When you run the transaction counter during a Benchmark Run with Jobs enabled, HammerDB will automatically record the transaction count as part of the Job. HammerDB also provides the option to log the output of the transaction counter to a separate logfile. This enables the recording of transactions throughout the test that can be used to verify the transaction rate across time. To enable transaction counter logging select Log Output to Temp. There are also options to use a unique log name and to generate timestamps. With the following options selected.

Figure 6.13. Log Transaction Counter Output

The following output in a logfile called hdbtcount.log will be produced in the defined temporary directory.
