Data processing method and device

The embodiment of the invention discloses a data processing method and device. The data processing method comprises the steps that accessed monitoring data of service nodes is acquired and represents accessed feature information of the service nodes and the services of the service nodes based on at least one dimension; fragmentation processing is conducted on the monitoring data based on the reporting time of the monitoring data to obtain fragmented monitoring data, wherein the time slices used during the fragmentation processing are determined based on the real-timeliness requirement of monitoring; target dimensions are determined and include at least one dimension; merging processing is conducted on the fragmented monitoring data based on the target dimensions to obtain a merging processing result of the fragmented monitoring data of the target dimensions. By the adoption of the data processing method, efficient merging processing can be conducted on massive monitoring data so as to warming analysis or netw
