promgen - prometheus managemnet tool / simpleclient_java hacks @ Prometheus casual
Promgen is a Prometheus management tool that allows web-based management of server configurations and alerting rules. It addresses the need for an easier way to manage Prometheus server configurations than manually editing YAML files. Promgen stores configuration data in a MySQL database and generates YAML files from the stored configurations. It aims to provide a simple interface for configuring Prometheus exporters, ports, alerts and other settings across multiple servers and projects.
