The invention provides an application network management and control method combining in-band management and out-of-band management of a power grid company, and the method comprises the steps: settingan acquisition server and a client plug-in, enabling the acquisition server to be divided into an in-band acquisition server and an out-of-band acquisition server, and enabling the in-band acquisition server to be accessed to a network in a non-intrusive mode; accessing the out-of-band acquisition server to the network to realize convergence of out-of-band monitoring data and internal monitoringdata, and the client plug-in is installed on a monitored object to acquire performance indexes in real time and integrate the performance indexes with the out-of-band performance indexes to form finalperformance data of the monitored object; and enabling the collected information to enter a server area system, and the server area system monitor and analyze all sessions entering the application and tracks database access actions caused by clicking of the user. According to the monitoring method for monitoring the availability and the performance of each service system in real time from the perspective of the terminal user, faults and hidden dangers of the system can be found in time, and rapid analysis and processing of an information department are facilitated.
