Abstract: The substantially simultaneous tracing/monitoring of a plurality of sets of events via a single network interface. The plurality of events can be traced and/or monitored for one host or for a plurality of hosts coupled via the same network interface. The sets of events to be traced/monitored for a host are defined by the host and maintained in one or more configuration files. The configuration files may be dynamically updated.

Abstract: A system, method and apparatus for enforcing the administration policy of a system. The method can include receiving a request to perform an administrative task directed to a resource within a computing network. Responsive to receiving the request, an administration policy including a set of rules for governing the administrative task can be retrieved as can state data for the resource. Subsequently, the retrieved policy can be applied to the retrieved state data. Consequently, the administrative task can be permitted only if the retrieved state data satisfies the set of rules in the retrieved policy.

Abstract: Monitoring components of a system is provided by associating status of at least one component of the system with one of a set of component independent predefined situation categories to provide the status of the component in a common situation format that includes the associated component independent predefined situation category. Status of the system is analyzed based on the common situation format representation of the component status.

Abstract: Problems are resolved in an application program that runs on an Information Technology (IT) infrastructure that includes IT components. A symptom is generated that identifies a problem in the application program. Selected IT components in the IT infrastructure that may cause the problem in the application program are identified, based on the symptom. Status of the selected IT components is obtained by obtaining a respective situation for a respective IT component. The respective situation is one of a set of component-independent predefined situation categories that is associated with a respective selected IT component. The respective situations provide the status of the selected IT components in a common situation format that includes the associated one of the component-independent predefined situation categories. The respective situations that are obtained are analyzed to identify at least one problem in the selected IT components that may cause the problem in the application program.

Abstract: Methods, systems (apparatus) and computer program products are provided that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter. The control of the data rate may be accomplished by assigning to guaranteed bandwidth connections, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. Guaranteed bandwidth connections are then limited to this amount of data in a time interval. Furthermore, an outbound data threshold for data sent tot he adapter and a total data threshold for data to or from the adapter may be established and best efforts data not sent to the adapter if either of these thresholds are exceeded within the time interval.

Abstract: Methods, systems (apparatus) and computer program products that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter are provided. The data rate is controlled by assigning to the guaranteed bandwidth connection, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. The amount of data transmitted through the communications adapter for the guaranteed bandwidth connection is then counted so as to provide a connection data count associated with the guaranteed bandwidth. Data transmitted for the communications adapter associated with the guaranteed bandwidth connection is not transmitted to the communications adapter if transmission of the data would cause the connection data count to exceed the maximum threshold value assigned to the guaranteed bandwidth connection.

Abstract: Methods, systems (apparatus) and computer program products are provided which control access to a shared resource in a data processing system by predicting utilization of the shared resource based upon historical utilization of the shared resource. Users of the shared resource are then notified of a potential shortage of the shared resource if the prediction predicts that the shared resource will be over-utilized. The prediction may utilize a linear extrapolation to predict future utilization of the share resource. Furthermore, the interval between predictions of the future utilization may be based on time, number of utilization events or a combination of the two.

Abstract: Telecommunications networks require a large number of timers to support the necessary dispatching of tasks. These timers require significant CPU cycles. The present invention describes a method and apparatus for reducing the CPU requirements of timers while maintaining their utility and accuracy by using multi-class periodic timers.
