TL;DR

The OpenTelemetry Collector is a vendor-agnostic proxy between your apps and their observability backends, with a receivers → processors → exporters pipeline for metrics, traces, and logs. It decouples application code from backend choices, batches and retries to cut network cost, lets you do central filtering, attribute enrichment, and tail-based sampling (keep all errors and slow traces, sample the rest), and can be deployed as a per-node DaemonSet agent or a centralized gateway.
