Ubuntu Manpage: uftrace - Function graph tracer for userspace

NAME

       uftrace - Function graph tracer for userspace

SYNOPSIS

       uftrace    [record|replay|live|report|info|dump|recv|graph|script]    [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).   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).

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

OPTIONS

-?, --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 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 and event. 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 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.
