NAME

       uftrace - Function graph tracer for userspace

SYNOPSIS

       uftrace [record|replay|live|report|info|dump|recv|graph|script|tui] [options] COMMAND [command-options]

DESCRIPTION

       The  uftrace  tool is a function tracer that traces the execution of given COMMAND at the function level.
       COMMAND should be a C or C++ executable built with compiler instrumentation  (-pg  or  -finstrument-func‐
       tions).   COMMAND  needs  to have an ELF symbol table (i.e. not be strip(1)-ed) in order for the names of
       traced functions to be available.

       The uftrace command consists of a number of sub-commands, in the manner of git(1) or perf(1).  Below is a
       short description of each sub-command.  For more detailed information, see the respective  manual  pages.
       The options in this page can be given to any sub-command also.

       For  convenience,  if no sub-command is given, uftrace acts as though the live sub-command was specified,
       which runs the record and replay sub-commands in turn.  See uftrace-live(1) for options belonging to  the
       live  sub-command.  For more detailed analysis, it is better to use uftrace-record(1) to save trace data,
       and then analyze it with other uftrace commands like  uftrace-replay(1),  uftrace-report(1),  uftrace-in‐
       fo(1), uftrace-dump(1), uftrace-script(1) or uftrace-tui(1).

SUB-COMMANDS

       record Run a given command and save trace data in a data file or directory.

       replay Print recorded function trace data with time durations.

       live   Do live tracing.  Print function trace of the given command.

       report Print various statistics and summary of the recorded trace data.

       info   Print side-band information like OS version, CPU info, command line and so on.

       dump   Print raw tracing data in the data files.

       recv   Save tracing data sent to network

       graph  Print function call graph

       script Run a script for recorded function trace

       tui    Show text user interface for graph and report

OPTIONS

       -?, --help
              Print help message and list of options with description

       -h, --help
              Print help message and list of options with description

       --usage
              Print usage string

       -V, --version
              Print program version

       -v, --verbose
              Print verbose messages.  This option increases a debug level and can be used at most 3 times.

       --debug
              Print  debug messages.  This option is same as -v/--verbose and is provided only for backward com‐
              patibility.

       --debug-domain=DOMAIN[,DOMAIN, ...]
              Limit the printing of debug messages to those belonging to one of the DOMAINs  specified.   Avail‐
              able  domains  are:  uftrace,  symbol, demangle, filter, fstack, session, kernel, mcount, dynamic,
              event, script and dwarf.  The domains can have an their own debug level optionally (preceded by  a
              colon).   For  example, -v --debug-domain=filter:2 will apply debug level of 2 to the “filter” do‐
              main and apply debug level of 1 to others.

       -d DATA, --data=DATA
              Specify name of trace data (directory).  Default is uftrace.data.

       --logfile=FILE
              Save warning and debug messages into this file instead of stderr.

       --color=VAL
              Enable or disable color on the output.  Possible values are “yes”(= “true” | “1” | “on” ),  “no”(=
              “false”  |  “0” | “off” ) and “auto”.  The “auto” value is default and turns on coloring if stdout
              is a terminal.

       --no-pager
              Do not use a pager.

       --opt-file=FILE
              Read command-line options from the FILE.
