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 in the design objectives of this validated design.

Deploy a 1-node vRealize Operations Manager analytics cluster on an application virtual network. The analytics cluster consists of one primary node with high availability disabled. The 1-node vRealize Operations Manager analytics cluster is still protected by vSphere HA. You save the overhead of using the additional application-based high availability.

Decision ID Design Decision Design Justification Design Implication
CSDDC-OPS-MON-001 Deploy a one-node vRealize Operations Manager analytics cluster. Provides the initial scale capacity that is required for monitoring up to 500 VMs. None.
CSDDC-OPS-MON-002 Deploy one remote collector node. Removes the load from the analytics cluster from collecting metrics from applications. You must assign a collector group when configuring the monitoring of a solution.
