Resource usage amount query method and device, equipment and storage medium

The invention provides a resource usage amount query method and device, equipment and a storage medium. The method comprises the following steps: receiving a resource usage amount query request sent by user query equipment; the query request comprises a total query time period, a query period and a query dimension; calculating each query sub-time period according to the query total time period and the query period; when each query sub-time period arrives, obtaining resource usage amount time sequence data of the corresponding dimension from the target relational database according to the query dimension; the resource usage amount time sequence data comprises a timestamp when the resource usage amount time sequence data is generated and a corresponding resource usage amount; querying the resource usage amount corresponding to each query sub-time period in each resource usage amount time sequence data; generating a resource usage amount curve graph in the total query time period according to the resource usage
