Adaptive Metrics is a newly introduced feature in Grafana Cloud aimed at optimizing metrics management by reducing time series cardinality, thereby lowering associated costs. This tool aggregates unused and partially used metrics into lower cardinality versions, helping users manage exorbitant data storage and retrieval expenses in cloud-native environments. By analyzing usage patterns, Adaptive Metrics provides recommendations for aggregating metrics without compromising the functionality of existing dashboards and alerts. The feature is available to all Grafana Cloud users, including those on the free tier, and offers a flexible approach allowing users to tailor aggregation rules based on their unique observability needs. Initial implementations have shown significant reductions in time series volume, with potential savings between 20% and 50% across various user environments.
