Ah, that is interesting. If I'm reading this correctly, I should see a type 7 record when the system loses other SMF records. So, seeing no type 7 record indicates that no records were lost. And there is no type 7 in the dump for that day.
We converted to logstream recording of SMF data back in March and have not had any messages on the console about buffer shortages in SMF recording the way we did periodically when we used the VSAM files.

Record Type 7 (07) - Data Lost z/OS V1R12.0 MVS System Management Facilities (SMF) SA22-7630-22 If all SMF buffers become full (either a result of no available output data sets for SMF to write to OR the system generating records at a rate faster than SMF can physically write them), SMF data will be lost. When this condition occurs, record type 7 tracks the number of lost records. It contains a count of the SMF records that were not written and the start and end times of the period when data was lost. (The end time is the time recorded in SMF7TME at offset 6). Record type 7 is not built until SMF buffers become available again. Data existing in the SMF buffer, prior to data lost, is written to available SMF data sets before record type 7 is written to a data set. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
