摘要:
Method, apparatus and computer program product are configured to perform computer monitoring activities; to collect information regarding computer system status during the computer monitoring activities; to detect a problem in dependence on the information collected during the computer monitoring activities; and to determine whether to launch a diagnostic probe when the problem is detected. The monitoring activities may be performed on a periodic or event-driven basis. The determination whether to launch a diagnostic probe is based on a rule included in a hierarchy of rules. The hierarchy of rules is based on problem tickets; system logs; and computer system configuration information.
摘要:
Problem ticket usage is improved by adding dynamic information to the ticket or using dynamic information to prompt the user or customer for additional information. Two categories of dynamic information are used. In the case where an initial problem ticket involves identification of a problem component the dynamic information is derived from abnormal status of related components, such as components which support the problem component. In the case where an initial problem ticket involves problem symptom information, data is derived from resolved problem tickets by identifying important words or concepts which are stored in connection with the particular symptom. When later problem tickets having the same symptom are identified the related important words or concepts are either added to the problem ticket or are used to prompt customers or users for additional information. A system implementing an embodiment of the invention is also described.

Method, apparatus and computer program product manage a plurality of networks with a single tenant network management tool using virtualization and implement control plane virtualization of the single tenant management tool; data storage virtualization of a data storage apparatus and network address virtualization of an available address range. A virtual machine may be implemented for each network of the plurality of networks to contain an instance of the single tenant management tool. In one implementation, a proxy is used to implement data storage virtualization. In another implementation, separate data storage is maintained for each network and data storage virtualization is achieved by managing the network protocol stack virtualization. The network address virtualization may be implemented using machine-level virtualization or operating-system-level virtualization.

摘要:
A method (and system) for managing a distributed-memory parallel application running on multiple servers, includes dynamically moving a plurality of executable program components, where each of the plurality of executable program components are running on one of a plurality of virtual machines, using migration of the virtual machines between physical servers. The load balancing is operated based on a workload of each of the virtual machines and servers, where a virtual machine, or a plurality of virtual machines, are transferred to balance the workload between each of the servers.

In one embodiment, the present invention is a method and an apparatus for bandwidth efficient distribution of content over a computer network. In one embodiment, a server cooperates with clients to reduce the usage of server bandwidth, thereby reducing bandwidth-associated distribution costs. The server controls the way that content is distributed within the system, and the clients/receivers may act as intermediate forwarders of data packets. In one embodiment, this is accomplished by sending data items to a first group of receivers on a packet-by-packet basis using unicast communication. The first group of receivers then sends the packets on to a second set of receivers, and the process continues until the packet is forwarded to all intended receivers.

An exemplary method of determining a set of optimal solutions for a problem includes the steps of determining a set of probable solutions for the problem; presenting the set of probable solutions to at least one human expert; receiving at least one selection by the at least one human expert of at least one solution from the set of probable solutions; and determining a set of optimal solutions from the set of probable solutions based at least in part on the at least one selection by the at least one human expert. The method may also include steps of presenting at least one of the set of probable solutions and the set of optimal solutions to at least another human expert; permitting the at least another human expert to select at least one solution from at least one of the set of probable solutions and the set of optimal solutions; and determining a set of optimal solutions from the set of probable solutions based at least in part on the at least one selection by the at least one human expert and the at least one selection by the at least another human expert.

A method is provided. The method includes the steps of: generating a model of an information technology process, wherein the process comprises a plurality of process steps and wherein the model identifies resources associated with the process; identifying dependencies on the resources for at least one process step of the plurality of process steps; perturbing the model; assessing an impact of the perturbation on the model; and reducing the impact of the perturbation on the model by utilizing at least one remedial action.
摘要:
The use of multi-homing to multiple network providers to improve performance of network applications is disclosed. In accordance with the present invention, a general purpose computer performs primary route control functions, without requiring a special route control device. Route selection is made in accordance with desired metrics which may include relevant to performance, availability, or cost.
