Prometheus is widely used to collect metrics including node CPU usage.Step 2: Alerting mechanism
Alertmanager works with Prometheus to send alerts based on defined thresholds.Step 3: Why other options fail
Manual checks are not scalable; ignoring node metrics misses cluster-wide issues; Kubernetes events don't provide detailed CPU metrics.Final Answer:
Use Prometheus to scrape node metrics and configure Alertmanager with CPU usage thresholds -> Option CQuick Check:
Prometheus + Alertmanager is best practice for CPU alerts [OK]
Quick Trick: Combine Prometheus metrics with Alertmanager alerts [OK]
