Vector is an open source on-host performance monitoring framework which exposes hand picked high resolution system and application metrics to every engineer’s browser. Having the right metrics available on-demand and at a high resolution is key to understand how a system behaves and correctly troubleshoot performance issues.


Vector is under development and new features are added constantly. Bugs and issues are expected. We count on your support to find and report them! Use releases for stable code.

Getting Started

See the Getting Started Guide for documentation on how to get started.


Specific configuration for your environment can be set up at the following locations:

src/config.js               # app-wide configuration
src/charts/*                # set up chart widgets
src/bundles/*               # configure the high level groups
help/*                      # and the help panels for the charts

After you are set up, standard npm package.json commands can be used:

nvm use
npm install
npm run build
npm run serve

At a high level, the remaining directories contain:

src/components/*            # all of the React components that compose the page
src/components/Pollers/*    # the React components that talk to the PCP backend
processors/*                # pcp to graph data fetch and transform components


For bugs, questions and discussions please use the GitHub Issues.


Join Vector on Slack for support and discussion. If you don't have an invite yet, request one now!

You can also ask questions to other Vector users and contributors on Google Groups or Stack Overflow.


For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Vector will be maintained under the Semantic Versioning guidelines as much as possible.

Releases will be numbered with the following format:


And constructed with the following guidelines:

  • Breaking backward compatibility bumps the major (and resets the minor and patch)
  • New additions without breaking backward compatibility bumps the minor (and resets the patch)
  • Bug fixes and misc changes bumps the patch
