Device and method for adjusting monitoring parameter of WEB service

The invention provides device and method for adjusting a monitoring parameter of a WEB service, aiming at the problem that both monitoring and system performance cannot be considered at the same time in the prior art. The device comprises a parameter collecting module and a control module, wherein the parameter collecting module collects service average response time, processor resources occupied by a system, memory resources occupied by the system and the parameter of a current user visitor volume; and the control module adjusts data intercepting frequency, data processing frequency, data sending frequency and data persistence frequency monitored by the WEB service. The method comprises the following step: when the average response time of the WEB service is changed, adjusting the monitored data intercepting frequency, the monitored data processing frequency, the monitored data sending frequency and the monitored data persistence frequency according to the processor and memory resources occupied by the syste
