Modern network devices like routers offer thousands of operational counters. All of them could be important for network monitoring, though their high number makes this process infeasible, often resulting in only a small subset of the counters to be considered for further interpretation and processing. This demo paper showcases the practical use of an unsupervised multivariate online detector, DESTIN [1], which could assist an operator in automatically monitoring all or at least a very large number of counters and exploring inter-dependencies between them to further the operator's understanding of the state of the network. DESTIN can detect changes in the network without any need for predefined KPIs on the router itself.
