Abstract:
A computer-implemented method for analyzing input/output operations of a data processing system hosting one or more programs, comprising:storing input/output trace data of the system in records of an input/output trace file in time sequence order, the trace data characterizing input/output operations performed on the system, and the trace data for each operation being stored in a separate record having a plurality of data fields the trace file having a first record and a last record; organizing the trace file in a plurality of blocks, each block including a plurality of records and the blocks ordered by times of records of the input/output trace data: interactively obtaining data selection criterion, wherein the data selection criterion includes one of the group of a block number selection and a record index selection; reading input/output trace data from the trace file in accordance with the selection criterion; displaying the input/output trace data read from the trace file; and repeating the steps of obtaining the data selection criteria and displaying the trace data.
