The invention relates to a hot object monitoring method and device. The method comprises the steps of monitoring access heats of a plurality of objects comprising documents or directories; determining one or more hot objects from the a plurality of objects which are objects whose access heat is over preset heat threshold; determining whether the directory is a hot directory based on the number of the hot objects, total number of the a plurality of objects and preset ratio threshold; determining the directory where the a plurality of objects are; setting zone bit of the directory; and monitoring the access heat of the directory based on hot zone bit of the directory. The hot object monitoring method and device can monitor whether document or directory in current depth and depth one level below the current depth in the tree structure is hot, automatically adjust monitoring depth from a plurality of objects to directory of the monitoring objects, and identify hot distribution of objects in each depth in the whole document system by loops.
Description
technical field [0001] The invention relates to the field of storage technologies, in particular to a method and device for monitoring hotspots. Background technique [0002] Most of the file system files or directories in the storage space allocation in the memory now use the method of index node + data block, the metadata of the file or directory and the data block number of the file are stored in the index node, in the corresponding The specific content of the file or directory is stored in the data block of the file or directory. Each file or directory has an index node, and the number of data blocks required is determined according to the file size. [0003] Due to the influence of file or directory distribution, there will be certain hotspot associations between different regions. When identifying hotspot data in the file system, the popularity of each data block is usually counted at the granularity of the data block, and it is impossible to judge whether the file is...
