Big data task exception detection method and device, electronic equipment and storage medium

The invention relates to a big data task exception detection method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining starting time, ending time and cycle time of multiple target tasks; obtaining a plurality of target task execution time samples based on the starting time and the period time, obtaining a plurality of target task execution time-consuming samples based on the starting time and the ending time, and meanwhile, introducing the target task execution time-consuming samples into a preset box type algorithm to calculate the execution time samples and the execution time-consuming samples; obtaining a first boundary value of the execution time sample and a second boundary value of the execution time-consuming sample; and obtaining execution time boundary values and execution time consumption boundary values of the plurality of new big data tasks, and respectively determining execution time exception and execution time consumption exception of the pluralit
