There is provided a vibration test device capable of accurately performing self-diagnosis related to the state of the vibration test device, including a failure determination, a failure prediction, and a performance limit determination of the vibration test device. A vibration test device 200 including a shaker 100 configured to shake a shaker table 48, includes: a drive controller 120 configured to control drive of the shaker 100 by controlling current and voltage applied to the shaker 100; a current detector 171 configured to detect the current that controls vibration of the shaker 100; a voltage detector 172 configured to detect the voltage that controls vibration of the shaker 100; a motion detector 135 configured to detect physical quantities related to a motion of the shaker table 48; and a determiner 134 configured to perform a determination related to a state of the vibration test device 200, including a failure determination, a failure prediction, and a performance limit determination, based on detection signals from the current detector 171, the voltage detector 172, and the motion detector 135.

An embodiment of the application provides a cluster service capacity control method, an electronic device, a storage medium and a program product. The method comprises the following steps: obtaining a cluster service request; using a preset control algorithm to perform gradual pressure adjustment processing on the cluster service request, determining target capacity information corresponding to the cluster service request in the case of gradually approaching the performance limit of the device; and performing resource configuration on a terminal device according to the target capacity information, and executing the cluster service request. In this way, the capacity corresponding to the cluster service request can be dynamically adjusted, automatic adjustment of the capacity is realized, and resources are reasonably utilized.
