 When you're done with the data, you can run `docker compose down` which will completely delete and remove the monitoring stack.

+Make sure you destroy your old environment and pull in the new stack to upgrade and fully restart.

+If you installed via git:
+```
+docker compose down

+`FRM_HOSTS`: A comma separated list of Ficsit Remote Monitoring servers. If protocol is unspecified, it defaults to http. EG: `http://myserver1.frm.example:8080,myserver2.frm.example:8080,https://myserver3.frm.example:8081`
