+# goose — OpenTelemetry to Last9
+
+Send goose (Block's open-source AI coding agent) telemetry — traces, metrics, and logs — to Last9 via OpenTelemetry.
+
+goose uses **standard `OTEL_*` env vars** (no custom prefix) and emits all three signal types out of the box. Default temporality is **cumulative**, so it ingests cleanly into Last9 without conversion.
+
+## Prerequisites
+
+- A Last9 account ([app.last9.io](https://app.last9.io))
+- OTLP credentials from **Integrations → OpenTelemetry** in the Last9 dashboard
+- goose installed — `brew install block-goose-cli` or follow [install docs](https://block.github.io/goose/docs/getting-started/installation)
+
+## Option 1 — Direct Export to Last9 (no Collector)
+
+Add the following to your shell profile (`~/.zshrc`, `~/.bashrc`, etc.):
+
+```bash
+export OTEL_EXPORTER_OTLP_ENDPOINT="https://<your-last9-otlp-endpoint>"
+export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Basic <your-last9-auth-token>"
+export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
+export OTEL_SERVICE_NAME=goose
+export OTEL_RESOURCE_ATTRIBUTES="deployment.environment=local"
+```
+
+Reload, then run goose:
+
+```bash
+source ~/.zshrc
+goose session
+```
+
+Telemetry flushes:
+- **Traces** — on span end
+- **Metrics** — every 60 seconds (default OTel SDK)
+- **Logs** — on log emission (or batched briefly)
+
+## Option 2 — Local OpenTelemetry Collector
+
+Useful for batching, retries, or fan-out to multiple backends.
+
+1. Copy `.env.example` to `.env` and fill in your Last9 credentials:
+
+   ```bash
+   cp .env.example .env
+   ```
+
+2. Start the collector:
+
+   ```bash
+   docker compose up -d
+   ```
+
+3. Point goose at the local collector:
+
+   ```bash
+   export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4317"
+   export OTEL_EXPORTER_OTLP_PROTOCOL=grpc
+   export OTEL_SERVICE_NAME=goose
+   ```
+
+4. Run goose normally.
+
+## Configuration Reference
+
+goose honors the standard [OpenTelemetry SDK environment variables](https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/).
+
+### Core
+
+| Variable | Purpose |
+|---|---|
+| `OTEL_EXPORTER_OTLP_ENDPOINT` | Base OTLP endpoint (SDK appends `/v1/traces`, etc.) |
+| `OTEL_EXPORTER_OTLP_HEADERS` | `key=value` comma-separated auth headers |
+| `OTEL_EXPORTER_OTLP_PROTOCOL` | `grpc`, `http/protobuf`, or `http/json` |
+| `OTEL_SERVICE_NAME` | Service name override (default: `goose`) |
+| `OTEL_RESOURCE_ATTRIBUTES` | Comma-separated `key=value` resource tags |
+| `OTEL_SDK_DISABLED` | Set `true` to disable all OTel export |
+
+### Per-signal control
+
+| Variable | Purpose |
+|---|---|
+| `OTEL_TRACES_EXPORTER` | `otlp`, `console`, `none` |
+| `OTEL_METRICS_EXPORTER` | `otlp`, `console`, `none` |
+| `OTEL_LOGS_EXPORTER` | `otlp`, `console`, `none` |
+| `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT` | Traces-only endpoint override |
+| `OTEL_EXPORTER_OTLP_METRICS_ENDPOINT` | Metrics-only endpoint override |
+| `OTEL_EXPORTER_OTLP_LOGS_ENDPOINT` | Logs-only endpoint override |
+
+### Sampling
+
+| Variable | Purpose |
+|---|---|
+| `OTEL_TRACES_SAMPLER` | `parentbased_traceidratio`, `always_on`, etc. |
+| `OTEL_TRACES_SAMPLER_ARG` | Sampling ratio (e.g. `0.1` for 10%) |
+
+### Anonymous usage data (separate from OTel)
+
+| Variable | Purpose |
+|---|---|
+| `GOOSE_TELEMETRY_ENABLED` | Enable/disable anonymous usage data collection (separate from OTel above) |
+
+`.env` variables (Collector path):
+
+| Variable | Purpose |
+|---|---|
+| `LAST9_OTLP_ENDPOINT` | Last9 OTLP endpoint (e.g. `https://otlp.last9.io`) |
+| `LAST9_OTLP_AUTH` | Last9 Basic auth header value (`Basic <base64>`) |
+
+## Verification
+
+After running a goose session for a minute:
+
+1. **Traces** — filter by `service.name = goose` in Last9 Traces Explorer. Notable spans: `reply_stream`, `dispatch_tool_call`
+2. **Metrics** — search for series with `service_name="goose"` in Metrics Explorer
+3. **Logs** — filter by `service.name = goose` in Logs Explorer
+
+## Goose Configuration File
+
+Alternative: configure via `~/.config/goose/config.yaml`:
+
+```yaml
+otel_exporter_otlp_endpoint: "https://<your-last9-otlp-endpoint>"
+otel_exporter_otlp_timeout: 30
+```
+
+Env vars take precedence over config file values.
+
+## Troubleshooting
+
+- **No data in Last9** — confirm `echo $OTEL_EXPORTER_OTLP_ENDPOINT` in the same shell where you run `goose`. Restart goose after any env var change.
+- **401 errors** — verify `OTEL_EXPORTER_OTLP_HEADERS=Authorization=Basic <token>` (key=value format, no HTTP colon syntax).
+- **High trace volume** — set `OTEL_TRACES_SAMPLER=parentbased_traceidratio` and `OTEL_TRACES_SAMPLER_ARG=0.1` to sample 10%.
+- **Service name appears as `unknown_service`** — set `OTEL_SERVICE_NAME=goose` explicitly. goose's resource builder defaults to `goose` but env var takes precedence.
