The analytics cluster of the vRealize Operations Manager deployment contains the nodes that analyze and store data from the monitored components. You deploy a configuration of the analytics cluster that satisfies the requirements for monitoring the number of virtual machines according to the design objectives of this VMware Validated Design.

Deploy a 3-node vRealize Operations Manager analytics cluster in the cross-region application virtual network. The analytics cluster consists of one master node, one master replica node, and one data node to enable scale out and high availability.

Design Decision

Design Justification

Design Implication


Deploy initially vRealize Operations Manager as a cluster of three nodes: one master, one master replica and one data node.

Provides the initial scale capacity required for monitoring up to 1,000 VMs and provides the ability to scale up with additional data nodes as increased scale requires.

You must size identically all appliances which increases the resources requirements in the SDDC.

Requires manual installation of additional data nodes as per the data node scale guidelines.


Deploy two remote collector nodes per region.

Removes the load from the analytics cluster from collecting metrics from applications that do not fail over between regions.

When configuring the monitoring of a solution, you must assign a collector group.
