Embodiments of the invention provide a method, system and computer program product for log file reduction according to problem space topology. A method for log file reduction according to problem space topology can include receiving a fault report for a fault in a solution executing in memory of one or more computers of a computer data processing system. The method further can include extracting references to at least two resources of the computer data processing system from the fault report. The method yet further can include filtering a set of all log files for the computer data processing system to only a subset of log files related to the at least two resources. Finally, the method can include displaying the subset of log files in a log file analyzer.

Techniques are provided for service placement on hosts for a consumer based on geographic location The techniques include: determining a geographical location of a consumer; and inputting a topology model of an environment including multiple candidate hosts to support a service required by the consumer, the topology model including: a geographic location of each of resource in the environment; and connectivity details between the resources and between the resources and the consumer. The techniques also include: specifying bounding requirements for a host and/or bounding requirements for a path between the consumer to a host; calculating the distance from a candidate host to the consumer; determining if bounding requirements are met by a candidate host; and ordering candidate hosts that meet bounding requirements by distance.

Provided are systems, methods and computer program products that proactively manage configurations that enable a service. Configurations that are critical to enabling a particular service are automatically captured, for example as part of a provisioning activity, and/or tracked in association with that service. This automated, service-oriented configuration management enables improved service assurance and faster identification of problems, and mitigates the problem of errors and compromised service delivery that can arise from misconfigurations.

Managing network configurations

Embodiments include methods of topology discovery in a virtual environment. Aspects include tracking change events, responsive to a change event, rediscovering dependencies between devices in the virtual environment and maintaining a dependency mapping between the devices. Aspects also include, responsive to a fault event, building a first topology model of the virtual environment and generating a first set of the devices which the first topology model is dependent on. Aspects also include, responsive to a resolution event, building a second topology model and generating a second set of the devices which the second topology model is dependent on. Aspects further include generating a fault device set by combining the first set and the second set, deleting any duplicate devices, and utilizing the generated fault device set to determine which of the devices are more likely to be associated with future fault events.

Temporally classifying and visually representing network and IT infrastructure with planned or occurred configuration activities and/or policy compliance or non-compliance of network and IT resources, including a method, apparatus and computer program for gathering and classifying observable configuration aspects of resources and relationships in a network of resources, wherein the method comprises: analyzing the network of resources to collect planned configuration times and actual resource status; monitoring actual resource status to make determinations if planned configurations are executed; and updating a network configuration status with the determinations. Planned and actual configurations are collected and monitored over a defined time range extending before and/or after a time zero. Each planned or actual configuration is categorized with respect to one or more time windows in the defined time range.

Network resource configurations

Methods, apparatus, and products for inferred discovery of a data communications device connected to a router, unreachable by a management module, and characterized by a device address are disclosed that include querying, by the management module, the router for connection data and identifying, by the management module in dependence upon the connection data, the device address.

Inferred discovery of a data communications device

Network management data is managed by determining that a first version and a second version of a set of network management data have been created. The set of network management data is associated with a plurality of managed entities in a network. First and second network graphs are created based on the first version and second version of the set of network management data, respectively. The first and second network graphs include a first and second set of entities in the plurality of managed entities, respectively. A similarity metric is assigned between at least one or more entities in the first and second set of entities. At least a first entity in the first set of entities and at least a second entity in the second set of entities are determined to be identical entities based on the similarity metric being one of equal to and above a first given threshold.

Reconciling network management data

A linkage controller analyzes, for a first management application managing at least one common resource with a second management application adjacent to the first management application within a computing environment comprising multiple resources and relationships, a resource and relationship model known by the first management application of a selection of resources and relationships managed by the first management application from among the plurality of resources and relationships in the computing environment. The linkage controller identifies, for the first management application, only a minimal set of resources and relationships within the resource and relationship model providing at least one optimal linkage point between the first management application and the second management application as to the at least one common resource. The linkage controller outputs the minimal set of resources and relationships to the second management application for relating to the first management application.

Efficiently relating adjacent management applications managing a shared infrastructure

A method, system and computer-usable medium are disclosed for suppressing managed endpoint (MEP) child events in a network. A MEP multicast message is broadcast by an originating MEP. Responses received from peer MEPs within a selected time interval are processed to determine their respective IP address, MAC address, and VLAN. If this information is not currently stored in a table of peer MEP device information associated with the originating MEP, then it is added. The responding MEP is then marked in the peer MEP device table as having responded. Peer MEP devices that have responded to previous multicast messages, but have now failed to respond within the selected time interval, are determined. A MEP network event is generated, comprising the IP address of the device containing the MEP, the MAC address for inward-facing MEPs, the MAC address of the associated bridge, the port addresses for outward-facing MEPs, and associated VLAN information. If another MEP network event occurs, the MAC address of the MEP and its VLAN information is determined. If the VLAN associated with the current MEP network event contains a MAC address associated with a prior MEP network event, then the MEP network event is designated as a child MEP network event and suppressed. Otherwise, the MEP network event is designated as a parent MEP network.

System and method for correlating carrier ethernet connectivity fault management events

A method, apparatus, and computer program product for discovering network paths between network devices in a distance-vector network are provided. The method may include providing a node model of network devices in a distance-vector network. The node model may include a network address corresponding to a network device. The network address may be used to query the network device for routing information. This routing information may be used to identify another network address corresponding to a second network device, and to identify a path from the first network device to the second network device. These devices and the path therebetween may be mapped in the node model. Finally, the second network device may be queried for subsequent routing information to identify and map subsequent devices and paths.

Method, apparatus and computer program product for correlating performance events in a data processing system. A first event is received at one of a first device and a second device of the data processing system, and a second event is received at one of the first device and the second device. A type of a connection between the first device and the second device is identified to form an identified type of connection, and a relationship between the first event and the second event is determined based on the identified type of connection between the first device and the second device.
