**Summary:** Agent Starter Pack includes production-grade observability with zero config. Cloud Trace, Log Analytics, and BigQuery integration out of the box.

**Day 5 of Google's Advent of Agents**

Your agent is deployed. But what's it actually doing?

Agent Starter Pack now includes production observability. Zero config required.

Full production-grade observability that enterprises need, built-in from day one.

**Two levels of observability, automatically configured:**

**1. Agent Telemetry**
- Cloud Trace captures every execution
- LLM calls with latency breakdown
- Tool execution timing
- Full conversation flow visibility

**2. Prompt-Response Logging (Auto-enabled)**
- Full E2E journey provisioned via Terraform
- Log Analytics + Log Buckets with custom retention
- BigQuery Delta Lake with custom views for easy querying
- No sensitive data in logs - all content written to GCS

**Deploy with one command:**

```bash
uvx agent-starter-pack create my-agent -a adk_base -d agent_engine
make deploy
```

Most teams spend weeks setting up observability infrastructure. You get it in minutes. No configuration. No setup. No custom instrumentation. Just deploy and start monitoring.

## Code & Commands

```bash
uvx agent-starter-pack create my-agent -a adk_base -d agent_engine
make deploy
```
