support accordingly.

Team and repository tags



A visualization utility to help analyze the performance of DevStack setup and Tempest executions. This repository can be cloned and built to use Stackviz with local run data. Stackviz is currently in the process of being implemented upstream (see Roadmap and Planning). To use Stackviz with upstream gate runs, please see the server deployment project at:


Installation - Frontend

Installation of the frontend requires Node.js and Gulp. On Ubuntu:

sudo apt-get install nodejs
sudo apt-get install npm
sudo npm install -g gulp

Then, install the Node modules by running, from the project directory:

npm install

Installation - Processing

The data processor is a small Python module located in the same source tree. To install, run:

sudo pip install .


Usage - Development

A development server can be run as follows:

gulp dev

This will open a web browser and reload code automatically as it changes on the filesystem.

If you have subunit and dstat logs, you can create a config.json to display your runs:

stackviz-export -f <path/to/subunit> --dstat <path/to/dstat> app/data/

During gulp dev, files written to app/data/ will be automatically synchronized with the browser. Note that these files will not be copied to build/ during gulp prod, but you can copy them manually using gulp data.

Usage - Production

The production application can be build using:

gulp prod

This will automatically build portable html/javascript and python utilities into dist/stackviz-VERSION.tar.gz.

You should probably install this into a virtualenv on the target system:

virtualenv stackviz
./virtualenv/bin/pip install /path/to/stackviz-VERSION.tar.gz
# to run stackviz export

Note the required html will be placed in virtualenv/share/stackviz-html as a data-file (or elsewhere, if installed as a system package; this may vary on distributions). This can be moved as required. Note that all files in there are not required:

  • Directory structure (js/, css/, fonts/, images/): required.
  • Static resources (fonts/, images/): required.
  • Core files (index.html, js/main.js, css/main.css): required unless gzipped versions are used.
  • Gzipped versions of core files (*.gz): not required, but preferred. Use instead of plain core files to save on disk usage and bandwidth.
  • Source maps (js/, js/ only required for debugging purposes.

Data should be written to stackviz-html/data/ using stackviz-export like above.


  • Python tests: tox -e py36
  • JavaScript unit tests: gulp unit
  • JavaScript E2E tests: gulp e2e
