Some questions about measurements

[OhhhhPi]

Hi, sorry to bother you. I'm learning hotstuff and want to see the difference in latency and throughput when leader-rotation is different. But when I ran the code with the command ./hotstuff run --output "D:\testResults" --metrics "throughput","client-latency" . I didn't see the latency and throughput data or LatencyMeasurementEvent in output file. How can I see the measurement data?
Below is the output file.

You need to specify a measurement interval with the “—measurement-interval” flag. It is not enabled by default and thus no measurements are recorded.
