I have Prometheus setup to scrape node_exporter from many Linux VMs. Hot Network Questions Convincing the contrapositive is equivalent Kubernetes-pods will request metrics from each pod in the cluster, including Node Exporter and Prometheus, while kubernetes-nodes will use service discovery to get names for all the nodes, and Complete code: here Above is a snippet of how metrics are added to Kafka Brokers and Zookeeper. So that's exact situation where counter metric (such as node_netstat_Tcp_ActiveOpens) comes handy. The windows_exporter will expose all metrics from enabled collectors by default. Should I: A: Set up a new deployment with a single container running the nginx exporter, then provide ingress with a service. This chart bootstraps a prometheus Node Exporter deployment on a Kubernetes cluster using the Helm package manager. This is installed in a Docker Desktop The reason that node-exporter metrics in prometheus lack node information but have pod information is because prometheus-operator provides a ServiceMonitor for node-exporter, which sets up a scrape configuration with a kubernetes_sd_config. node_exporter. Node-Exporter – Prometheus works by scraping data from a variety of configurable sources called exporters. node-exporter, a Prometheus exporter that runs on cluster nodes and provides OS and hardware metrics like CPU and memory usage to Prometheus.
