Prometheus Monitoring Server

Prometheus is an open source monitoring, querying and alerting tool. Originally built by Soundcloud in 2012, the feature-rich tool has been adopted by several companies to monitor their IT infrastructure and ensure all systems are running smoothly. Prometheus allows you to query and pull time-series metrics such as CPU & memory utilization over HTTP protocol and visualize them on real-time graphs. You can also configure Prometheus to push alerts in the event of a node or service downtime and integrate it with other third-party monitoring tools such as Grafana for enhanced data visualization.<ref>How to Install Prometheus on CentOS 8 / RHEL 8</ref>

The above referenced article, How to Install Prometheus on CentOS 8 / RHEL 8 provides instructions for a basic prometheus server and system monitoring (node_exporter) capability. These instructions were followed to get the server functional on Lamppost, and the node_exporter tool installed on the development kubernetes cluster.
