CALLGRIND CONTROL(1) callgrind_control 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.
