Dashboard Span Query Cost Runaway
infoDynatrace AI Observability dashboards use span queries that consume DPS trace capacity even when no data is shown. Without sampling controls, exploratory dashboards can inflate query costs unexpectedly.
Monitor DPS trace query consumption via Dynatrace billing/usage metrics. Alert if query costs spike without corresponding increases in actual trace ingestion (langchain_chain_run counts stable). Check if new or cloned dashboards are querying large time ranges without sampling.
Use sampling variables on Dynatrace AI Observability dashboards to reduce queried span volume. Prefer metrics-based tiles over raw span queries where possible. Restrict dashboard access to relevant users and delete unused exploratory dashboards. Set up cost budgets and alerts in Dynatrace.
