How to Monitor a Node.js Application with Watchlog

Step 1: Install the Watchlog Agent

The first step in monitoring your Node.js application is to install the Watchlog agent on your server. This agent is responsible for collecting system metrics and sending them to the Watchlog dashboard for visualization and analysis.

Watchlog Agent Installation Guide:

1. Download the Watchlog agent installation script.
2. Run the installation command for your operating system (e.g., Ubuntu or CentOS).
3. Start the agent service to begin collecting data.

Step 2: Integrate Watchlog with Your Node.js Application

After setting up the Watchlog agent, you need to connect your Node.js application to Watchlog to send custom metrics.

Steps to Integrate:

Install the Watchlog metrics package in your Node.js project by running the following command:

npm install watchlog-metric

Import and configure the package in your application code:

const watchlog = require("watchlog-metric")

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

watchlog.increment("Your_metric" , 75)

Start sending metrics such as request rates, error counts, response times, or any other application-specific data.

Step 3: Monitor Metrics in the Watchlog Dashboard

Once the agent is installed and your application is configured to send metrics, you can monitor them in the Watchlog Dashboard.

What You Can Monitor:

• Application Performance: View metrics like request latency, error rates, and throughput.
• System Health: Monitor server metrics, including CPU usage, memory utilization, disk I/O, and network activity.
• Custom Metrics: Visualize and analyze the specific metrics you define in your Node.js application.

Benefits of the Watchlog Dashboard:

• Real-Time Monitoring: Gain instant insights into your application's performance.
• Alerts and Notifications: Get notified via email or webhooks if metrics exceed thresholds.
• Custom Visualizations: Tailor dashboards to display the metrics that matter most to your team.
