OpenTelemetry instrumentation, Jaeger/Tempo backends, trace analysis, and observability patterns for microservices.

General

What this skill does


# Distributed Tracing

Trace requests across microservices with OpenTelemetry.

## Quick Start — Jaeger

```bash
# Run Jaeger all-in-one
docker run -d --name jaeger \
  -p 16686:16686 \
  -p 4317:4317 \
  -p 4318:4318 \
  jaegertracing/jaeger:latest

# UI at http://localhost:16686
```

## OpenTelemetry (Node.js)

```bash
# Install
npm install @opentelemetry/sdk-node @opentelemetry/auto-instrumentations-node @opentelemetry/exporter-trace-otlp-grpc
```

```javascript
// tracing.js — load before app code
const { NodeSDK } = require('@opentelemetry/sdk-node');
const { getNodeAutoInstrumentations } = require('@opentelemetry/auto-instrumentations-node');
const { OTLPTraceExporter } = require('@opentelemetry/exporter-trace-otlp-grpc');

const sdk = new NodeSDK({
  traceExporter: new OTLPTraceExporter({ url: 'http://localhost:4317' }),
  instrumentations: [getNodeAutoInstrumentations()],
  serviceName: 'my-service',
});
sdk.start();
```

```bash
# Run with tracing
node -r ./tracing.js app.js
```

## OpenTelemetry (Python)

```bash
# Install
pip install opentelemetry-sdk opentelemetry-exporter-otlp opentelemetry-instrumentation

# Auto-instrument
opentelemetry-instrument --service_name my-service --exporter_otlp_endpoint http://localhost:4317 python app.py
```

## Query Traces

```bash
# Jaeger API — find traces by service
curl -s "http://localhost:16686/api/traces?service=my-service&limit=10" | jq '.data[] | {traceID, spans: (.spans | length), duration: .spans[0].duration}'

# Find slow traces (>1s)
curl -s "http://localhost:16686/api/traces?service=my-service&minDuration=1000000" | jq '.data | length'

# Traces with errors
curl -s "http://localhost:16686/api/traces?service=my-service&tags=%7B%22error%22%3A%22true%22%7D" | jq '.data | length'
```

## Custom Spans

```javascript
const { trace } = require('@opentelemetry/api');
const tracer = trace.getTracer('my-module');

async function processOrder(orderId) {
  return tracer.startActiveSpan('process-order', async (span) => {
    span.setAttribute('order.id', orderId);
    try {
      const result = await db.getOrder(orderId);
      span.setAttribute('order.total', result.total);
      return result;
    } catch (error) {
      span.recordException(error);
      span.setStatus({ code: 2, message: error.message });
      throw error;
    } finally {
      span.end();
    }
  });
}
```

## What to Look For

- **Long spans** — bottleneck identification
- **Error spans** — where requests fail
- **Fan-out** — one request triggering many downstream calls (N+1 at service level)
- **Missing spans** — services not instrumented
- **Trace gaps** — context not propagated between services

## Notes

- Auto-instrumentation covers HTTP, database, and message queue calls automatically.
- Propagate trace context via headers (`traceparent`) between services.
- Sample in production — tracing every request is expensive. Start with 1-10%.
- Jaeger is good for development. Grafana Tempo is better for production (integrates with Grafana dashboards).
- Traces + metrics + logs = full observability. Correlate them with trace IDs.

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
