Got it! Assuming you’re on Prefect 3.x, the simplest way to suppress logs emitted by the worker process is to raise the logging level via environment variables. Quick options: - Reduce to errors only

export PREFECT_LOGGING_LEVEL=ERROR
prefect worker start -p <your-pool>

- Make the worker essentially silent

export PREFECT_LOGGING_LEVEL=CRITICAL
prefect worker start -p <your-pool>

Notes: - There’s no

--log-level

flag on

prefect worker start

(confirmed via

--help

). - This changes the worker process’s console logs; it does not silence your flow/task logs in the UI. - For Docker/K8s workers, set the env var on the worker container/pod. If you want to target only the worker logger (instead of all Prefect logs), use a custom logging config: 1) Copy the default logging.yml and set the

prefect.workers

logger level to

ERROR

or

CRITICAL

. 2) Point Prefect to it with:

export PREFECT_LOGGING_CONFIG_PATH=/path/to/your/logging.yml
prefect worker start -p <your-pool>
