This is how no-code AWS Lambda monitoring was developed as a result of addressing the tedious process of manual code instrumentation, using Amazon CloudWatch and Sentry through an automated instrumentation approach with AWS CloudFormation stack and Kinesis Data Firehose. The initial prototype had limitations such as not grouping logs into issues or displaying stack traces like Sentry. Instead, it utilized AWS Lambda Extensions to instrument functions, allowing real-time tracing, formatted stack traces, in-context environment variables, and customizable sample rates. Although there were minor downsides like requiring a specific SDK for every programming language, the outcome was a user-friendly UI that enabled easy auto-instrumentation of AWS Lambda functions with benefits such as increased developer adoption and recognition from AWS.
