Port conflict between BentoML and Grafana prevents dashboard access

Both BentoML and Grafana use port 3000 by default. When running both services on the same host, Grafana fails to start or BentoML service becomes inaccessible, blocking metrics visualization setup.

Change Grafana's default port to avoid conflict. Edit /etc/grafana/grafana.ini, locate [http] section, set http_port to an available port (e.g., 4000), uncomment the line, and restart Grafana with 'sudo systemctl restart grafana-server'. Access Grafana at the new port.
