Kubernetes Event Monitoring

# Watch GPU pod events
kubectl get events --watch --field-selector=reason=Scheduled,reason=Pulled,reason=Failed

# Monitor GPU utilization via exec
kubectl exec -it deployment/inference -- nvidia-smi --query-gpu=utilization.gpu,memory.used --format=csv -l 5

Prometheus GPU Metrics

# DCGM exporter for GPU metrics (pre-installed on CKS)
# Key metrics:
# DCGM_FI_DEV_GPU_UTIL - GPU utilization %
# DCGM_FI_DEV_FB_USED - GPU memory used
# DCGM_FI_DEV_POWER_USAGE - Power draw

Slack Alert Integration

import subprocess, json, requests

def check_inference_health(deployment: str, slack_url: str):
    result = subprocess.run(
        ["kubectl", "get", "deployment", deployment, "-o", "json"],
        capture_output=True, text=True,
    )
    deploy = json.loads(result.stdout)
    ready = deploy["status"].get("readyReplicas", 0)
    desired = deploy["spec"]["replicas"]

    if ready < desired:
        requests.post(slack_url, json={
            "text": f"CoreWeave: {deployment} has {ready}/{desired} replicas ready"
        })
