In one embodiment, a device obtains testing parameters used by a plurality of agents in a network to perform testing with respect to an online application. The device identifies overlapping parameters among the testing parameters and generates a consolidated set of testing parameters for the overlapping parameters. The device configures the plurality of agents such that a singular testing agent performs testing with respect to the online application using the consolidated set of testing parameters instead of multiple testing agents performing testing with respect to the online application using the overlapping parameters.
