The invention particularly relates to a method for supporting the realization of sensor information collection by increasing a custom command. According to the method for supporting the realization of the sensor information collection by increasing the custom command, a sensor collection thread is added to an IPMI protocol stack of SMC, and support of the custom command is added to the IPMI protocol stacks of BMC of computing units; the sensor collection thread generates no direct communication with a Message Handler, a function of the custom command can be called by an index through a command mapping table provided by the Message Handler of the BMC, so that the IPMI protocol stack of the SMC has the functions of an IPMI Server and a IPMI Client, and the SMC is applicable to the information collection of a senor of a server having a plurality of computing units. According to the method for supporting the realization of the sensor information collection by increasing the custom command, on the basis of the realization of the IPMI protocol stack, the IPMI protocol stack of the SMC can have the functions of the IPMI Server and the IPMI Client by few changes, and the method is suitable for the information collection of the senor of the server having the plurality of computing units.
