 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # This takes stack samples and renders a call graph, allowing hot functions
 | 
					
						
							|  |  |  |  | # and codepaths to be quickly identified.  Stack samples can be generated using
 | 
					
						
							|  |  |  |  | # tools such as DTrace, perf, SystemTap, and Instruments.
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # USAGE: ./flamegraph.pl [options] input.txt > graph.svg
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | #        grep funcA input.txt | ./flamegraph.pl [options] > graph.svg
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # Then open the resulting .svg in a web browser, for interactivity: mouse-over
 | 
					
						
							|  |  |  |  | # frames for info, click to zoom, and ctrl-F to search.
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # Options are listed in the usage message (--help).
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # The input is stack frames and sample counts formatted as single lines.  Each
 | 
					
						
							|  |  |  |  | # frame in the stack is semicolon separated, with a space and count at the end
 | 
					
						
							|  |  |  |  | # of the line.  These can be generated for Linux perf script output using
 | 
					
						
							|  |  |  |  | # stackcollapse-perf.pl, for DTrace using stackcollapse.pl, and for other tools
 | 
					
						
							|  |  |  |  | # using the other stackcollapse programs.  Example input:
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | #  swapper;start_kernel;rest_init;cpu_idle;default_idle;native_safe_halt 1
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # An optional extra column of counts can be provided to generate a differential
 | 
					
						
							|  |  |  |  | # flame graph of the counts, colored red for more, and blue for less.  This
 | 
					
						
							|  |  |  |  | # can be useful when using flame graphs for non-regression testing.
 | 
					
						
							|  |  |  |  | # See the header comment in the difffolded.pl program for instructions.
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # The input functions can optionally have annotations at the end of each
 | 
					
						
							|  |  |  |  | # function name, following a precedent by some tools (Linux perf's _[k]):
 | 
					
						
							|  |  |  |  | # 	_[k] for kernel
 | 
					
						
							|  |  |  |  | #	_[i] for inlined
 | 
					
						
							|  |  |  |  | #	_[j] for jit
 | 
					
						
							|  |  |  |  | #	_[w] for waker
 | 
					
						
							|  |  |  |  | # Some of the stackcollapse programs support adding these annotations, eg,
 | 
					
						
							|  |  |  |  | # stackcollapse-perf.pl --kernel --jit. They are used merely for colors by
 | 
					
						
							|  |  |  |  | # some palettes, eg, flamegraph.pl --color=java.
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # The output flame graph shows relative presence of functions in stack samples.
 | 
					
						
							|  |  |  |  | # The ordering on the x-axis has no meaning; since the data is samples, time
 | 
					
						
							|  |  |  |  | # order of events is not known.  The order used sorts function names
 | 
					
						
							|  |  |  |  | # alphabetically.
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # While intended to process stack samples, this can also process stack traces.
 | 
					
						
							|  |  |  |  | # For example, tracing stacks for memory allocation, or resource usage.  You
 | 
					
						
							|  |  |  |  | # can use --title to set the title to reflect the content, and --countname
 | 
					
						
							|  |  |  |  | # to change "samples" to "bytes" etc.
 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # There are a few different palettes, selectable using --color.  By default,
 | 
					
						
							|  |  |  |  | # the colors are selected at random (except for differentials).  Functions
 | 
					
						
							|  |  |  |  | # called "-" will be printed gray, which can be used for stack separators (eg,
 | 
					
						
							|  |  |  |  | # between user and kernel stacks).

 | 
					
						
							|  |  |  |  | #
 | 
					
						
							|  |  |  |  | # This was inspired by Neelakanth Nadgir's excellent function_call_graph.rb
 | 
					
						
							|  |  |  |  | # program, which visualized function entry and return trace events.  As Neel
 | 
					
						
							|  |  |  |  | # wrote: "The output displayed is inspired by Roch's CallStackAnalyzer which
 | 
					
						
							|  |  |  |  | # was in turn inspired by the work on vftrace by Jan Boerhout".  See:
