Files Produced by JPROF

JPROF can generate a variety of files, based on the options that are specified. By default, all of the files are placed in the current directory and use "log" as a prefix, such as log-msg.

The logpath=path option can be used to select a different directory, while the logprefix=prefix option will change the prefix used to create the filenames. For example, if logpath=abc,logprefix=def is specified, then log-msg would be replaced by abc/def-msg.

Unless you specify nopidx, all of the files will use a _PID extension, such as log-msg_1234 for process 1234.

The types of files produced by JPROF and their contents are:
