Logging method, system and single board management controller

Abstract

The embodiment of the invention discloses a logging method, a system and a single board management controller, wherein, the method comprises the following steps: acquiring time information by a real-time clock chip mounting below a single board management controller; adding a time stamp in operation log according to the time information; and recording the operation log containing the time stamp. The embodiment of the invention also provides a single board management controller and a logging system, solves the management blind area of operation of an out-of-band management network port to lead BMC to conveniently acquire time information when a computer is in hibernation or power off, thereby realizing accurate record of operation logs on the out-of-band management network port.

Description

technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a log recording method, system and single board management controller. Background technique [0002] Intelligent Platform Management Interface (IPMI for short), as a standard applied to server management system design, helps to implement system management on different types of server systems and realize centralized management of different platforms. At present, the IPMI standard has been developed to the latest version IPMI 2.0, in which, by defining the SOL command, the direction of data transmitted by the local serial port during the IPMI session can be changed, the access to the remote server can be realized, and the local area network (Local Area Network; hereinafter referred to as : LAN) is a standard way to remotely view, start, diagnose and repair faults. In IPMI 2.0, secure hash algorithm-1, key-based hash message authentication, and advanced encryptio...

Problems solved by technology

[0003] The inventor found in the process of realizing the present invention that the clock source of the main board of the server in the prior art is only integrated in the south bridge chip, and the single board management controller (Baseboard Management Controller; hereinafter referred to as: BMC) module can only be integrated with the south bridge chip. The chip performs information interaction, and the time information can only be obtained through the Basic Input / Output System (hereinafter referred to as: BIOS) and the operating system, resulting in the BMC module being unable to obtain time information independently; especially when the computer is in a sleep or shutdown state , the BMC module cannot obtain time information at all, therefore, it is impossible to accurately record the operation log of the out-of-band management network port
