Query fair usage in Grafana Cloud: What it is and how it affects your logs observability practice

Grafana Cloud's "query fair usage" policy allows users to query up to 100 times their monthly ingested log volume in gigabytes without additional charges, designed to prevent misuse from resource-heavy queries while maintaining cost predictability and infrastructure protection. Users can monitor their query usage through the Grafana dashboard, with options like the Billing/Usage dashboard and a newly redesigned Cost Management experience. Key practices to optimize query usage include configuring alert rules properly, using label selectors and log pipeline filters early, narrowing time ranges, and utilizing aggregation and recording rules for efficiency. Grafana Cloud also offers Loki query limit policies, currently in public preview, to provide control over query result sizes and prevent costly queries, with support and potential changes anticipated before general release. Understanding and managing query usage can prevent unexpected billing surprises, as usage is calculated based on the larger value between ingested and queried gigabytes, impacting the monthly invoice.
