A computerized service including interconnected components within a computer network is monitored using entry points of a service model corresponding to the computerized service. A discovery process is performed by a discovery mechanism based on an initial entry point of a computerized service. A service model is generated based on results of the discovery process. The service model includes indications of a plurality of components of the computerized service and indications of a plurality of entry points including the initial entry point and at least one additional entry point used for communication between ones of the plurality of components. Using a monitoring mechanism, at least one entry point of the plurality of entry points is tested using at least one protocol associated with the at least one entry point.
