Some embodiments provide a method that provides a visualization of data message paths through sets of services. For each data message of multiple data messages that traverse a network, the method identifies a set of services applied to the data messages within the network based on flow data collected from a set of network elements. The method generates an animated visualization of the data messages that includes representations of the services and paths the data messages take through the services. The method provides the generated visualization in a graphical user interface (GUI) to enable monitoring of data messages traversing the network via different service paths.
