Overview

CoreWeave runs GPU-intensive workloads on Kubernetes where hardware failures, memory exhaustion, and underutilization directly impact cost and reliability. Observability must cover DCGM GPU metrics, Kubernetes pod health, inference latency, and job completion rates. Proactive monitoring prevents wasted spend on idle GPUs and catches OOM conditions before they cascade.

Key Metrics

Instrumentation

async function trackInference(model: string, fn: () => Promise<any>) {
  const start = Date.now();
  try {
    const result = await fn();
    metrics.record('coreweave.inference.latency', Date.now() - start, { model, status: 'ok' });
    metrics.increment('coreweave.inference.completed', { model });
    return result;
  } catch (err) {
    metrics.increment('coreweave.inference.errors', { model, error: err.code });
    throw err;
  }
}

Health Check Dashboard

async function coreweaveHealth(): Promise<Record<string, string>> {
  const gpu = await queryPrometheus('avg(DCGM_FI_DEV_GPU_UTIL)');
  const mem = await queryPrometheus('avg(DCGM_FI_DEV_FB_USED/(DCGM_FI_DEV_FB_USED+DCGM_FI_DEV_FB_FREE))');
  const pods = await queryPrometheus('kube_deployment_status_replicas_available{namespace="inference"}');
  return {
    gpu_utilization: gpu > 20 ? 'healthy' : 'underutilized',
    gpu_memory: mem < 0.9 ? 'healthy' : 'critical',
    inference_pods: pods > 0 ? 'healthy' : 'down',
  };
}

Alerting Rules

const alerts = [
  { metric: 'DCGM_FI_DEV_GPU_UTIL', condition: 'avg < 20', window: '30m', severity: 'warning' },
  { metric: 'gpu_memory_pct', condition: '> 0.95', window: '5m', severity: 'critical' },
  { metric: 'inference_latency_p99', condition: '> 500ms', window: '10m', severity: 'warning' },
  { metric: 'pod_restart_count', condition: '> 3', window: '15m', severity: 'critical' },
];

Structured Logging

function logGpuEvent(event: string, node: string, data: Record<string, any>) {
  console.log(JSON.stringify({
    service: 'coreweave', event, node,
    gpu_model: data.gpu_model, utilization: data.util,
    memory_pct: data.memPct, temperature: data.temp,
    timestamp: new Date().toISOString(),
  }));
}
