Prometheus node exporter memory usage12/15/2023 ![]() ![]() Install and Configure Prometheus on Debian 9 Install and Configure Prometheus on Fedora 29/Fedora 28 You can check our other articles by following the links below In our next guide, we will learn how to integrate the Prometheus with Grafana for better visualization. You have successfully set up Prometheus node exporter to monitor remote Linux host. To see the Graphical view, click on the Graph tab. Ensure that the times in both Prometheus server and target are synchronized. For example, to check the target’s available memory, you would just type, node_memory_MemAvailable_bytes and click execute. To view the metrics from Prometheus Web interface, and enter any expression for a specific metric you want to see. # TYPE node_filesystem_device_error gauge # HELP node_filesystem_device_error Whether an error occurred while getting statistics for the given device. For example curl | grep node_ | grep filesystem To verify that your Prometheus server can receive metrics from your node, run the command below curl To check for the system metrics, you can grep for the metrics prefixed with node_. If all is well, your target should be up as shown above. Login to Prometheus web interface and check the status of your Target. Restart Prometheus service systemctl restart prometheus # The job name is added as a label `job=` to any timeseries scraped from this config. Next, login to Prometheus server and add your Node Exporter target. LISTEN 0 128 *:9100 *:* users:(("node_exporter",pid=4162,fd=3)) Add Node Exporter Target to Prometheus Default Prometheus port allocations description are here. Loaded: loaded (/etc/systemd/system/node_rvice disabled vendor preset: enabled)Īctive: active (running) since Thu 10:24:51 EAT 7s agoĬGroup: /system.slice/node_rvice To check status systemctl status node_rvice Start and enable Node Exporter to run on system boot. For example, to collect CPU, Disk usage and memory statistics, you would set the ExecStart line as ExecStart=/usr/local/bin/node_exporter -collector.cpu minfo -collector.loadavg -collector.filesystemĪfter that, reload the systemd manager configuration. vim /etc/systemd/system/node_rvice Īs stated in the Collectors section, you can configure Node Exporter to expose specific system metrics. To run the Node Exporter as a service, you need to create a Systemd service file for it. chown node_exporter:node_exporter /usr/local/bin/node_exporter Running Node Exporter Set the user and group ownership of the node_exporter binary to node_exporter user created above. cp node_exporter-0.18.0.linux-amd64/node_exporter /usr/local/bin/ tar xzf node_exporter-0.18.0.Ĭopy the Node Exporter binary from the archive folder to /usr/local/bin. Once the download is done, run the command below to extract it. Next, navigate to Prometheus downloads page and grab the Node Exporter tarball. Uid=998(node_exporter) gid=997(node_exporter) groups=997(node_exporter) Download and Install Node Exporter This will create a node_exporter user with the same group as the username. useradd -M -r -s /bin/false node_exporter Hence, run the commands below to create a non-login node_exporter user. To run the Node Exporter safely, you need to create a user for it. ![]() Installing Prometheus Node Exporter on Ubuntu 18.04 Create Node Exporter System User This guide uses Ubuntu 18.04 as a system to collect system metrics from using the Node Exporter. Install Prometheus on Ubuntu 18.04 Monitor Linux System Metrics with Prometheus Node Exporter ![]() Learn how to install Prometheus server on Ubuntu 18.04 by visiting the link below Node Exporter is a Prometheus exporter for hardware and OS metrics exposed by *NIX kernels such as CPU, disk, memory usage etc with pluggable metrics collectors. In this tutoria, we are going to learn how to monitor Linux system metrics with Prometheus Node Exporter. ![]()
