PROGRAM:

NAME


oprofile - a statistical profiler for Linux systems, capable of profiling all running code
at low overhead; also included is a set of post-profiling analysis tools, as well as a
simple event counting tool

SYNOPSIS


operf [ options ]
ocount [ options ]
opreport [ options ] [ profile specification ]
opannotate [ options ] [ profile specification ]
oparchive [ options ] [ profile specification ]
opgprof [ options ] [ profile specification ]

DESCRIPTION


OProfile is a profiling system for systems running Linux 2.6.31 and greater. OProfile
makes use of the hardware performance counters provided on Intel, AMD, and other
processors. OProfile can profile a selected program or process or the whole system.
OProfile can also be used to collect cumulative event counts at the application, process,
or system level.
For a gentle guide to using OProfile, please read the HTML documentation listed in SEE
ALSO.

OPERF


operf is a performance profiler tool for Linux.

OCOUNT


ocount is an event counting tool for Linux.

OPREPORT


opreport gives image and symbol-based profile summaries for the whole system or a subset
of binary images.

OPANNOTATE


opannotate can produce annotated source or mixed source and assembly output.

OPARCHIVE


oparchive produces oprofile archive for offline analysis

OPGPROF


opgprof can produce a gprof-format profile for a single binary.

PROFILE SPECIFICATIONS


Various optional profile specifications may be used with the post-profiling tools. A
profile specification is some combination of the parameters listed below. ( Note:
Enclosing part of a profile specification in curly braces { } can be used for differential
profiles with opreport, but the braces must be surrounded by whitespace.)

archive:archive
Path to the archive to inspect, as generated by oparchive

session:sessionlist
A comma-separated list of session names to resolve in. Absence of this tag, unlike
all others, means "the current session", equivalent to specifying
"session:current".

session-exclude:sessionlist
A comma-separated list of sessions to exclude.

image:imagelist
A comma-separated list of image names to resolve. Each entry may be relative path,
glob-style name, or full path, e.g. opreport 'image:/usr/bin/operf,*op*,./oprofpp'

image-exclude:imagelist
Same as image:, but the matching images are excluded.

lib-image:imagelist
Same as image:, but only for images that are for a particular primary binary image
(namely, an application). This only makes sense to use if you're using --separate.
This includes kernel modules and the kernel when using --separate=kernel.

lib-image-exclude:imagelist
Same as <option>lib-image:</option>, but the matching images are excluded.

event:eventname
The symbolic event name to match on, e.g. event:DATA_MEM_REFS.

count:eventcount
The event count to match on, e.g. event:DATA_MEM_REFS count:30000.

unit-mask:maskvalue
The unit mask value of the event to match on, e.g. unit-mask:1.

cpu:cpulist
Only consider profiles for the given numbered CPU (starting from zero). This is
only useful when using CPU profile separation.

tgid:pidlist
Only consider profiles for the given task groups. Unless some program is using
threads, the task group ID of a process is the same as its process ID. This option
corresponds to the POSIX notion of a thread group. This is only useful when using
per-process profile separation.

tid:tidlist
Only consider profiles for the given threads. When using recent thread libraries,
all threads in a process share the same task group ID, but have different thread
IDs. You can use this option in combination with tgid: to restrict the results to
particular threads within a process. This is only useful when using per-process
profile separation.

ENVIRONMENT


No special environment variables are recognized by OProfile.
