stackcollapse-ghc: Program to fold GHC prof files into flamegraph input
Program to fold GHC prof files into flamegraph input The reasons why this package exists despite other packages with similar functionality (not including the NIH syndrome) boil down to:
it does only one thing (stack collapsing), so it's up to the user to install flamegraph scripts, pass options etc (in my eyes it's not a limitation, on the contrary),
output control: annotations (color profiles), extending traces from a configured set of modules with the source locations or toggling qualified names,
precise ticks and/or bytes with
-p
reports,it's fast
Basic usage
Visualize ticks
If you have a detailed prof file (-P
RTS option)
stackcollapse-ghc prof_file | flamegraph.pl --title 'Example' --subtitle 'Time' --countname ticks > path_to_svg
If you have a standard prof file (-p
RTS option)
stackcollapse-ghc -p prof_file | flamegraph.pl --title 'Example' --subtitle 'Time' --countname ticks > path_to_svg
Visualize allocations
If you have a detailed prof file (-P
RTS option)
stackcollapse-ghc --alloc prof_file | flamegraph.pl --title 'Example' --subtitle 'Bytes allocated' --countname bytes > path_to_svg
If you have a standard prof file (-p
RTS option)
stackcollapse-ghc --alloc -p prof_file | flamegraph.pl --title 'Example' --subtitle 'Bytes allocated' --countname bytes > path_to_svg
