New Trace Statistics window graphically provides the big picture

The new Trace Statistics window allows users to see detailed information about program and file I/O, pool usage, memory and heap usage, macros, and instructions in an easy-to-understand graphical format.

To use the Trace Statistics window, programmers first set up trace options, then run a transaction.

Figure 1: The Program & File I/O page of the new Trace Statistics window.

The new window has five pages. The Program and File I/0 page displays a pie chart depicting the number of programs called in from file versus the number of programs called in from core.

The Pool Usage page shows the number of pools acquired and released and can be filtered based on record size and term.

The Memory/Heap Usage page shows the amount of common and private storage for each type of memory block.

The Macro Statistics page displays a list of macros and how many times they were encountered.

The Instruction Statistics displays a table showing all instructions and the number of times each has been encountered, as well as a bar graph that compares the count for one or more individual instructions to the total number of instructions encountered.
