Abstract: The invention relates to a method implemented by computer for arbitration between computer programs seeking to access a shared resource concurrently and each transmitting an access request. The method performs time-division multiple access according to which the time is divided into time slots, each of which is allocated to a critical program for access to the shared resource, each time slot comprising a plurality of time units. The method exploits a processing slack associated with each critical program in order to delay a processing deadline for an access request transmitted by the critical program. The method comprises, for each unit time, a step of selecting a waiting access request and a step of determining authorization for immediate processing of the selected access request.

Abstract: Techniques to correlate event data are disclosed. In various embodiments, an aggregation engine is used to correlate event data received from one or more source systems based on one or more correlation rules. An event group comprising at least a portion of said correlated event data is generated programmatically and is asserted as a fact in a working memory of a Rete engine configured to apply one or more Rete rules to facts in the working memory.

Abstract: Methods, program products, and systems implementing adaptive data transmission are disclosed. A universal data collector can act as an intermediary between a log producer and a log processor. The universal data collector can be connected to the log producer through a first, reliable network. The universal data collector can be connected to the log processor through a second, less reliable network. The universal data collector can perform a multi-phase commit of data to ensure that the log data are saved by the log processor. The universal data collector can smooth the data transmission from the universal data collector to the log processor through a network, including adaptively buffering the log data according to available network bandwidth of the network.

Abstract: The invention relates to a method for monitoring at least one message, each message being associated with an action generated by at least one element or user of an information system (1000), said message(s) being collected by at least one message collecting device of the IS. According to the invention, the method comprises the step of defining a plurality of reference event categories each associated with at least one reference action from an ontology based on an intention class that characterizes the purpose of each reference action, an activity type class that qualifies the nature of each reference action, a movement class that characterizes the means for implementing each reference action, a target class that characterizes the object of each reference action, and a gain class that characterizes the result of each reference action.
