Abstract:
1. A method of detecting a performance condition in at least one particular processing device of a processing system, wherein the processing system comprises a plurality of processing devices, the method comprising the steps of: inputting data to a data structure associated with the particular processing device, over a given time period, the input data representing data associated with the execution of at least one function performed by the particular processing device, and the given time period comprising the time period between consecutive heartbeat signals transmitted by the particular processing device; removing at least a portion of the input data from the data structure associated with the particular processing device, near the end of the given time period; comparing the removed input data to an expected function execution level; and generating an alarm signal, when warranted, based on the comparison of the removed input data to the expected function execution level such that a performance condition in the particular processing device is determinable.
