How do I know if node exporter is running?
Step 5: check the node exporter status to make sure it is running in the active state. Step 6: Enable the node exporter service to the system startup. Now, node exporter would be exporting metrics on port 9100. You can see all the server metrics by visiting your server URL on /metrics as shown below.
What is a node exporter?
Node Exporter is an ‘official’ exporter that collects technical information from Linux nodes, such as CPU, Disk, Memory statistics. It is a base brick on most of prometheus-based monitoring setup.
What port does node exporter run on?
Now, after starting the service, node exporter is ready to export metrics on port 9100. To view all the server metrics, you can curl your server URL on /metrics, as shown below.
What is node exporter in Kubernetes?
Deploy node exporter on all the Kubernetes nodes as a daemonset. Daemonset makes sure one instance of node-exporter is running in all the nodes. It exposes all the node metrics on port 9100 on the /metrics endpoint. Create a service that listens on port 9100 and points to all the daemonset node exporter pods.
How do I know if Prometheus is running?
To verify that node_exporter is running, open your browser and navigate to http://<IP of Node exporter host>:9100/metrics. All the metrics collected will be displayed; these are the same metrics Prometheus will scrape.
How do I run node exporter as a service?
- Create a node_exporter user to run the node exporter service. sudo useradd -rs /bin/false node_exporter.
- Create a node_exporter service file under systemd.
- Reload the system daemon and start the node exporter service.
How do I run node exporter in the background?
Running Node exporter in CentOS 7 is very straightforward. Download node exporter package and untar the package. It is always better to rename the folder for better management. Node exporter has to be run always in the background to collect the metrics and expose the metrics as http to be scraped by Prometheus.
What is cAdvisor?
cAdvisor ( Container Advisor ) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects aggregates processes and exports information about running containers. This data is exported by container and machine-wide.

What is Prometheus Alertmanager?
Alertmanager is a Prometheus component that enables you to configure and manage alerts sent by the Prometheus server and to route them to notification, paging, and automation systems. Learn more about Prometheus and monitoring best practices in our article about DevOps monitoring.
What is blackbox exporter?
The Blackbox exporter is a tool that allows engineers to monitor HTTP, DNS, TCP and ICMP endpoints. Results can be visualized in modern dashboard tools such as Grafana.
What port does Grafana run on?
Note: The default Grafana port is 3000.
What is Thanos Prometheus?
Thanos, simply put, is a “highly available Prometheus setup with long-term storage capabilities”. Thanos allows you to aggregate data from multiple Prometheus instances and query them, all from a single endpoint. Thanos also automatically deals with duplicate metrics that may arise from multiple Prometheus instances.
What node exporter will do?
A Node Exporter run as a systemd service that will periodically (every 1 second) gather all the metrics of your system. A dashboard solution, in this case Grafana, displaying metrics gathered from Prometheus. We are not going to build every single panel by ourselves.
What is KUBE Prometheus?
kube-prometheus. This repository collects Kubernetes manifests, Grafana dashboards, and Prometheus rules combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with Prometheus using the Prometheus Operator. The content of this project is written in jsonnet.
