Alert if there are no logs from a node
You need to monitor node resource consumption to ensure all nodes in your cluster are healthy. Use following data: enough nodes in your cluster, resource allocation is sufficient for deployed applications, etcd is healthy, you're not hitting any resources.
NewRelic solution can helps you with that, it tracks resource consumption (used cores and memory) for each Kubernetes node. That lets you track the number of network requests sent across containers on different nodes within a distributed service.
If you set alerts, you’ll be notified if node stop reporting (has no logs) or if a node’s CPU or memory usage drops below a desired threshold.
