Problems solved by technology
When the cluster size is large, especially when the number of volumes is large, this statistical method needs to access the metadata of each volume, so it takes a long time and puts pressure on the underlying query of the cluster, which may affect the normal business IO of the cluster

The invention provides a storage volume performance data management method and system, a terminal and a storage medium. The method comprises the steps of creating and initializing a performance analysis object; writing performance data of the current volume into the performance analysis object; enabling a RBD layer to independently allocate space in the performance analysis object; and receiving IO requests on the RBD layer, and setting a queue to be written into the space according to the IO request times, the request data volume, the request timestamp and other performance records. IO is recorded in the memory only when the service IO is rolled, so that the frequency of interaction with the bottom layer is effectively reduced, and whether the performance recorded in the memory is writteninto the disk to be stored or not is determined according to the situation; A storage system stores historical performance data by itself and breaks away from database cache, the pressure on the cluster caused by regularly querying the performance data is eliminated, and the stability of core services is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of big data service platforms, and in particular relates to a storage volume performance data management method, system, terminal and storage medium. Background technique [0002] In the field of storage systems, customers can format and create arbitrary file systems to use block storage like physical hard disks. Therefore, block storage is suitable for data storage in most general business scenarios, and has become more and more widely used. . In the block storage scenario, the volume is responsible for the main function realization and business output. At present, when querying the change of the business pressure of the cluster or volume within a certain period of time, it is necessary to periodically read the cumulative number of IOs recorded in the metadata of each volume and The total bandwidth is achieved. This process needs to frequently read the metadata of the volume and record it in the database. ...
