How Cloudflare instruments services using Workers Analytics Engine

Cloudflare has introduced Workers Analytics Engine, a new tool that enables developers and product teams to build time series analytics about anything, with high dimensionality, high cardinality, and effortless scaling. The Analytics Engine SQL API is used by the company itself to monitor its own API, find bugs, and prioritize new product features. It allows users to generate events from Workers with just a few lines of code and query these events using GraphQL or SQL API for useful insights about business or technology stack. Since its open beta release in September, new features have been added based on developer feedback. The Analytics Engine is designed to handle high-cardinality data and can be used with any data visualization tool like Grafana. It currently offers free 90-day retention for users.
