Abstract: A method for optimizing retrieval of node data from network nodes is disclosed. The method comprises obtaining, by a network server via a network, a node data set comprising node data from a plurality of middleware sources, where each of the plurality of middleware sources provides node data about the same network node. The network server is determining a fault in the node data received from one of the plurality of middleware sources, and identifying the middleware source associated with the fault. In response to determining the fault and middleware source, the network server is bypassing the middleware source associated with the fault and retrieving raw node data directly from an element management system associated with the network node.
