Mv node_exporter-0.16.0-rc.1.linux-amd64 node_exporter Step 4: Start the node_exporter process. 01:28:08 (173 KB/s) - ‘node_exporter-0.16.0-rc.1.’ saved Step 3: Extract the node_exporter package and rename the directory to ‘node_exporter’ for your convenience.

Create a system user for the installation. Just download the tar, extract and run that’s it! Please do follow the steps below to install node_exporter for collecting system metrics: Connectivity should be enabled from Prometheus server to the end server on port number 9100 to scrape the metrics.You can read this article to get a quick overview on Prometheus and also this will explain the advantages of Prometheus. In this blog post, I will explain how we can install and configure node_exporter on CentOS6 / CentOS7 servers along with the Initd/Systemd script for managing node_exporter process. In the similar way, Prometheus will initiate a connection to this end point and scrape metrics from the server.Īnd now you have data in your Prometheus server, now you can start visualise it from Prometheus or from the Grafana dashboard which has the data source as your Prometheus server. You can initiate a curl call to fetch the metrics and expose it. Once you setup and start the node_exporter on your system, you can start collecting Metrics from your IP:9100/metrics. The default port number of node_exporter is 9100. The node_exporter collects all system level metrics and expose on /metrics endpoint. The default exporter for collecting System level metrics is node_exporter. Once you setup the Prometheus server, you need to configure it to scrape metrics from the remote servers.
