Ultimate Guide to Node.js Monitoring Dashboard with Watchlog – Real-Time Performance Tracking

Why Monitor a Node.js Application?

Monitoring a Node.js application with Watchlog helps you:

• Detect Performance Issues: Identify slow API responses, memory leaks, and CPU spikes.
• Ensure Stability: Prevent crashes by monitoring event loop delays and garbage collection.
• Optimize Resource Usage: Track CPU, RAM, and network activity.
• Improve User Experience: Ensure low-latency responses and prevent downtime.

Key Metrics to Monitor with Watchlog

When using Watchlog for Node.js monitoring, focus on the following key metrics:

• CPU Usage - Helps detect resource-intensive operations.
• Memory Usage - Monitors memory leaks and garbage collection efficiency.
• Event Loop Lag - Measures if the event loop is getting blocked.
• Response Time - Tracks how long API requests take to resolve.
• Active Connections - Shows the number of concurrent users.
• Error Logs - Captures runtime errors and uncaught exceptions.
• Database Queries - Monitors query performance and failures.
• Network Traffic - Analyzes request and response sizes.

Getting Started with Watchlog for Node.js Monitoring

Step 1: Install the Watchlog Agent

For Ubuntu Server, you can install the Watchlog Agent with a single command:

sudo apiKey="your-api-key" server='your-server' bash -c "$(curl -L https://watchlog.io/ubuntu/watchlog-script.sh)"

Replace your-api-key and your-server with your actual Watchlog API key and Server from the Watchlog Dashboard.

Once installed, you can monitor your server's CPU, memory, connections, disk, and latency directly from Watchlog.

Step 2: Install the Watchlog NPM Package

After installing the Watchlog Agent, install the Node.js package to send custom metrics:

npm install watchlog-metric

Step 3: Send Custom Events

Use the Watchlog Metric package in your Node.js application to track custom events:

const watchlog = require("watchlog-metric");


// Send Metric: Increments a stat by a value (default is 1)
watchlog.increment("Your_metric");


// Send Metric: Increments a stat by a specific value (e.g., 75)
watchlog.increment("Your_metric", 75);
