shinyscorpion/wobserver

Wobserver is a web-based monitoring and metrics interface for Erlang/OTP systems, providing real-time visibility into system health and application state. It aggregates data on CPU, memory, processes, and schedulers, exposing this information through a dynamic web dashboard and a Prometheus-compatible API. The system supports distributed monitoring by connecting to remote nodes and offers extensibility through custom pages and metrics.

Users can now export metrics in Prometheus format. A new \Wobserver.Util.Metrics.Formatter\ module provides a pluggable interface for formatting metrics, with \Wobserver.Util.Metrics.Prometheus\ added as the default formatter. This allows users to view and scrape metrics using Prometheus-compatible output.

Users can now access detailed system information including architecture, CPU, and Erlang/OTP versions via the new Wobserver.System.Info module. Memory usage across categories like atom, binary, code, ETS, and processes is available through Wobserver.System.Memory. The Wobserver.System.Scheduler module provides per-scheduler utilization metrics, while Wobserver.System.Statistics exposes system uptime, process counts, and I/O statistics. These additions expand the observability of the host system within the Wobserver tool.

Added Chart.js (version 1.0.2) and Treant.js to the project's external JavaScript dependencies, enabling the use of charting and tree diagram visualizations in the application.

Two new Mix tasks have been introduced to streamline development and quality assurance. The \analyze\ task runs static analysis tools (Credo, Dialyzer, and code coverage checks) and exits if errors are found. The \build\ task automates the full build process, which now includes baking web assets (HTML, CSS, JS, and LICENSE) into a generated \Wobserver.Assets\ module, alongside compilation, documentation, and packaging steps.

Added Wobserver.Util.Node.Discovery to support discovering other nodes via DNS or custom functions, and introduced Wobserver.Util.Node.Remote to handle metrics, API calls, and WebSocket connections to remote nodes.

Added new utility modules to the Wobserver library: Wobserver.Allocator for listing memory allocator details, Wobserver.Util.Application for listing running applications and their hierarchy, Wobserver.Util.Process for detailed process information and summaries, Wobserver.Port for port status and links, Wobserver.Table for ETS table information and data, and Wobserver.Util.Metrics for managing custom metrics and generators. These modules provide the underlying data collection and formatting logic for the Wobserver dashboard.

Added the initial configuration file for the Wobserver application, setting up the Mix.Config module and defining the 'assets' configuration key.

The repository was initialized with the core project files, including the Elixir build configuration (mix.exs), a Travis CI build script (.travis.yml) for automated testing, and a CHANGELOG.md tracking version history. The project also includes a README.md with usage and installation instructions, a coveralls.json for code coverage settings, and a .gitignore file to exclude generated assets and build artifacts.

The \wobserver\ library is introduced as a new component providing a web-based interface for system metrics, monitoring, and observer tools. It includes a configurable HTTP port (defaulting to 4001) and supports two startup modes: \:standalone\ (launches a Cowboy server) and \:plug\ (returns the metric storage PID for integration into existing applications). The release adds a \Page\ system for registering and managing custom web pages and API routes, alongside a \System\ module that aggregates architecture, CPU, memory, and scheduler utilization data. An \about\ endpoint exposes version, license, and link information for the library.

The project now includes a Gulp-based build system that automates the compilation of CSS (via Sass and Autoprefixer), JavaScript (via Browserify, Babel, and Uglify), and HTML (via htmlmin). The configuration file defines separate tasks for development and production builds, with source maps enabled for debugging. A watch task is also configured to monitor source files and trigger the appropriate build tasks automatically.

Adds new modules to handle WebSocket connections and remote node proxying. The \Client\ module implements the core WebSocket command handling (e.g., :hello, :ping, :system, :about, :application, :process, :ports, :allocators, :table, :custom). A \ClientProxy\ module is added to proxy WebSocket requests to remote nodes. A \ClientSocket\ module provides the low-level WebSocket handler and callback interface. Additionally, a \Security\ module is introduced to handle basic WebSocket authentication via cookies, with support for configurable security modules.

lib/wobserver/web · high confidence

The web interface now establishes a persistent WebSocket connection to the backend for live data updates, with an automatic fallback to a JSON API if the WebSocket connection fails. This change introduces new JavaScript modules (Wobserver, WobserverClient, WobserverApiFallback) that handle connection state, reconnection logic, and message routing, enabling the UI to display real-time system metrics, process details, and charts with reduced latency compared to the previous polling or static rendering approach.

Added a new set of SCSS files in src/css/lib to define styles for buttons, menus, content areas, footers, graphs, popups, and tables. This includes a theme configuration with specific color palettes (e.g., \#58229a for primary), typography settings, and layout rules for interactive elements like selection popups and process charts.

The interface now includes new modules for displaying process details, table data, and dynamic charts. Process details show metadata, memory usage, and state in a popup. Table details display row data in a popup, including an empty state message when no data is present. A new chart module supports real-time line charts with timestamped data updates. Additionally, node selection allows users to switch between remote nodes, and process names are displayed without the 'Elixir.' prefix.

The web router has been restructured into distinct modules: a new API router providing endpoints for nodes, applications, processes, ports, and custom pages; a metrics router exposing system and node performance data; a static router serving the frontend assets (HTML, CSS, JS) with configurable security authentication; and a system router for detailed system information. A shared base module and helper utilities were added to support these changes.

The HTML entry point for the Wobserver web application has been updated to include mobile-specific meta tags. These additions, such as 'apple-mobile-web-app-capable' and 'theme-color', improve the user experience on mobile devices by enabling full-screen app-like behavior and customizing the browser's status bar color.

Added new SCSS files to style the web interface. The new \_chart.scss file defines styles for a chart component, including layout, canvas margins, and a legend with inline-block list items and colored indicators. The new main.scss file imports the chart styles and adds styling for an 'about' page section, specifically formatting tables with bold headers and a colon suffix.

Added router tests for API, root, metrics, and 404 handling; Added test coverage for Wobserver core functionality; Added test coverage for system info, memory, scheduler, and statistics modules; Added tests for Wobserver application, page, and system modules; Added tests for node discovery and remote node interactions; Added tests for the Wobserver web router components; Added tests for the new metrics formatting and Prometheus integration; Added unit tests for Wobserver utility modules.

The project is initialized with \mix.exs\ and \mix.lock\ defining Elixir dependencies (including Cowboy, HTTPoison, and Plag) and a \package.json\ establishing Node.js build tools (Gulp, Babel, etc.) for the web component. This establishes the foundational build and runtime requirements for the Wobserver application.
