The invention provides a process exception monitoring method and device, which relate to the technical field of software. The method comprises the following steps that a business process module sendsa keep-alive message to a monitoring module in a normal running period; when the monitoring module does not receive the keep-alive message sent by the business process module within the preset time length, the monitoring module processes the message according to a preset processing rule corresponding to the process exception, and the preset time length is longer than the period of the business process module sending the keep-alive message. In this technical scheme, it is not necessary to rely on the abnormal exit of the process to monitor whether the process is abnormal or not, and it is morecomprehensive and efficient to monitor the process exception.
