Prometheus collects data in the form of time series. The time series are built through a pull model: the Prometheus server queries a list of data sources (sometimes called exporters) at a specific polling frequency. Each of the data sources serves the current values of the metrics for that data source at the endpoint queried by Prometheus.
Grafana was first released in 2014 by Torkel Ödegaard as an offshoot of a project at Orbitz. It targeted time series databases such as InfluxDB, OpenTSDB, and Prometheus, but evolved to support relational databases such as MySQL/MariaDB, PostgreSQL and Microsoft SQL Server. [13] In 2019, Grafana Labs secured $24 million in Series A funding. [14]

In software engineering and development, a software metric is a standard of measure of a degree to which a software system or process possesses some property. [1] [2] Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonyms.
Halstead's goal was to identify measurable properties of software, and the relations between them. This is similar to the identification of measurable properties of matter (like the volume, mass, and pressure of a gas) and the relationships between them (analogous to the gas equation). Thus his metrics are actually not just complexity metrics.
