Abstract:
1. A method for problem determination and diagnosis in a shared dynamic cloud environment during live virtual machine migration, the method comprising: monitoring each virtual machine and each physical server in a shared dynamic cloud environment for at least one metric; identifying a symptom of a problem within the shared dynamic cloud environment and generating an event based on said monitoring, wherein said event corresponds to said symptom; analyzing the event to determine a deviation from normal behavior, wherein said normal behavior is determined based on said monitoring; and classifying the event as a cloud-based anomaly or an application fault based on a comparison of the event with multiple fault signatures, wherein said multiple fault signatures capture a set of deviations from normal behavior associated with (i) one or more cloud-based anomalies and (ii) one or more application faults, and wherein said set of deviations comprises information pertaining to a given virtual machine and a physical server hosting the given virtual machine in the shared dynamic cloud environment, and wherein said classifying comprises: wherein at least one of the steps is carried out by a computer device.
