1. A method for generating a model of network application health, the method comprising: receiving activity data that corresponds to activities of a plurality of applications that are operable to execute on at least one networked device; combining received activity data by removing redundant portions thereof and by reconciling inconsistencies among data received from different ones of the plurality of collector applications therein, wherein after combining the received activity data, the received activity data includes the activity data from the plurality of collector applications without redundant portions thereof; identifying ones of the plurality of applications and relationships there between based on the received activity data; generating a model including identified applications and relationships there between; and displaying a representation of the model; wherein receiving activity data, combining received activity data, identifying ones of the plurality of applications and relationships therebetween, generating a model, and displaying a representation of the model comprise operations performed using at least one programmed computer processor circuit.
