Lightning Talk: Metrics Make Meaning: Why the UpDownCounter?

summary
OpenTelemetry adds a third numeric instrument, UpDownCounter, to preserve semantics when erasing attributes so collectors can remove attributes without changing meaning. Counters (no meaningful resets) suit rates, gauges suit measurements (mean aggregation), UpDownCounters report totals that go up and down, aggregate by sum, and represent current value without resets. Examples include parking‑lot in/out sensors and home solar grid meters. Claim: semantic instruments let pipelines auto‑transform metrics to reduce cardinality, control cost, and build meaningful dashboards.
