Embodiment Construction

[0020] The technical solution in this application will be described below with reference to the accompanying drawings.

[0021] figure 1 A schematic flowchart showing a method of the present application, such as figure 1 As shown, method 100 includes:

[0022] Step 110, the monitoring module detects that the first signal of the server jumps, and sends a signal jump indication to the buffer module, the duration of the signal jump indicating signal is at least one clock cycle, and the first signal jump includes a high power The flat signal becomes a low level signal, and the low level signal becomes a high level signal;

[0023] Step 120, the cache module caches the first signal according to the jump indication;

[0024] Step 130, the storage control module stores the buffered first signal into the memory card.

[0025] Specifically, in step 110, all the signals to be monitored of the server are connected to the signal transition monitoring module, which transfers these sign...

Abstract

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 the server.

Description

technical field [0001] The present application relates to the field of computers, and more particularly, to a method and device for storing transition signals. Background technique [0002] During the debugging and use of the server, sometimes problems such as shutdown and downtime may occur due to failures. In order to troubleshoot these problems, debuggers need to know the state of each signal when the fault occurs. [0003] In the prior art, debuggers can use an oscilloscope to monitor corresponding signals, and try to reproduce the fault, and check whether the monitored signal is abnormal when the fault occurs. But this way is inefficient. [0004] A Baseboard Management Controller (BMC) can monitor some important signals and record them in a log, but the important signals it can record are limited. [0005] In addition, in the prior art, there is also a design method in which a server integrates a Microcontroller Unit (MCU) and connects a monitoring signal to the MCU...
