I have already done it.It’s an open-source Prometheus exporter which collects and exposes hardware and OS metrics like CPU, System Load, RAM, Network Traffic, Disk, etc. In the next step, you can install Alertmanager, configure Prometheus to use it, create alerts and send them to Alertmanager. Select Prometehus as datasource and click Import button.ĩ. Then import Node Exporter Full Dashboard by id which is 1860. Click the plus icon and select Import dashboard.ħ. It can be either local prometehus or one that works on google cloud.Ħ. Add Prometheus URL that we configured before. Once you access the Grafana, you will need to login. You will just need to change name to grafana-port and TCP port to 3000. If you use google cloud, follow steps as we did when configuring promethus and node exporter. Create node_exporter user, required directory and make node-exporter user as owner of the directory.įirewall-cmd -permanent -add-port 3000/tcp Therefore, to remove this issue, it is better to setup Node-exporter as Systemd service.Ģ. If you want to run other commands you will need to stop it by Ctrl + C. The problem with this method is that it will keep your terminal running and you will not be able to run other commands in the current terminal session. node_exporter from the extracted directory. In step 3, we said that in order to start node-exporter we need to use command. Setup Node-exporter as Systemd Service ġ. You can also access Node Exporter by visiting for local machine or for google cloud instance.Ģ.Go to external IP of the instance using port 9100.Then you can delete zip file.įirewall-cmd -permanent -add-port 9100/tcp Create directory called node-exporter and extract the downloaded file to that directory. At the time of writing this tutorial, latest stable version is 1.4.0.Ģ. From Prometheus Download page, download latest stable version of node exporter. You can also write your own exporter to expose your application’s metrics but it is out of scope of this tutorial.ġ. Node Exporter is one of the simple exporters out there and it is used to collect basic system metrics from the Linux machine. Exporters are used to expose metrics so that Prometheus can collect. There are a lot of exporters which are provided by Prometheus itself.Go to Prometheus Web UI address - for local machine or for google cloud instance. Create prometheus user, required directories and make prometheus user as owner of the directories.Ĩ. Therefore, to remove this issue, it is better to setup Prometheus as Systemd service.Ģ. prometheus from the extracted directory. In step 3, we said that in order to start prometheus server we need to use command. You can also access Prometheus metrics by visiting for local machine or for google cloud instance.Ģ.We will add another instance when we install node exporter in part 2. If we add IP adresses of other instances to configuration file of prometheus, it will display those instances,as well. Right now, we only have one instance and since the prometheus runs on this instance, it will display this nessage up. If you execute up command, it will show you instances which are in UP state.Go to external IP of the instance using port 9090.Use below configuration and press create button. If you use google cloud, follow these steps: Then you can delete zip file.įirewall-cmd -permanent -add-port 9090/tcp Create directory called prometheus and extract the downloaded file to that directory. Copy the link address of the file that you want to download and then run the command in your terminal.Ģ. You can use wget command to download the compressed file. At the time of writing this tutorial, latest stable version is 2.37.2. From Prometheus Download page, download latest stable version. Promtheus has different ways for installation but for a sake of simplicity, I will use pre-compiled binary files. I will install prometheus in my Linux Machine - CentOS which runs in Google Cloud but you can use any Linux distribution that is on the cloud or in your local envrionment. It stores a variety of events such as memory consumption, CPU and network uitilization, indiviudal incoming/outgoing requets and etc. It is an open-source systems monitoring and alerting toolkit which collects and aggregates metrics as time series data.Setting Up Prometheus What is Prometheus? We will use Node Exporter to expose basic metrics and then create Grafana dashboard to monitor our servers. Prometheus is an open-source systems monitoring and alerting toolkit which collects and aggregates metrics as time series data.
