The invention provides a hardware monitoring system applied to a unix-like system. The hardware monitoring system comprises an operation system acquisition module and an IPMI acquisition module whichare respectively connected with a disposal alarm module. The operating system acquisition module runs in an operating system in the form of a system toolkit, and calls hardware state data through theoperating system. The IPMI acquisition module is arranged on an external board card, is connected with computer device through an IPMI protocol and acquires hardware state data. The operating system acquisition module and the IPMI acquisition module upload the acquired hardware state data to the disposal alarm module in real time. And the disposal alarm module compares the received hardware statedata with a preset threshold value and gives an alarm for abnormal data. Through automatic system acquisition, the monitoring acquisition data granularity can be greatly improved, and the acquisitionalarm precision is enhanced. Real-time hardware-level monitoring can be realized, and the problems of repeated labor, untimely discovery and the like of manual inspection can be solved.
