In the UI you can see all the agents and their IDs
Then you can so

clearml-agent daemon --stop <agent id>

@<1523701304709353472:profile|OddShrimp85> are you trying to shut down the one running on your machine ?

Nice. That should work. Thanks

Yes. But I not sure what's the agent running. I only know how to stop it if I have the agent id

And the agent continue running.

oh just kill al the processes with clearml-agent in the cmd line

pkill -9 -f clearml-agent

Yup. But I happened to reinstall my server and the data is lost. And the agent continue running.
