CALLGRIND CONTROL(1)             Release 3.8.0            CALLGRIND CONTROL(1)



NAME
       callgrind_control - observe and control programs being run by Callgrind

SYNOPSIS
       callgrind_control [options] [pid|program-name...]

DESCRIPTION
       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.

OPTIONS
       -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.

       -w=<dir>
           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.
