A cloud bridge monitoring method includes the steps that first, a client is set, the client is connected with a cloud server cluster formed two or more cloud servers running a linux operating system through a communication network, partitioned file blocks are stored in the cloud servers respectively, the file blocks are combined to form files corresponding to the file blocks, a foreground detection module is arranged on the client, background detection modules are arranged on the cloud servers, and the cloud servers are further connected through an IB network. The defect that in the prior art, once a problem happens, which cloud server has the problem can not be found in time easily, and the detection effect of the cloud server is influenced is avoided through the subsequent steps of the monitoring method.
