Abstract
Techniques are disclosed for detection of performance conditions in processing systems. For example, a method of detecting a performance condition in at least one particular processing device of a processing system having a plurality of processing devices includes the following steps. Data is input to a data structure associated with the particular processing device, over a given time period. The input data may be a buffer or a bucket. The input data represents data associated with the execution of at least one function performed by the particular processing device. The given time period includes the time period between consecutive heartbeat signals transmitted by the particular processing device. At least a portion of the input data is removed from the data structure associated with the particular processing device, near the end of the given time period. The removed input data is compared to an expected function execution level. An alarm signal is generated, 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.
