Whitepaper: AWS Lambda@Edge Logging to OpenObserve

by Dinis Cruz and ChatGPT Deep Research, 22-Feb-2025

1. Introduction

Overview: This whitepaper describes an architecture for capturing Amazon CloudFront requests using AWS Lambda@Edge and forwarding the logs to OpenObserve for centralized analysis. We integrate CloudFront (as the content delivery network) with a logging Lambda@Edge function that sends request details to OpenObserve, an open-source observability platform. This approach provides near real-time visibility into CDN traffic without waiting for standard CloudFront access logs (which can have delays of up to 24 hours (amazon web services - How to capture lambda @edge requests to kinesis? - Stack Overflow)). OpenObserve’s analytics engine allows us to search and visualize these logs with custom dashboards and real-time alerts ([Monitoring CloudFront Access Logs with K

Code Formatting Philosophy and Principles

Core Principles

1. Visual Pattern Recognition

The human brain excels at pattern recognition. This formatting prioritizes creating clear visual patterns that make code structure immediately apparent:

• Aligned equals signs create vertical lanes that guide the eye
• Consistent comma placement creates predictable rhythm
• Grouped imports with aligned elements form distinct visual blocks

"Creating a 'Print-friendly' version of a LinkedIn post that can be shared as a PDF or PNG" - How hard could it be, right?

TL;DR: Use the JavaScript code from this GIST: https://gist.github.com/DinisCruz/d5e4bb4d8a6dcd7b25e31d160c747f1e

Unless I'm missing something very obvious, there isn't an easy way to create a PDF or a PNG image from a LinkedIn post (I need posts in this format so that I can easily share them on WhatsApp, Discord, or Slack).

As an example, I wanted to share the daily poem that I posted today (see https://www.linkedin.com/posts/diniscruz_here-is-a-poem-for-the-7th-of-march-2024-activity-7171459601492602880-Tkzs) with my family, which includes some members who are not on LinkedIn.

What I wanted was to create something like what you can see in pic2, i.e., a reasonably formatted pdf/png that allows for the easy reading of the post's content (and images).
