Prometheus combines multiple key features to allow you to monitor your systems in an effective way:

• A dimensional (label-based) data model that allows you to slice tracked metrics by key features,
• A powerful query language (PromQL) optimized for working with time series,
• Integration of time series processing and alerting,
• Integration with service discovery mechanisms to deal with dynamic environments,
• Operational simplicity,
• An efficient implementation in Go.

We will discuss each of these points in more detail in the following sections.
