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

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 is a performance profiler tool for Linux.
ocount is an event counting tool for Linux.
opreport gives image and symbol-based profile summaries for the whole
system or a subset of binary images.
opannotate can produce annotated source or mixed source and assembly
output.
oparchive produces oprofile archive for offline analysis
opgprof can produce a gprof-format profile for a single binary.
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.
No special environment variables are recognized by OProfile.
