Abstract
An event analysis system in a network is provided. During operation, the system can determine a set of monitoring elements in the network. A respective monitoring element can facilitate monitoring of events in the network. The system can then represent a respective monitoring element as a node of a graph. If the corresponding monitoring elements are related based on a relationship definition, the system can connect a node pair of the graph with an edge. The system can activate a set of nodes of the graph corresponding to an issue in the network based on notifications from one or more monitoring agents on one or more switches in the network. Subsequently, the system can determine a root cause of the issue by traversing the set of activated nodes of the graph and determine a recovery action for mitigating the root cause.
