OpenTelemetry Collector configurations are YAML files. There's no schema, no type system, and no IDE that will tell you that tail_smapling isn't a real processor. You find out when your pipeline goes dark and someone starts paging the on-call.

The collector ships with otelcol validate, which catches syntax errors and fails on unknown component types. That covers a slice of the problem. It won't tell you that your send_batch_max_size is smaller than your send_batch_size, that your memory limiter is effectively disabled, or that you've hardcoded an API key in plain text.
