How Mastodon Runs OpenTelemetry Collectors in Production

Mastodon, a decentralized social media platform, successfully utilizes the OpenTelemetry Collector in production with a remarkably small operations team. They prioritize simplicity and operator freedom by allowing server administrators to choose how (or if) telemetry is collected, while ensuring data adheres to OpenTelemetry standards. Their architecture employs a single Collector per Kubernetes namespace, managed via the OpenTelemetry Operator and Argo CD, proving highly reliable and requiring minimal resource overhead thanks to strategic tail-based sampling.
