Query and analyze a Dynatrace tenant's ACTUAL billing and usage data with DQL against dt.system.events — DPS consumption breakdown, cost-normalized spend ranking, included volume deduction, chargeback/showback, cost drivers, spending trends, cost investigation, metrics ingest optimization, query cost attribution, workflow total cost, entity-level cost drill-down (RUM, hosts, synthetic, K8s), and AI/LLM cost (AI Units, AI Function Standard Calls, AI-generated query consumption). Directs licensing/entitlement questions to documentation (not via DQL). USE ONLY to query/analyze 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 documentation. Do NOT use for making DQL queries faster or cheaper to run (query optimization, reducing scanned data/consumption per run, filter-early best practices) — that belongs to dt-dql-essentials. This skill MEASURES consumption; it does not tune queries.
