 ### OpenTelemetry Protocol (OTLP)
 
-Configure goose to export traces, metrics, and logs to any
-[OpenTelemetry](https://opentelemetry.io/docs/) compatible platform.
-When configured, goose exports telemetry asynchronously and flushes on exit.
+Configure goose to export traces and metrics to any OTLP-compatible observability platform. 
+OTLP is the standard protocol for sending telemetry collected by [OpenTelemetry](https://opentelemetry.io/docs/). When configured, goose exports telemetry asynchronously and flushes on exit.
 
-goose respects standard [OTel SDK environment variables][otel-env]. The
-simplest way to enable export is to set a collector endpoint:
-
-```bash
-export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4318"
-```
-
-This enables OTLP export for all signals (traces, metrics, logs). You can
-control each signal independently with `OTEL_{SIGNAL}_EXPORTER` where signal
-is `TRACES`, `METRICS`, or `LOGS`:
-
-| Variable pattern | Purpose | Values |
-|---|---|---|
-| `OTEL_EXPORTER_OTLP_ENDPOINT` | Base OTLP endpoint (applies `/v1/traces`, etc.) | URL |
-| `OTEL_EXPORTER_OTLP_{SIGNAL}_ENDPOINT` | Override endpoint for a specific signal | URL |
-| `OTEL_{SIGNAL}_EXPORTER` | Exporter type per signal | `otlp`, `console`, `none` |
-| `OTEL_SDK_DISABLED` | Disable all OTel export | `true` |
-
-Additional variables like `OTEL_SERVICE_NAME`, `OTEL_RESOURCE_ATTRIBUTES`,
-and `OTEL_EXPORTER_OTLP_TIMEOUT` are also supported.
-See the [OTel environment variable spec][otel-env] for the full list.
-
-**Examples:**
+| Variable | Purpose | Values | Default |
+|----------|---------|--------|---------|
+| `OTEL_EXPORTER_OTLP_ENDPOINT` | OTLP endpoint URL | URL (e.g., `http://localhost:4318`) | None |
+| `OTEL_EXPORTER_OTLP_TIMEOUT` | Export timeout in milliseconds | Integer (ms) | `10000` |
+
+**When to use OTLP:**
+- Diagnosing slow tool execution or LLM response times
+- Understanding intermittent failures across multiple sessions
+- Monitoring goose performance in production or CI/CD environments
+- Tracking usage patterns, costs, and resource consumption over time
+- Setting up alerts for performance degradation or high error rates
+
+**Example:**
 ```bash
-# Export everything to a local collector
 export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4318"
-
-# Export only traces, disable metrics and logs
-export OTEL_TRACES_EXPORTER="otlp"
-export OTEL_METRICS_EXPORTER="none"
-export OTEL_LOGS_EXPORTER="none"
-export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4318"
-
-# Debug traces to console (no collector needed)
-export OTEL_TRACES_EXPORTER="console"
+export OTEL_EXPORTER_OTLP_TIMEOUT=10000
 ```
