摘要： A method, system and computer program product for adaptive system monitoring. In one embodiment, the method comprises generating time-varying correlation graphs indicating correlations between a multitude of parameters of the system, and using the correlation graphs to identify monitoring logic for monitoring the system. In an embodiment, the correlation graphs are used to select a group of the parameters as monitoring parameters, and these monitoring parameters are dynamically changed. In one embodiment, the monitoring parameters form sets of monitoring parameters, and each set of monitoring parameters is used to monitor the system for an associated period of time. The lengths of these monitoring periods are changed based on the rate of change of the correlation graphs. In an embodiment, the rate at which the monitoring parameters are changed is itself changed based on the rate of change of the correlation graphs.

摘要： Various embodiments estimate network load in a wireless communication network. In one embodiment, at least one call detail record associated with a wireless communication network is received. A topology representing the network is analyzed. The topology includes a plurality of nodes each representing a network element within the wireless communication network. The topology also includes a plurality of edges between two or more of the plurality of nodes. Each of the plurality of edges indicates that the two or more plurality of nodes are communicatively coupled to each other within the network. A set of paths is identified between two or more nodes in the plurality of nodes corresponding to a set of call flow information within the at least one call detail record. A state of each network element represented by the two or more nodes in the set of paths is determined based on the call detail record.
