IFO4
Loading...Numeric measurements aggregated over time, indexed by a small set of high-cardinality-bounded dimensions, used to characterise the rate, throughput, latency, and saturation of a system. Metrics are cheap to query and cheap to retain at long horizons but lose individual-event detail; they complement rather than substitute for logs and traces. The federation expects that metric naming, units, and dimensions follow a documented convention and that high-cardinality dimensions be controlled to prevent storage explosion under UFMS-001:2.4.
The word metric in measurement contexts dates to the eighteenth century; the modern observability usage emerged in the carrier-grade monitoring tradition of the late twentieth century and was popularised in cloud through Prometheus from 2012.
Federation members must publish a metric naming convention and a cardinality budget per service. Cardinality breach without remediation within thirty days is reported under MEV-Annex:3.2.
