  • Anomaly detection method for the virtual machines in a cloud system
    Patent number: 10616268
    Abstract: An anomaly detection method for virtual machines in a cloud system, in which an HsMM is trained by searching the state information of the normal virtual machines in the cloud system, and a corresponding algorithm is designed to detect and calculate the probabilistic logarithm probability and the Mahalanobis distance of the dynamic changing behaviors of the resources in the cloud system when each virtual machine is online. If the Mahalanobis distance value of an online virtual machine is detected being higher than the preset threshold value of the cloud system, it is suggested that the virtual machine is operating anomalously.

  • AN ANOMALY DETECTION METHOD FOR THE VIRTUAL MACHINES IN A CLOUD SYSTEM
    Publication number: 20180309770
    Abstract: This invention relates to an anomaly detection method for the virtual machines in a cloud system, in which an HsMM is trained by searching the state information of the normal virtual machines in the cloud system, and a corresponding algorithm is designed to detect and calculate the probabilistic logarithm probability and the Mahalanobis distance of the dynamic changing behaviors of the resources in the cloud system when each virtual machine is online. If the Mahalanobis distance value of an online virtual machine is detected being higher than the preset threshold value of the cloud system, it is suggested that the virtual machine is operating anomalously. Moreover, an anomaly detection and treatment system in the cloud system will start to detect and treat the anomaly of the virtual machine.
