Claim 0:
1. A method of efficiently monitoring performance counters of a device under test (DUT) during a high data volume test having data event volumes that cannot be recorded at an event level, the method including:
specifying a time interval of fifteen seconds or less for recording instances of counter values on data planes and control planes;
using the time interval during a test of the DUT to control persisting an instance of the counter value for each of numerous counters on numerous data streams and to create numerous time series data of the instances from the counters, allowing recording of counters that have a higher resolution than the time interval, of counters that have various resolutions and time bases and of counters from different sources asynchronously at different times;
at a conclusion of the test, correlating, using a correlation interval that is greater than or equal to the specified time interval, the numerous time series data that have the various resolutions and time bases with test configuration data about a test state in the correlation intervals; and
correlating data from external sources that also have imperfectly synchronized time bases.
