Otel Collector Config

Use when authoring, debugging, or reviewing an OpenTelemetry Collector (otelcol) configuration — defining receivers/processors/exporters/connectors, wiring service pipelines, choosing between the core and contrib distributions, or exporting to OTLP/Prometheus/Loki/Tempo/Mimir. Also use when a Collector starts but no data arrives, a component is rejected at startup, or metrics lack expected labels. Triggers on "otelcol", "otel collector config", "collector pipeline", "receivers/processors/exporters", "memory_limiter", "otlp exporter", "prometheusremotewrite", "spanmetrics", "tail_sampling".

# OpenTelemetry Collector config — doctor

Generate correct configs from a plain-English description, and diagnose broken
ones. The Collector is a small set of concepts with a lot of sharp edges; this
skill encodes the edges so the output validates on the first try.

## Mental model (get this right and everything follows)

A Collector config has four component blocks plus a `service` block that wires
them:

```
receivers:   # where data comes IN  (otlp, prometheus, hostmetrics, filelog, kafka…)
processors:  # what happens in the MIDDLE, in order (memory_limiter, batch, transform…)
exporters:   # where data goes OUT  (otlp, otlphttp, debug, prometheus, prometheusremotewrite…)
connectors:  # bridge one pipeline's OUTPUT into another's INPUT (spanmetrics, routing…)
extensions:  # collector-level features, not in the data path (health_check, pprof, zpages…)

service:
  extensions: [health_check]
  pipelines:
    traces:  { receivers: [...], processors: [...], exporters: [...] }
    metrics: { receivers: [...], processors: [...], exporters: [...] }
    logs:    { receivers: [...], processors: [...], exporters: [...] }
  telemetry: { ... }   # the Collector's OWN logs/metrics
```

**The #1 rule everyone violates:** defining a component under `receivers:` /
`processors:` / `exporters:` does **nothing** on its own. A component only runs
if it is referenced inside a `service.pipelines.<signal>` list. A config can be
