digitalmars.D.announce - profdump - Converts your 'trace.log' files into dot graphs
- Anton Fediushin (27/27) May 06 2017 profdump parses 'trace.log' (output of default profiler) and
profdump parses 'trace.log' (output of default profiler) and converts it to: - Plain text - More readable and user-friendly than raw trace.log - JSON - Can be used if you wanna process it with your scripts - DOT Graph - Nice and colourful graphs You can customize output: --threshold - If time spent on the function is below this threshold, it will be hidden. Takes seconds --pretty - outputs formatted JSON (default: true) --colour - sets colours of nodes. takes string[float] For example: dub run profdump -- --colour=0=gray --colour=50=red --dot trace.log graph.dot Will create 'graph.dot': Functions which takes < 50% of time will be gray Functions which takes >= 50% of time will be red Also, you should use 'dot' tool from graphviz to generate image (because .dot files just contains graph description) Check out profdump at DUB: http://code.dlang.org/packages/profdump And start an issue at GitHub: https://github.com/ohdatboi/profdump Issues: - Functions with long names (like phobos' ones) will take a lot of space on the graph. - profdump doesn't check input trace.log file. If it fails, try to delete your trace.log and generate new one. - Dunno what to do about profilers of other compilers (LDC and GDC). Is format same as in DMD? Let me know.
