A Vector metric event represents a numerical operation performed on a time series. Unlike other tools, metrics in Vector are first class citizens, they are not represented as structured logs. This makes them interoperable with various metrics services without the need for any transformation.
Vector’s metric data model favors accuracy and correctness over ideological purity. Therefore, Vector’s metric types are a conglomeration of various metric types found in the wild, such as Prometheus and StatsD. This ensures metric data is correctly interoperable between systems.
