A remote collector node is an additional cluster node that allows vRealize Operations Manager to gather more objects into its inventory for monitoring. Unlike data nodes, remote collector nodes only include the collector role of vRealize Operations Manager, without storing data or processing any analytics functions.

A remote collector node is usually deployed to navigate firewalls, reduce bandwidth across data centers, connect to remote data sources, or reduce the load on the vRealize Operations Manager analytics cluster.

Remote collectors do not buffer data while the network is experiencing a problem. If the connection between remote collector and analytics cluster is lost, the remote collector does not store data points that occur during that time. In turn, and after the connection is restored, vRealize Operations Manager does not retroactively incorporate associated events from that time into any monitoring or analysis.

You must have at least one primary node before adding remote collector nodes.
