Disclosed is a system for changing or assessing the performance of node devices. A first device in communication with the node devices, sends to a node device predicates specifying a test to be made by the node device on its operational state and the node sends the resulting test data back to the first device. Also disclosed, is a system in which a first device sends data to nodes specifying conditions to be fulfilled in the node or the environment, the node testing for the conditions and sending back specified data when the conditions are fulfilled. Also disclosed is a method of debugging a node device by sending a predicate that defines a state to be tested, the device then sending back test results. Also disclosed is a method of debugging a node following a trigger event, in which the content of a memory stack is recorded, and a predicate causes the node to check the memory stack for similar content, and to generate a warning if similar content occurs. |
