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 using DTrace with stackcollapse.pl, +# and other tools using the stackcollapse variants. +# +# 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 output 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".
