![]() Node Exporter should be installed on every client to monitor. No conversion or pre-processing work is required to use Node Exporter and Prometheus together. Node Exporter is closely integrated with Prometheus and shares the same data format. ![]() A full list of the available metrics collected can be found on the Node Exporter GitHub page. Prometheus Node Exporter collects a large number of hardware and kernel metrics, including CPU and memory use. Prometheus retains the metrics it collects, allowing it to build an overview of the long-term performance of the client.Īlthough various statistic collectors can be used on the client nodes, Prometheus recommends its own Node Exporter tool. Prometheus stores the discrete snapshots along with the timestamps indicating when the statistics were retrieved. It maintains a time-series database of the results, polling each client at a predefined interval. The Prometheus server uses the HTTP protocol to poll the client servers for the required data. For security reasons, Prometheus cannot monitor an external node that is not collecting data in this manner. Each client must run a metrics collation tool known as an exporter to collect and expose its internal statistics. Prometheus enables external performance monitoring for all clients, allowing for early detection of possible errors or unexpected behavior. It can monitor its host server as well as external clients. Prometheus is an open-source system monitoring application that collects server metrics at regular intervals. In conjunction with the Grafana visualization solution, Prometheus allows users to visually monitor core server statistics. Prometheus offers a robust node monitoring solution for collecting useful statistics from client nodes. Having visibility of server CPU, memory, and I/O statistics helps them discover and isolate issues before they can cause problems. In the next hands-on lab, we will deep dive into how to write queries in Prometheus and create our own dashboards.Most administrators want to have a comprehensive overview of how their servers are performing. In this hands-on lab, we learned how to install Grafana and add Prometheus as a data source to it. Now you should be able to see an awesome Grafana dashboard displaying the system metrics. Under the "Importing dashboard from " section, Click on the Import button.Ĥ. Add the ID 13978 which will be used to import this dashboard, and then click on Loadģ. Click on add icon in the sidebar and select the import option.Ģ. In this section, we will import a dashboard named Node Exporter Quickstart that includes metrics for CPU, Memory, Disk I/O and Network received and Network Transmitted.ġ. Importing Node Exporter Quickstart Dashboard This means we have successfully added Prometheus as a data source. The message "Data source is working" will appear in the dashboard after testing the connection. Click “Save & Test” to test the connection and to save the new data source. ![]() To know more, check our hands-on lab 'Intro to Prometheus lab'. Note: We have already installed Prometheus in the above steps.
