A minimal deployment using kubectl port-forward for local access to your monitoring interfaces, or.In this guide, you will deploy the Prometheus Operator to your Linode Kubernetes Engine (LKE) cluster using Helm, either as: You have successfully install and configure Prometheus and Node_Exporter to monitor matrix of your machine.įollow how-to-integrate-and-visualize-prometheus-metrics-into-grafana-dashboard to setup Grafana and integrate it with Prometheus Data source. You can use the Prometheus expression browser to query for node related metricsĬongrats…. Now, if you check the target in prometheus web UI (, you will be able to see the status as shown below. Step 9- Restart the Prometheus services sudo systemctl status prometheus job_name: 'node_exporter'Īfter adding the node exporter target in YML file it should looks like this Step 8- In the YML file add the node exporter target as shown below. ![]() Login to the Prometheus server(server1) and open the prometheus.yml file. Step 7- Now add Node_Exporter to the target Prometheus server Make sure that port 9100 is open for web interface. Now you will be able to access the Node_Exporter on 9100 port. Step 5- Reload the system daemon and start the node exporter service and enable it on boot system sudo systemctl daemon-reload Step 4- Create a node_exporter service file under systemd sudo vi /etc/systemd/system/node_rviceĪdd the following service file content Sudo mv node_exporter-1.0.0-rc.0.linux-amd64/node_exporter /usr/local/bin/ Step 3- create a user for node exporter and move binary to /usr/local/bin sudo useradd -rs /bin/false nodeusr Step 1- Go to official Prometheus downloads section and download the latest. We will monitor and get the metric of the server2. In this tutorial, we will install the node_exporter on server2. Node_exporter is an exporter of machine metrics that can run on *Nix and Linux system. Make sure that port 9090 is open for web interface. Now you will be able to access the prometheus UI on 9090 port of the prometheus server. Step 12- Reload the systemd service to register the prometheus service and start the prometheus service and check the status sudo systemctl daemon-reload config.file /etc/prometheus/prometheus.yml sudo vi /etc/systemd/system/rviceĬopy the following content to the file. Step 11 – Configure the Prometheus Service File. sudo chown prometheus:prometheus /etc/prometheus/prometheus.yml sudo vi /etc/prometheus/prometheus.ymlĪdd the following configuration to the file. Now we will create the prometheus.yml file. Step 10 – Add and modify Prometheus Configuration file. sudo chown prometheus:prometheus /usr/local/bin/prometheus sudo chown prometheus:prometheus /usr/local/bin/promtool Step 9 – Change the ownership to Prometheus user. Sudo cp prometheuspkg/promtool /usr/local/bin/ Step 8 – Copy prometheus and promtool binary from the prometheuspkg folder to /usr/local/bin sudo cp prometheuspkg/prometheus /usr/local/bin/ Sudo chown -R prometheus:prometheus /etc/prometheus/console_libraries Sudo chown -R prometheus:prometheus /etc/prometheus/consoles Sudo cp -r prometheuspkg/console_libraries /etc/prometheus sudo cp -r prometheuspkg/consoles /etc/prometheus Step 7 – Move the consoles and console_libraries directories from prometheuspkg to /etc/prometheus folder and change the ownership to prometheus user. Step 6 – Rename it as per your preference. Step 5 – Now go to Prometheus downloaded location and extract it. Sudo chown prometheus:prometheus /var/lib/prometheus Sudo chown prometheus:prometheus /etc/prometheus sudo useradd -no-create-home -shell /bin/false prometheus Step 4 – Create a Prometheus user, required directories, and make prometheus user as the owner of those directories. Paste the copied URL after wget in the below command: wget Run the following command to download package. Go to official Prometheus downloads page, and copy the URL of Linux “tar” file. Step 2 – Disable SELinux sudo vim /etc/sysconfig/selinuxĬhange “SELINUX=enforcing” to “SELINUX=disabled”.Ĭhange, save the file and then Reboot the System sudo Reboot Step 1 – Update System sudo yum update -y Login to Server1 Terminal as a Sudo/Non-Sudo user. One is Server1 and 2nd Server2 is for Node Exporter Configure Prometheus on Centos Prerequisites: The Prometheus monitoring system includes a rich, multidimensional data model, a concise and powerful query language called PromQL, an efficient embedded timeseries database, and over 150 integrations with third-party systems. In 2016, Prometheus was the second project accepted into the Cloud Native Computing Foundation after Kubernetes, and also to the second to graduate in 2018. Prometheus® is an open source monitoring system developed by engineers at SoundCloud in 2012.
