The invention relates to a lightning arrester monitoring device. The lightning arrester monitoring device comprises a first sensor which is arranged at a grounding lead of a lightning arrester and is used for collecting leakage current; the leakage current processing module is connected with the first sensor; the preprocessing module is used for preprocessing leakage current collected by the first sensor; the second sensor is arranged on a grounding lead of the lightning arrester and is used for collecting lightning pulses; the pulse processing module is connected with the second sensor; the preprocessing module is used for preprocessing lightning pulses collected by the second sensor; and the controller is respectively connected with the leakage current processing module and the pulse processing module, and is used for receiving the preprocessed leakage current and the lightning pulse, outputting a leakage current effective value according to the preprocessed leakage current, and outputting a lightning strok
