Query and analyze a Dynatrace tenant's ACTUAL billing and usage data with DQL on dt.system.events — DPS consumption breakdown, cost-normalized spend ranking, included volume deduction, chargeback/showback, cost drivers, spending trends, cost investigation, log import cost, metrics ingest optimization, drop/remove a metric or dimension from ingestion, reduce metric cardinality, metric usage, query cost attribution, workflow total cost, entity cost drill-down (RUM, hosts, synthetic, K8s), AI/LLM cost (AI Units, AI Function Standard Calls). Directs licensing/entitlement questions (am I entitled to use X?) to docs (not via DQL). USE ONLY for the tenant's actual consumption. Do NOT use for conceptual 'explain' questions about how DPS billing/pricing works or what units/weights/the rate card mean — see Dynatrace docs. Do NOT use for tuning DQL queries to be faster or cheaper to run (query optimization, reducing scanned data/consumption per run, filter-early best practices) — that belongs to dt-dql-essentials.
