 A simple HTTP API with a database, for keeping track of testing lab resource utilization across test atuomation sessions.
 The utility, `shovel` script is designed to extract the resource information by scraping TSDB (prometheus) metrics and pushing the processed data to `rekuper` database by calling its API endpoints. It can be regularly called by `cron` or spawned as a OSP `cron job` pod.
