StackViz: Angular

A visualization utility to help analyze the performance of DevStack setup and Tempest executions.

Installation

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

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

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

npm 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.

Usage - Production

The production application can be build using:

gulp prod

The result will be written to ./build and should be appropriate for distribution. Note that all files 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/main.js.map, js/main.js.map.gz): only required for debugging purposes.

Roadmap

• Project split: All server-side components will be removed, and replaced with specialized data transformation tools.

  - Data sources and processing: stackviz Python project, with

  stackviz-export used to generate JSON data files and configuration.

  • Web interface:
    • Will remain in this namespace (openstack-qa/stackviz).
    • Will decouple data processing from build process, allowing for distribution to nodes as a prebuilt static site.
    • Data sources will be configured in in a config.json.
    • Will support local and remote sources via REST/JSONP (pending API spec).

• Angular conversion: current codebase will be rewritten to use Angular.
