We're excited to announce the release of Watt Admin, an open-source developer monitoring and administration tool for Platformatic applications. This powerful dashboard gives developers real-time visibility into their Node.js services, making monitoring performance, troubleshooting issues, and managing Watt easier than ever.

Watt Admin is a single command away from your Watt application: npx wattpm admin.

Let’s break down the key features:

  • Real-Time Performance Metrics

  • Logging

  • Runtime selection

  • Service control

Real-Time Performance Metrics

Watt Admin provides detailed real-time metrics for your Platformatic applications:

  • Memory Usage Monitoring: Track RSS, heap usage, new space, and old space memory allocation with visual charts

  • CPU & Event Loop Utilization: Monitor CPU usage and event loop utilization to identify performance bottlenecks

  • Latency Tracking: View P90, P95, and P99 latency metrics to ensure optimal response times

  • Request Rate Analysis: Track requests per second (RPS) to understand traffic patterns

Comprehensive Logging

Stay informed with advanced logging capabilities:

  • Centralized Log Viewer: View logs from all services in a single interface

  • Log Filtering: Filter logs by service or log level to find relevant information quickly

  • Pretty or Raw View: Toggle between formatted and raw JSON log views

  • Log Export: Save logs for offline analysis or sharing

Service Management

Gain full control over your Platformatic services:

  • Service Overview: View all running services with their current status

  • Service-Level Metrics: Drill down into metrics for individual services

  • Service Comparison: Compare metrics between services and aggregated data

  • Service Restart: Restart services directly from the dashboard

CLI Integration

Watt Admin includes a powerful CLI tool that:

  • Discovers Runtimes: Automatically finds all available Platformatic runtimes

  • Interactive Selection: Choose between multiple runtimes with an interactive menu

  • Runtime Information: View detailed information about selected runtimes

Getting Started

Getting started with Watt Admin is simple. First, we can start a simple application managed by Watt that is composed of a Next.js, Node.js and Fastify services, as well as our Composer:

git clone https://github.com/platformatic/composer-next-node-fastify
cd composer-next-node-fastify
npm install
npm run build
npm start

You can also use it on your own Watt application! Then, starting Watt Admin is as simple as:

npx wattpm admin

You can then open localhost:4042 or click on the URL that is printed on the console.

Watt Admin looks like:
