Driver Verifier can create log files. These files will contain periodic updates on a number of statistics related to Driver Verifier's actions and the actions of the drivers being verified.
Log files are created from the Verifier utility by using the /log parameter. The frequency of the log record can be specified as well. See Verifier Command Line for details.
Each entry will contain both global counters and individual counters, just as with the verifier /query command.
