A networked computing system for reporting software events occurring on a client computer to a collection service is presented. The networked computing system comprises a collection service, communicatively coupled to a communications network, and a plurality of client computers. The collection service is configured to receive software events from a client computer over the communications network. Each client computer is also communicatively coupled to the communications network. Each client computer is further configured to generate a sampling value on the client computer for a corresponding software module, and detect the occurrence of a software event corresponding to the software module. Upon detecting the occurrence of a software event corresponding to the software module, each client computer determines whether a sampling value falls within a predetermined sampling range, and if so, reports the software event to the collection service over the communications network.
