-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d @monitoring/grafana/ml_training_dashboard.json
# 3. Reload Prometheus
curl -X POST http://localhost:9090/-/reload
# 4. Restart AlertManager
docker-compose restart alertmanager
# 5. Test Slack
curl -X POST ${SLACK_WEBHOOK_URL} \
-H "Content-Type: application/json" \
-d '{"text": "Test alert from ML Training"}'
📊 Key Dashboards
- Grafana: http://localhost:3000/d/ml-training-monitoring
- Prometheus: http://localhost:9090/graph
- AlertManager: http://localhost:9093
🔔 Alert Thresholds (Critical)
| Alert | Threshold | Action |
|---|---|---|
| GPU Memory Exhausted | >95% | Reduce batch size NOW |
| GPU Temperature High | >85°C | Check cooling |
| Training Job Stuck | No progress >1hr | Kill job, restart |
| Monthly Cost Exceeded | >$1000 | Review costs |
| S3 Storage High | >1TB | Clean old models |
💰 Cost Estimates
- S3: $0.023/GB/month (1TB = $23/month)
