1. Set Up OpenSearch Dashboard using Instaclustr
Refer to this video to create a cluster: Getting started with OpenSearch on Instaclustr

⚠️ Note: It may take a few minutes for your cluster to start running.

2. Set Up OpenSearch & Integrate Logging in Your Application

Once your cluster is running, go to the Connection Info section below your cluster details. There, you’ll find your OpenSearch username and password.
Scroll down to find the public host address and port — this is the host you'll use to set up logging in your app

Once you have all things, install below npm packages

npm install winston @opensearch-project/opensearch yarn add winston @opensearch-project/opensearch

Paste the code from this gist into logger.js file in your project.
Run your application — you should see logs printing to the console.

3. Set Up Your Index in OpenSearch

Head over to your OpenSearch Dashboard.
Navigate to Dashboard Management → Index Patterns to create and manage your index.

4. Send Logs from Your Application to OpenSearch 🚀🚀

Once the index is set up, your application logs will start flowing into OpenSearch automatically!

5. View Logs in OpenSearch Dashboards

Go to the OpenSearch Dashboard Overview page.
Click on Discover.

6. That's It — You’re All Set! 🚀🚀

Your logs should now appear in the dashboard:

That’s all you need to get started with OpenSearch logging in your Node.js application.
You can now monitor, search, and visualize logs in real time — right from your OpenSearch dashboard.
