Daily Operations +```bash +# Check system health +telecom-cli health + +# Review new subscribers +telecom-cli subscribers list --status new --enhanced + +# Check service status +telecom-cli services list --enhanced + +# Review billing +telecom-cli billing invoices --unpaid +``` + +#### 2. Troubleshooting +```bash +# Check service logs +telecom-cli monitoring logs --service api-server --tail 100 + +# View metrics +telecom-cli monitoring metrics --service api-server + +# Check system resources +telecom-cli monitoring resources +``` + +#### 3. Deployment +```bash +# Deploy to staging +telecom-cli deploy --environment staging + +# Monitor deployment +telecom-cli deploy status --environment staging + +# Check health after deployment +telecom-cli health --environment staging +``` + +### Advanced Usage + +#### Batch Operations +```bash +# Export subscribers to CSV +telecom-cli subscribers list --format csv > subscribers.csv + +# Bulk update subscribers +while read line; do + telecom-cli subscribers update $line +done < updates.txt +``` + +#### Automation Scripts +```bash +#!/bin/bash +# health-check.sh + +# Check system
