![]() ![]() I also did: kubectl port-forward prometheus-deployment-5d79b5f65b-tkpd2 8080:9090 -n monitoring and when I access the prometheus web UI > Status > Targets, I don't find node-exporters there. I can see the endpoints, as well: kubectl get endpoints -n monitoring NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES The pods seem to be running properly: kubectl get pods -namespace=monitoring -o wide I installed prometheus and node-exporter on top of it based on: Rate(node_network_receive_bytes_total)įollow “ Integrate And Visualize Prometheus Metrics In Grafana” blog to visualize the node exporter metrics in Grafana.I have a Kubernetes cluster set up using kubeadm. Following are the few key node metrics you can use to find its statistics. Now, if you check the target in prometheus web UI (, you will be able to see the status as shown below.Īlso, you can use the Prometheus expression browser to query for node related metrics. Step 3: Restart the prometheus service for the configuration changes to take place. Job name can be your server hostname or IP for identification purposes. Change 10.142.0.3 with your server IP where you have setup node exporter. Step 2: Under the scrape config section add the node exporter target as shown below. ![]() Step 1: Login to the Prometheus server and open the prometheus.yml file. Note: This configuration should be done on the Prometheus server. Now that we have the node exporter up and running on the server, we have to add this server a target on the Prometheus server configuration. Configure the Server as Target on Prometheus Server ![]() You can see all the server metrics by visiting your server URL on /metrics as shown below. Now, node exporter would be exporting metrics on port 9100. Step 6: Enable the node exporter service to the system startup. Step 5: check the node exporter status to make sure it is running in the active state. Step 4: Reload the system daemon and star the node exporter service. Step 3: Add the following service file content to the service file and save it. Step 2: Create a node_exporter service file under systemd. sudo useradd -rs /bin/false node_exporter Step 1: Create a node_exporter user to run the node exporter service. Step 3: Move the node export binary to /usr/local/bin sudo mv node_exporter-0.18.1.linux-amd64/node_exporter /usr/local/bin/ Create a Custom Node Exporter Service Step 2: Unpack the tarball tar -xvf node_exporter-0.18.1. You should check the Prometheus downloads section for the latest version and update this command to get that package. Step 1: Download the latest node exporter package. Port 9100 opened in server firewall as Prometheus reads metrics on this port.If you would like to setup Prometheus, please see the Prometheus setup guide for Linux. Prometheus Node Exporter needs Prometheus server to be up and running.In this guide, you will learn how to setup Prometheus node exporter on a Linux server to export all node level metrics to the Prometheus server. ![]() Node exporter is the best way to collect all the Linux server related metrics and statistics for monitoring. ![]()
