The data is in the SMF 41 records. If you have MXG (and SAS) it's as
simple as this:
%INCLUDE SOURCLIB(TYPE41);
RUN;
PROC SORT NODUP DATA=TYPE41VF OUT=T41;
BY SYSTEM SMF41CLS SMFTIME;
PROC PRINT LABEL SPLIT='*';
VAR SMFTIME SYSTEM SMF41LRG SMF41MVT SMF41USD
SMF41ADD SMF41DEL SMF41TRM VLFHITPC;
BY SYSTEM SMF41CLS;
ID SMF41CLS;
FORMAT SMFTIME DATETIME18.;
TITLE 'VITUAL LOOKASIDE FACILITY';
TITLE2 'AS REDUCED FROM SMF TYPE41';
FOOTNOTE 'ZELDEN-(MXG41VLF)';
