In one embodiment, a method for monitoring operation of a device is provided. Monitoring of the device at a source using a gateway is activated. The device is coupled to the source to receive power from the source for operation of the device. The gateway monitors an electrical characteristic of the source coupled to the device. Monitored information of the electrical characteristic is captured from the source when an event occurs at the device. The monitored information is correlated as being associated with the device. The monitored information is used in an analysis to analyze whether a variance in the monitored information violates a threshold to trigger an indication of a problem in the operation of the device.
