Option details:
summary: Instructs the formatter to produce only summary information about the data
input_file: The binary trace file generated by IBM JVMs. For multi-generational trace files specify the file pattern instead. This option is required
debug: If specified this option will cause debug data to be written to stderr. The default debug level is 1, increasing this will increase the amount of data supplied.
datfile: A comma separated list of files containing the trace format strings. By default the following files are used:
$JAVA_HOME/lib/J9TraceFormat.dat
$JAVA_HOME/lib/OMRTraceFormat.dat
format_time: Specifies whether to format the tracepoint time stamps. Default is yes.
indent: Specifies whether to indent the trace point text to illustrate the call flow for the thread.
timezone: Specifies the offset from UTC/GMT to apply when formatting timestamps, as +|-HH:MM
threads: A comma separated list of thread ids to include in the formatted trace output.
output_file: The output file containing the formatted trace data. The default is to append ".fmt" to the input file name
verbose: If specified this option will cause warning and error messages to be printed to stderr. By default a count of each is displayed
statistics: If specified this will cause some statistics to be reported:
bytes of data by component
total bytes
hit counts by trace point
bytes of data by trace point
