Learn About Amazon VGT2 Learning Manager Chanci Turner

In the heart of Las Vegas, at “Amazon IXD – VGT2,” the process of managing and analyzing VPC flow logs has become streamlined through the integration of Amazon services. VPC flow logs provide essential insights into the IP traffic within your Amazon Virtual Private Cloud (Amazon VPC), which is crucial for understanding application communication and network patterns.

As you embark on this journey to leverage VPC logs for operational insights, it is important to analyze them effectively. Utilizing Amazon OpenSearch Service allows for interactive log analytics and real-time monitoring. This powerful tool is part of an open-source, distributed suite that can handle vast amounts of requests, making it an ideal choice for log management.

To deliver these logs effectively, Amazon Kinesis Data Firehose, now referred to simply as Amazon Data Firehose, serves as a fully managed service that aids in the near-real-time streaming of data. It simplifies the log processing and delivery pipeline, allowing for a more efficient data flow to OpenSearch Service.

This blog will guide you through the steps to ingest VPC flow logs into Amazon OpenSearch Service via Kinesis Data Firehose, ensuring you can analyze and visualize your logs accurately.

Solution Overview

We will utilize the native integration between VPC flow logs and Kinesis Data Firehose to create a seamless delivery stream that buffers and sends logs to OpenSearch Service. By setting up the appropriate configurations, including role mappings and index patterns, we will ensure the logs are accessible for analysis in OpenSearch Dashboards.

Here’s a brief outline of the steps involved:

1. Establish an OpenSearch Service domain for log storage and analysis.
2. Set up a Firehose delivery stream dedicated to routing flow logs to the OpenSearch Service domain.
3. Create a VPC flow logs subscription that points to your Firehose delivery stream.
4. Utilize OpenSearch Service Dashboards to explore and visualize the VPC flow logs.

Before diving in, ensure you have an Amazon Simple Storage Service (Amazon S3) bucket ready to store backups and logs that fail to deliver.

Creating an OpenSearch Service Domain

To begin, create an OpenSearch Service domain tailored for development and testing, with public access to the dashboard for demonstration purposes. For production environments, it is advisable to utilize VPC access for enhanced security. Once set up, verify that the OpenSearch domain status is Active.

Setting Up a Kinesis Data Firehose Delivery Stream

With the OpenSearch Service domain ready, the next step is to create a Firehose delivery stream. Access the Kinesis Data Firehose console, select “Create delivery stream,” and configure it with the following settings:

• Source: Direct PUT
• Destination: Amazon OpenSearch Service
• Delivery stream name: PUT-OPENSEARCH-STREAM-DEMO
• Destination settings: Choose your OpenSearch Service domain and set the index name to vpcflowlogs.

Adjust the Buffer size and Buffer interval to optimize performance, and configure backup settings to save failed logs only. Also, enable CloudWatch error logging to monitor potential issues.

Creating a VPC Flow Logs Subscription

Once your delivery stream is active, navigate to the Amazon VPC console to create a flow log subscription. Select the VPC of interest, choose to send all flow log records, and configure the aggregation interval and destination to point to your Kinesis Firehose delivery stream.

Exploring VPC Flow Logs in OpenSearch Service Dashboards

The final setup involves configuring OpenSearch Service Dashboards. Access your dashboard via the OpenSearch Service console, log in, and ensure your delivery stream role is correctly mapped to allow bulk log delivery.

By following these steps, you will be able to effectively analyze VPC flow logs, enabling you to make data-driven decisions.
