The present invention relates to a system and method for monitoring multi-domain network using end-to-end layered visualization to identify exact root cause of network element to prevent degradation in the network performance is disclosed. The system comprises of data collection module, correlation module, mapping module and management server. The data collection module collects performance data, alarm data, configuration logs and signalling traces from one or more network elements through the management server to draw connectivity across one or more layers. The correlation module correlates the collected performance data, alarm data and configuration logs at regular intervals in order to isolate the root cause of the issue identified. This correlated data of all the network elements are superimposed with layered visualization and mapped by the mapping module and thereby identify the exact root cause of network element causing degradation in the network performance.
