CALLGRIND CONTROL(1) Release 3.9.0 CALLGRIND CONTROL(1)NAMEcallgrind_control - observe and control programs being run by Callgrind
SYNOPSIScallgrind_control [options] [pid|program-name...]
DESCRIPTIONcallgrind_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
Show a short description, usage, and summary of options.
Show version of callgrind_control.
Show also the working directory, in addition to the brief
information given by default.
Show statistics information about active Callgrind runs.
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
-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.
Zero all event counters.
Force a Callgrind run to be terminated.
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.
Specify the startup directory of an active Callgrind run. On some
systems, active Callgrind runs can not be detected. To be able to
control these, the failed auto-detection can be worked around by
specifying the directory where a Callgrind run was started.
