[Observium] Procedure to add a MIB file for a device already monitored by Observium

Hello,

I put a MIB file in /opt/observium/mibs/ for a device whose interfaces I already monitor with SNMP. In order to have Observium uses the MIB to monitor all its components do I just run "/opt/observium/discovery.php -h new" again or do I have to modify "config.php" then run "/opt/observium/discovery.php -h new"? Thanks!
