The invention discloses report information obtaining method, device, equipment and system, and belongs to the technical field of a computer. The method comprises the following steps that in the application program executing process, whether key function points pre-specified in a key function item in an application program are abnormal or not is detected; if the abnormality occurs, the abnormal information for indicating that abnormality occurs in the key function points in the key function item is obtained; the report information is sent to a server, wherein the report information includes the abnormal information. When the condition that a certain key function item in the application program generates abnormality is detected, the reporting information including the abnormal information is sent to the server; the problem of low maintenance efficiency on the stability of the key function item of the application program in the prior art is solved; and the effect of greatly improving the maintenance efficiency on the stability of the key function item of the application program is achieved.
