uftrace - Function graph tracer for userspace
uftrace [record|replay|live|report|info|dump|recv|graph|script|tui] [options] COMMAND [command-options]
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 --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, 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 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.
