Prometheus is a very independent framework that does not impact your existing cloud or in-premise infrastructure.Using Prometheus in the landscape of DevOps and SREs. Now I have talked about how to install and use Prometheus along with Grafana, let's see what are the advantages of You should be able to see the memory dashboard Click load and then select the data source as Prometheus.Click on the result and then copy the board ID.Goto Grafana Dashboard and search for Linux Memory.Now after settings the data source we can import pre-existing opensource dashboard from Grafana Labs using the Prometheus datasource 4.2 Import Grafana Dashboard from Grafana Labs Enter the hostname or IP address of the prometheus server.Select the Prometheus as preferred data source.Goto your Grafana Dashboard and click on Gear(Settings Icon)->Data Sources.4.1 Let's create a Prometheus Datasource inside Grafana Dashboard It relies on Datasource connection towards the Prometheus server because Prometheus server is responsible for Installed the Prometheus Server, Node Exporter as well as Grafana Server but there is a connection betweenĪs I mentioned earlier Grafana is an analytics and visualization dashboard, Grafana does not store data, but instead The next step after installing the Grafana Server would be to set up the Grafana Dashboard. The default login Username: Password for accessing the Grafana dashboard is admin: adminĬhange the default admin password after the login Access the Grafana Dashboard using Grafana Dashboard login on.(Note- Replace x.xx.x with the downloaded version of node exporter)ġ 2 sudo systemctl enable rvice (In my case I am using Ubuntu linuxĮxtract the download node exporter binary file. Here are the download and installation steps -ĭownload the binary of Node exporter based on the operating system. Is used for collecting various hardware and kernel-level metrics of your machine. There are many third-party Node exporters which can be used by SREs as well as DevOps based on their application needs.īut primarily we look for the following metrics -Īfter installing the Prometheus in the previous step the next package we are going to install is ** Node Exporter Which Prometheus can understand and with the help of the prometheus server those statistics can be exposed on port Node exporter is responsible for fetching the statistics from various hardware and virtual resources in the format ![]() You can access the Prometheus metrics UI by visint Run prometheus serverĢ. You can access the Prometheus graph UI by visint Run prometheus server The Prometheus server should start on port 9090 Start the prometheus server with the command. Go into the extracted directory cd prometheus-x.xx.x. (Note- Replace x.xx.x with the downloaded version of Prometheus)ġ 2 tar xvfz prometheus-x.xx.x. (Note- Here x.xx.x is version number) Download prometheus binaryĮxtract the download binary file. Goto Download Page of Prometheus and select the prometheus-x.xx.x. file for download. But to keep the installation simple we are going to use the pre-compiled binaries for installing Prometheus onto my Ubuntu Linux machine. Prometheus has a various ways of installation for example - pre-compiled binaries, from source, Docker. Is Grafana Labs where you can go and download the dashboard prepared by other developers so that you do not ![]() Also, Grafana is usedįor sending notifications and mail alerts based on various thresholds. Grafana does not store anyĭata, but instead, it relies on Prometheus to send the data so that dashboard can be prepared. Grafana is an open-source analytics and visualization tool. What is Grafana? - In Lehman's term Grafana is a User interface for viewing the metrics scraped by Prometheusįrom various resources. Prometheus architecture is really scalable and 3rd party libraries and makes Prometheus has superb support API which makes Prometheus integration withĪny resource present in the Datacenter. ![]() Prometheus scraps the data with the timestamp which can be stored onĪ server and accessed using the PromQL. (CPU, VM, Cloud Virtual Machine, Router, etc.). ![]() What is Prometheus? - It is an open-source tool for scrapping the performance metrics of any given hardware resource
