Yes — for an ended

FlowRun

, you can get its duration from

flow_run.total_run_time

. Example:

python
duration = flow_run.total_run_time
print(duration.total_seconds())

A few useful details: -

total_run_time

is a

datetime.timedelta

- For a completed flow run, this is usually the best field to use - If you want wall-clock elapsed time instead, you can also compute:

python
if flow_run.start_time and flow_run.end_time:
    elapsed = flow_run.end_time - flow_run.start_time

Difference: -

total_run_time

= accumulated runtime tracked by Prefect -

end_time - start_time

= simple elapsed time between start and finish If you want, I can also show how to retrieve the

FlowRun

first using the Prefect client.
