The invention provides a monitoring method for monitoring system memory database, which is characterized by comprising the following steps: (1) the structure of a monitoring report is defined; (2) a generation module is created for the memory database; (3) a monitoring range is configured through an application interface, and the generation module automatically generates a corresponding monitoring module; (4) a monitoring module is created for the memory database; (5) and the monitoring module generates a monitoring report when monitoring the data change of the memory database, and the application interface publishes the monitoring report and submits the monitoring report to an application program for processing as required. The method can avoid the cost caused by regularly inquiring the memory database, enhance the operation efficiency of the system and monitor the entire database with high efficiency; the monitoring range is configured by the application interface so as to enhance the flexibility; and all monitoring modules can be automatically generated so as to greatly reduce the work load for maintaining the monitoring modules.
