Operation and maintenance data analysis method and device, equipment and medium

The invention provides an operation and maintenance data analysis method and device, equipment and a medium, and can be applied to the technical field of computers and the technical field of data processing. The method comprises the following steps: distributing multi-dimensional operation and maintenance data samples related to a database operation state to a plurality of first data spaces according to a first preset rule; for each first data space in the plurality of first data spaces, clustering the multi-dimensional operation and maintenance data in the first data space to obtain a first local feature; clustering the first local features respectively corresponding to the plurality of first data spaces to obtain a plurality of first feature spaces; clustering the plurality of first feature spaces to obtain a first global feature; and determining an operation state global feature of the database according to the first global feature and the plurality of first local features, and determining an operation sta
