With the Spreadsheet Reporter, these data sets can be defined as remote resources of type SMF Dump Data.
• SMF records from the RMF Sysplex Data Server's SMF buffer: This is a wrap-around buffer, used by RMF to store copies of SMF records written to the SMF dump data sets.

When you create Working Sets, Report Listings, XML Reports, or Overview Records, you determine which type of SMF data the Postprocessor should use: If you do not select any SMF Dump Data resource, then the Postprocessor automatically extracts the requested data from the RMF Sysplex Data Server's SMF buffer.
