       uftrace - Function graph tracer for userspace


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


       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).   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-report(1), uftrace-info(1), uftrace-dump(1) or uftrace-replay(1).


       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


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

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

              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.

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

       --debug-domain=DOMAIN[,DOMAIN, ...]
              Limit the printing of debug messages to those  belonging  to  one  of  the  DOMAINs
              specified.   Available  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”  domain  and
              apply debug level of 1 to others.

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

              Save warning and debug messages into this file instead of stderr.

              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.

              Do not use a pager.

              Read command-line options from the FILE.
