Also we have verified by checking the data of the target Linux hosts from the Prometheus web interface. Select "Prometheus" as the type. Grafana . Prometheus Data Source for Grafana. 2. The Grafana installation was already covered extensively in our of our previous articles, so make sure to read it to setup your Grafana server. Cortex. Prometheus installation. What is Grafana? In my previous blogs , I have explained in detail on How to.From the above articles , We did a setup of Node exporter on the target Linux hosts and Prometheus scraps the metrics from the Node exporters.Also we have verified by checking the data of the target Linux hosts from the Prometheus web interface.In this guide ,We will see how to setup Grafana and intergrate prometheus as a datasource and setup a monitoring.Grafana is an open source monitoring tool with Dashboards and Visualizations.It can integrated with several other services such as Prometheus , Elasticsearch , Cloudwatch , Loki , InfluxDB , Graphite etc.Grafana also helps us to alert to several channels such as Email , Slack , Opsgenie , Webhook , Telegram etc.Make sure you have the root access to perform the below actions.Adding the stable version of grafana to the repository.Now we have to update the repository and install grafana packages.Once the grafana packages are installed.But default the systemd service will be created for the same.Lets start the grafana service using the below command.Enable the grafana service to start on the system boot.Grafana listens on the port 3000 by default , We can verify the same using below command.We have installed the grafana service , Now its time to access the Grafana web interface.To open the dashboard , The url as follows.Note : If you’re hosting grafana in EC2 instance , Make sure port 3000 is whitelisted in the Security group.The default username and the password to login to Grafana web interface is.Then it will ask us to set the new password for the admin user.We have successfully implemented the Grafana Monitoring tool , The dashboard is as shown below.To check the node exporters metrics which is alread stored in the prometheus server , We need to integrate prometheus with grafana.Under Configuration , You can add the datasources here.Grafana can query data from these datasource to plot the graphs.For this tutorial , We are going to use Prometheus as the datasource.Here we will asked to provide few information such as Prometheus URL.Provide a name for the datasource , and then provide the ip address and the port in which Prometheus is Running.Grafana should be able to access port 9090 and it should be whitelisted in the Firewall.We have now integrated both the services.For the Grafana to alert to a specific channel or medium, We need to add / configure the same.Provide a name for the Notification Channel and then choose Type.Now We have datasource and the alerting mechanism.Lets go ahead and setup dashboard and configure the alerting for the same.We can setup dashboard by ourselves from the scratch or we can import the existing dashboard from Grafana.To setup a dashboard for the Node Exporter metrics.It will ask us the id of the dashboard. IV – Installing Grafana. 5. 4. The id to import the Node exporter graph is,Give a name for the dashboard and then choose the data source as.It will collect all the metrics from the Prometheus data source and plot the graph as per the metrics such as CPU usage , Disk usage , Memory usage etc.Make sure the dashboard id’s are chose as per the version of the Node exporter installed , Else It won’t show up any data in the graphs.Using the dashboard we have created , We can check the resources used by the servers.We can setup a dashboard where we can check the metrics of the servers and at the same time we can check the alert status.Once the dashboard is imported , You can see Disk usage , Memory and CPU usages.To setup alerting for this, Lets say If the CPU usage is above 80% (for example) alert it to the Notification channel we have configured.From the drop down of the CPU usage graph , Choose,From the left navigation pane , Choose the.Provide a name for the alert , and configure how often the data should be evaluated & based on that If the usage if above the threshold we set , It will alert us.And provide a message for the alert ,For better Understanding.Repeat the same procedures for the other metrics / graphs.We can also configure multiple conditions while configuring alerting by various levels such as Warning , High and Critical.We have successfully implemented a complete Monitoring and Alerting setup for the Linux servers using Node exporter , Prometheus and Grafana.I hope you really find it helpful.Please do check out my other blogs.Monitoring Linux nodes using Node Exporter. To create a Prometheus data source in Grafana: 1. Click on the "cogwheel" in the sidebar to open the Configuration menu. Graphite. Grafana Enterprise. Set the appropriate Prometheus server URL (for example, http://localhost:9090/) 6. 7. We are now ready to install Grafana to visualize Prometheus metrics.
