Prometheus Cheat Sheet - How to Join Multiple Metrics (Vector Matching) If the requested label matching doesn't allow to build an unambiguous result, Prometheus just fails the query. PromQL many-to-one and one-to-many vector matching - arithmetic and comparison operations (clickable, 1.2 MB). Many-to-many vector matching (logical/set operations) Prometheus Cheat Sheet - Basics (Metrics, Labels, Time Series, Scraping) Generally, labels are populated by metric producers (servers in the example above). However, in Prometheus, it's possible to enrich a metric with some static labels based on the producer's identity while recording it on the Prometheus node's side. In the wild, it's common for a Prometheus metric to carry multiple labels.

Data model | Prometheus Labels enable Prometheus's dimensional data model: any given combination of labels for the same metric name identifies a particular dimensional instantiation of that metric (for example: all HTTP requests that used the method POST to the /api/tracks handler). The query language allows filtering and aggregation based on these dimensions.
