Arrangement and a method relating to performance monitoring

Abstract

The present invention relates to an arrangement for monitoring performance in a network comprising a number of network devices or nodes, services and users, in real-time. The arrangement comprising information collecting means, generating means for generating performance KPI indicators depending on a number of definition performance parameters for one or more of said network nodes. The generating means comprise or communicate with decision graph generating means adapted to generate decision graph structures representing respective KPI values and combination probabilities in dependence of KPI definition performance parameters and in dependence of additional or correlation parameters. The generating means comprise decision graph content updating means adapted to update the decision graph structure or structures using said collected information to enable prediction of KPI status/behavior and message sending means are provided which are adapted to send out messages or notifications relating to one or more prediction results.
