Method of storing jumping change signal and device thereof

The application provides a method of storing a jumping change signal. The method includes: detecting a jumping change of a first signal of a server by a monitoring module, and sending a signal jumpingchange indication to a buffer module, wherein duration of the signal jumping change indication signal is at least one clock cycle, and jumping changes of the first signal include a change from a high-level signal to a low-level signal and a change from the low-level signal to the high-level signal; caching the first signal by a cache module according to the jumping change indication; and storingthe cached first signal to a storage card by a storage control module. Therefore, according to the method provided by the embodiment of the application, the jumping change signal of the server can beeffectively stored, detection and storage on key signals are realized, and when the server fails, the jumping change signal stored in the card can be stored simply and quickly to carry out analysis torealize troubleshooting of
