How to remove Sensu-go-agent completely from the system

Sensu Go
1

Hi,
How can I remove sensu from a Ubuntu or Debian system?
I ran apt remove --purge sensu-go-agent but I still have some folders and the service running

Thanks

Hey there, an apt purge should be completely removing the Sensu bits from the system. Since it’s not, here are the default paths for the agent and the backend:

Backend

Removing all of those files should completely purge Sensu from your system.
