7## Install
8npm install @azure/monitor-opentelemetry

10## Quick Start
11```typescript
12import { useAzureMonitor } from "@azure/monitor-opentelemetry";
13useAzureMonitor({
14  azureMonitorExporterOptions: {
15    connectionString: process.env.APPLICATIONINSIGHTS_CONNECTION_STRING
16  }
17});
18```

20## Best Practices
21- Call useAzureMonitor() first — before importing other modules
22- Use ESM loader for ESM projects — `--import @azure/monitor-opentelemetry/loader`
23- Enable offline storage for reliable telemetry in disconnected scenarios
24- Set sampling ratio for high-traffic applications
25- Add custom dimensions — use span processors for enrichment
26- Graceful shutdown — call shutdownAzureMonitor() to flush telemetry
