Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

stack-convert

stackconvert is a CLI tool to convert perf record stacks to a JSON hierarchical data structure that can be consumed by d3-flame-graph.

Getting Started

stackconvert is available from npm and can be installed using the following command.

$ npm install stack-convert -g

Once the tool is installed, it can be used in the CLI.

$ stackconvert perf.data > perf.json

Where:

perf.data is the output file from perf record you want to convert

Options

Collapsed/Folded Stacks

The tool can also be used with collapsed/folded stacks generated by @brendangregg, stackcollapse-perf.pl script.

$ stackconvert --folded perf.data-folded > perf.json

Live Flame Graphs

The tool can be used to generate input for live flame graphs by adding a time dimension to the output. In this case, the input file must be the multiline perf record output, not the folded/collapsed stacks, since those do not contain timestamps.

$ stackconvert --live perf.data > perf.json

Examples

Input and Output examples can be found in the examples directory.
