# flamegraph.pl flame stack grapher.
|
|
|
|
|
|
#
|
|
|
|
|
|
# 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).

# HISTORY
|
|
|
|
|
|
#
|
|
|
|
|
|
# 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:
