Delete GRMG Monitoring

I recently setup GRMG monitoring for UDC and Availability Monitoring to see if it provided the level of monitoring we need. As of now, we do not want to use GRMG, so I need to delete the setup. I have deleted the scenarios from transaction GRMG from our CEN and also from the local SAP system but it is still monitoring. Does anything else need to be removed, do the systems need to be restarted etc to completely delete the GRMG configuration?

Thanks in advance for any advice provided.

Regards,

Scott
