Embodiments of the present invention relate to method and apparatus for system problem diagnosis and recovery. According to embodiments of the present invention, problem symptom information in a system can be automatically monitored and collected BY a monitoring apparatus (or referred as to 'agent') deployed at the system side. Upon after receiving such information, the diagnosis apparatus, for example, may automatically determine a root cause of the problem by querying a backend knowledge repository, and possibly generate an executable software package for recovering the problem. If the diagnosis apparatus determines that the currently available information is insufficient to determine a creditable enough root cause and/or is insufficient to generate the software package for recovering the problem, the diagnosis apparatus may interactively control the monitoring apparatus to collect desired additional information. In this way, the efficiency and accuracy of problem diagnosis and recovery may be improved.

A request is obtained at a monitoring controller to provide a monitoring function for at least one subject virtual processing element (e.g., VM) in a virtualized information processing system. The monitoring controller selects and/or provisions at least one traffic capture appliance configured to capture traffic associated with the subject virtual processing element. The monitoring controller requests the virtualized information processing system to forward a copy of traffic associated with the subject virtual processing element, using traffic mirroring and an encapsulated tunnel, to the traffic capture appliance for analysis.

A data classification system is associated with a hybrid cloud comprising at least one private cloud and at least one public cloud. The data classification system comprises a data set classification model classifying data sets, a cloud classification model classifying the private and public clouds of the hybrid cloud, and mapping policies each specifying a particular mapping between one or more classes of the data set classification model and one or more classes of the cloud classification model. The data classification system classifies a received data set using the data set classification model, and determines for the received data set at least one cloud of the hybrid cloud to which the received data set should be directed for further processing based at least in part on a result of the classification of the received data set, the cloud classification model and a selected one of the mapping policies.
