Why Metric Counts Explode from Thousands to Millions in High‑QPS Systems

A single high‑cardinality label can cause a monitoring system to crash as metric series jump from hundreds of thousands to millions, overwhelming storage, queries, collection, cost, and signal‑to‑noise; the article explains the root cause, impact dimensions, and practical mitigation strategies such as cardinality control, distributed TSDBs, downsampling, pre‑aggregation, and proper division of metrics, traces, and logs.
