Abstract: Disclosed are a method and system for propagating data changes in a hierarchy of dataset models in which each dataset model comprises an analytic and one or more parent datasets, including a primordial dataset. The analytic is executed to instantiate a first instance of the data model. After a change in a primordial dataset, each instance of a dataset model that descends from the primordial dataset is invalidated, and the analytic is re-executed to create a second instance of the data model. Analytical results may be displayed. The first dataset model may include a metric in which the definition of the metric comprises metadata of the dataset model. Metric values may be stored in a first cache, re-computed on a new instance of the dataset model, and stored in a second cache.

Abstract: A method of monitoring in a distributed computer network having a management server servicing a set of managed computers. The method begins by deploying a management infrastructure across a given subset of the managed computers, the management infrastructure comprising a runtime environment installed at a given managed computer. At the given managed computer, the routine executes a monitoring agent in the runtime environment to determine whether a given threshold has been exceeded. Then, a given action is taken if the given threshold has been exceeded. The monitoring agent is executed upon receipt of an external event or as a result of an internal timer. Execution of the monitoring agent involves taking a measurement, comparing the measurement against the given threshold, and then taking some corrective action if possible.

Abstract: A method of managing time expressions for use by applications in a distributed computer network having a management server servicing a set of managed computers. The method begins by defining a set of timers, with each timer preferably comprising an expression of logical operators with a set of one or more primitives as operands. The set of timers is stored in a hierarchical namespace associated with the management server. Preferably, the timers and primitives are stored separately in the hierarchical namespace, with the primitives indexed by name for prompt retrieval.
