The Prometheus monitoring system and time series database.
As Prometheus is a monitoring software that saves data in a timeseries database, it can take up massive amounts of disk space. Due to Prometheus design, a huge memory consumption is also possible. To get started, a minimum of 3GB RAM and >=2.5GB disk space is recommended. Keep in mind that those numbers can grow pretty quick for large monitored environments!
