Method and system for actively reporting log information by BMC

Abstract

The invention provides a method and system for actively reporting log information by a BMC (Baseboard Management Controller), and the method comprises the following steps that a BMC unit collects thelog information of each sensor, sends a hand raising request to a CPU (Central Processing Unit) of the BMC unit, and transmits the log information to a predefined log registry after the CPU allows thehand raising request; a diagnosis unit sends out an address parameter of a callback function through the log registry, and returns the address of the log registry to the diagnosis unit as the input of the callback function; the address report log information of the callback function returned by the diagnosis unit is received, so that the diagnosis unit performs corresponding processing accordingto the log information. Based on the method, the invention further provides a system for actively reporting the log information by the BMC. Active reporting of log information is achieved between theBMC unit and the diagnosis unit, information transmission between systems is achieved through RPC communication, active reporting is achieved through a callback function and interruption, and the coderunning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a method and a system for actively reporting log information by a BMC. Background technique [0002] During the development and use of the server, it is necessary to monitor the CPU (Central Processing Unit, central processing unit), memory, hard disk, power supply, temperature, voltage, fan, power consumption, etc. Bmc (Baseboard Management Controller, Baseboard Management Controller) is a key component for detecting and controlling the server. The server diagnosis system needs to obtain error information by reading the Bmc detection log. It is very necessary for the server system to obtain and process Bmc error reports in a timely manner. Currently, Bmc supports passive reading of in-band commands or active reporting through out-of-band snmp. The Bmc in-band command passive reading method requires the app or diagnostic system to repeatedly access the Bmc system a...

This causes polling access to take up more resources, and you may not be able to get the data you want; on the other hand, if you visit at the end of each test item, but some stress tests last for several hours, If the BMC produced the corresponding error log at the beginning, you can only check the result after a few hours, and the real-time performance is not strong enough.
