CALLGRIND CONTROL(1) callgrind_control 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. --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.
