Computer system state monitoring method and device

Abstract

The invention discloses a computer system state monitoring method. The computer system state monitoring method comprises the following steps that a virtual state monitoring device is added into a computer; the virtual state monitoring device corresponds to a state monitoring chip connected to a south bridge of the computer, and is driven by an ACPI device drive program; an operation system is informed to generate an abnormal event according to an ACPI method, wherein when the state monitoring chip connected to the south bridge of the computer generates the abnormal event when finding the system state abnormity, the abnormal event is transmitted to the ACPI device drive program according to the ACPI method, and then the ACPI device drive program informs the operation system; the ACPI device drive program obtains the state data processed by the state monitoring chip. The invention further discloses a device with the computer system state monitoring method applied. According to the computer system state monitoring method and device, as the standard ACPI method is used on application software on a system layer and equipment at the bottom layer, transportability, compatibility and reliability of data transmission of the system state are improved.

Description

technical field [0001] The invention relates to state monitoring technology, in particular to a state monitoring method for a computer system and a state monitoring device for a computer system. Background technique [0002] A system in the industrial control industry often has many devices running at the same time, such as acquisition systems, storage systems, video output, keyboard input, and network communication, and the reliability, portability, compatibility, and maintainability of the system have become The main indicator of the industrial control industry, so the status monitoring and control of various system devices has become a necessary means for the reliability of the industrial computer. At present, the commonly used message notification methods for monitoring these information include SMI (System Management Interrupt, system management interrupt), MSI (Message Signaled Interrupt, message signal interrupt), IPI (Inter Processor Interrupt, interprocessor interru...
