Efficiently monitoring performance counters of a device under test
A recently granted patent (Publication Number: US11868360B2) discloses a method, system, and computer-readable medium for efficiently monitoring performance counters of a device under test (DUT) during high data volume tests. The method involves specifying a time interval of fifteen seconds or less for recording instances of counter values on data planes and control planes. This allows for the persistence of counter values for numerous counters on multiple data streams, creating time series data for correlation at the conclusion of the test. The system includes processors coupled to memory loaded with computer instructions to implement these actions, while the computer-readable medium contains recorded instructions for the same purpose.
Furthermore, the patent details the correlation of asynchronously recorded counters on various data streams according to a time correlation interval, ensuring that counter values with different timestamps are aligned. The system and computer-readable medium also facilitate the correlation of test configuration data and data from external sources with different timestamps based on the correlation interval specified. Notably, the disclosed method and system can handle seventy or more data streams efficiently, making it suitable for high data volume tests where event volumes cannot be recorded at an event level. Overall, the patent aims to enhance the monitoring of performance counters during complex tests by providing a systematic approach to recording, persisting, and correlating data from multiple sources with varying resolutions and time bases.
