Abstract: An automated solution for measuring the performance of one or more selected apps across a wireless network, from a given location. The device of the invention, which may be termed a ‘probe’, performs the automation and validation of a range of apps with their respective cloud services, the probe including a local interface for receiving from a remote controller the credentials intended for testing the target app service if applicable. The invention can be used to generate an alert when the performance of a particular app at the location fails to meet certain criteria. It can also be sued to generate a report relating to the app performance at the location.
