Abstract: A method of monitoring an element in a computer network including monitoring a preselected variable relating to that element; defining a threshold for the monitored preselected variable; establishing a sliding window in time; repeatedly generating a time above threshold value, the time above threshold value being a measure of an amount of time during which the monitored variable exceeded the threshold during the sliding window of time; detecting when the time above threshold value exceeds a condition window value; and in response to detecting when the time above threshold value exceeds the condition window, generating an alarm.

Abstract: A method of tracking the movement of data between data centers through different types of domains is disclosed. Network topologies are dynamically determined and objects corresponding to elements in the domains (entity objects) are stored in a Topology Object Model. The details of the elements stored include both physical and logical connections to other elements in the domain. Elements are cross-referenced with other elements using entity objects associated with the elements. A change in the status of an element is recorded in the corresponding entity object and in the entity objects of the cross-referenced elements. The information contained in the Topology Object Model is graphically presented to a user by displaying depictions of the physical or logical connections and datapaths used in data movement across the multiple domains.
