BMC and device monitoring method and device thereof, and readable storage medium

Abstract

The invention discloses a device monitoring method for a BMC (Baseboard Management Controller). The device monitoring method comprises the following steps: acquiring an over-limit signal sent by a monitoring device; according to the overrun signal, reading monitoring data in the monitoring device; according to the monitoring data and a monitoring threshold value of the monitoring type device, determining an over-limit event of the monitoring type device; wherein the over-limit event comprises an over-high event and / or an over-low event; according to the invention, by acquiring the overrun signals sent by the monitoring devices and utilizing the hardware resource advantages of the monitoring devices, the work of capturing the events exceeding the limit value is realized by the monitoring devices at the bottommost layer, so that the asynchronous IO replaces the existing polling scheme, and the monitoring devices are accurately monitored in real time; the scheduling pressure of the BMC is relieved, and the system process response speed is guaranteed; the invention further discloses a device monitoring device of the BMC, the BMC and a computer readable storage medium, which also have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a BMC device monitoring method, device, BMC and computer-readable storage medium. Background technique [0002] BMC (Baseboard Manager Controller, Baseboard Management Controller) is an essential functional component in network infrastructure such as servers and switches. Its main functions include real-time monitoring of health information such as temperature, voltage, current, power consumption, and fan speed in the hardware environment. . Among them, information such as temperature, voltage, current, power consumption and fan speed are collected from different types of monitoring devices, such as temp sensor (temperature sensor), ADC (analog to digital converter, analog-to-digital converter) and VR (Voltage Regulator , voltage regulator) and so on. [0003] In the prior art, BMC adopts polling mode (such as single-thread polling or multi-thread polling) for the monitoring...

Problems solved by technology

However, the polling method consumes a large amount of clocks, which reduces the response rate of other business processes and affects the user experience; and single-threaded polling will not be able to capture the situation that a single device exceeds the limit in time, and multi-threaded polling will cause memory loss. high occupancy problem
