Abstract: 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.

Abstract: 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.
