Summary :
SAP Note addresses enhancements in workload analysis via transaction ST03 in the R/3 environment. It outlines the use of statistical data records from the "stat" file, managed by the COLLECTOR_FOR_PERFORMANCEMONITOR job, for system analytics. The note details a user exit in the statistics collector that allows access to raw statistical data beyond the default, compressed metrics typically used for ST03 evaluation. This feature supports specialized analyses on specific transactions or dialog steps. From SAP_BASIS 700 onwards, the user exit is replaced by a BADl implementation, ensuring compatibility and extended functionality in newer system versions.
Key words :
dialog step respti = response time cputi = cpu time queueti = wait time tasktype = task type, bytes requested = dsqlcnt + abapscnt + dynplcnt + cualcnt + abaplcnt + dynpscnt + ddiccnt + ntabcnt + quecnt, sli_cnt = abascnt + abaplcnt + dynplcnt + dynpscnt + ddiccnt + cualcnt + ntabcnt, time = committi + insti + delti + updti + readdirti + readseqti, db requests = readdircnt + readseqcnt + inscnt + updcnt + delcnt, db calls = readdirrec + phyreadcnt + phyinscnt + phydelcnt + phyupdcnt, bytes requested = dsqlcnt + quecnt + sli_cnt, dialog step starttime = start time, average cpu time, task type numbers
