Application Performance Analyzer for z/OS, Version 11.1, User's Guide

Performance graphs

These are histograms quantifying measurement data. To the right of some of the graphs, report codes of reports that show related and more detailed information are displayed. You can display the report by skipping the cursor to one of these fields and by pressing the ENTER key.

Most active IMS PSBs

Under Heading This is Displayed
Samples The number of samples done during the measurement upon which this graph is based. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph.
IMS™ PSB Name An IMS PSB name is shown and the number of samples in which processing of DL/I calls under this PSB was observed. The percentage and the graph represent the proportion of the overall measurement time DL/I calls were being serviced under this PSB.

Most active IMS transactions

Under Heading This is Displayed
Samples The number of samples done during the measurement upon which this graph is based. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph.
IMS Transaction Code An IMS transaction code is shown and the number of samples in which processing of DL/I calls under this transaction was observed. The percentage and the graph represent the proportion of the overall measurement time DL/I calls were being serviced in this transaction.

Most active DL/I calls

Under Heading This is Displayed
Samples The number of samples done during the measurement upon which this graph is based. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph.
DL/I Call A DL/I call identified by three fields: a unique sequence number assigned to the DL/I call, its DL/I function code and its PCB name. The percentage and the graph represent the proportion of samples in which processing this DL/I call was observed. The percentage and the graph represent the proportion the overall measurement time all executions of this DL/I call were being serviced.

Most CPU consumptive DL/I

Under Heading This is Displayed
Total DL/I CPU Time The number of seconds of CPU time consumed by all executions of DL/I calls during the measurement. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph.
DL/I Call A DL/I call identified by three fields: a unique sequence number assigned to the DL/I call, its DL/I function code and its PCB name. The quantification and the graph show the number of CPU seconds of execution for this DL/I call.

Most frequent transactions

This requires that the IMS+ measurement option is active and the execution of IMS transaction was observed. The graphic information is based on the number of transactions counted.

Under Heading This is Displayed
Total txns counted The total number of IMS transactions counted during the measurement. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph.
IMS transaction The IMS transaction code and the number of executions of this transaction.

Most frequent DL/I calls

This requires that the IMS+ measurement option was active. The graphic information is based on the number of DL/I calls counted.

Under Heading This is Displayed
Total DL/I calls counted The total number of DL/I calls counted during the measurement. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph.
DL/I call A DL/I call identified by three fields: a unique sequence number assigned to the call, its DL/I function code and its PCB name. The number of executions of this call is quantified.
