To retain monitoring functionality when a disaster occurs, the design of vRealize Operations Manager supports failing over a sub-set of the components between regions. Disaster recovery covers only the analytics cluster components, including the master, replica and data nodes. The region-specific remote collector nodes remain in the affected region.
When a disaster occurs, you use Site Recovery Manager and vSphere Replication for orchestrated recovery of the analytics cluster. You do not recover the remote collector nodes. Remote collector pairs only collect data from local components, such as vCenter Server and NSX Manager, which are also not recovered during such an event. See Recovery Plan for Site Recovery Manager and vSphere Replication for more details.
