CALLGRIND CONTROL(1) Release 3.13.0 CALLGRIND CONTROL(1)
callgrind_control - observe and control programs being run by
Callgrind
callgrind_control [options] [pid|program-name...]
callgrind_control controls programs being run by the Valgrind tool
Callgrind. When a pid/program name argument is not specified, all
applications currently being run by Callgrind on this system will be
used for actions given by the specified option(s). The default action
is to give some brief information about the applications being run by
Callgrind.
-h --help
Show a short description, usage, and summary of options.
--version
Show version of callgrind_control.
-l --long
Show also the working directory, in addition to the brief
information given by default.
-s --stat
Show statistics information about active Callgrind runs.
-b --back
Show stack/back traces of each thread in active Callgrind runs.
For each active function in the stack trace, also the number of
invocations since program start (or last dump) is shown. This
option can be combined with -e to show inclusive cost of active
functions.
-e [A,B,...] (default: all)
Show the current per-thread, exclusive cost values of event
counters. If no explicit event names are given, figures for all
event types which are collected in the given Callgrind run are
shown. Otherwise, only figures for event types A, B, ... are
shown. If this option is combined with -b, inclusive cost for the
functions of each active stack frame is provided, too.
--dump[=<desc>] (default: no description)
Request the dumping of profile information. Optionally, a
description can be specified which is written into the dump as
part of the information giving the reason which triggered the
dump action. This can be used to distinguish multiple dumps.
-z --zero
Zero all event counters.
-k --kill
Force a Callgrind run to be terminated.
--instr=<on|off>
Switch instrumentation mode on or off. If a Callgrind run has
instrumentation disabled, no simulation is done and no events are
counted. This is useful to skip uninteresting program parts, as
there is much less slowdown (same as with the Valgrind tool
"none"). See also the Callgrind option --instr-atstart.
--vgdb-prefix=<prefix>
Specify the vgdb prefix to use by callgrind_control.
callgrind_control internally uses vgdb to find and control the
active Callgrind runs. If the --vgdb-prefix option was used for
launching valgrind, then the same option must be given to
callgrind_control.
