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 3-node vRealize Operations Manager analytics cluster in the cross-region application virtual network. The analytics cluster consists of one primary node, one primary replica node, and one data node to enable scale out and high availability.
|Decision ID||Design Decision||Design Justification||Design Implication|
|SDDC-OPS-MON-001||Deploy vRealize Operations Manager as a cluster of three nodes: one primary, one primary replica, and one data node. Use this deployment to monitor Region A and Region B.||
|SDDC-OPS-MON-002||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.||You must assign a collector group when configuring the monitoring of a solution.|
|SDDC-OPS-MON-003||Apply vSphere Distributed Resource Scheduler (DRS) anti-affinity rules to the vRealize Operations Manager analytics cluster.||Using vSphere DRS prevents the vRealize Operations Manager analytics cluster nodes from running on the same ESXi host and risking the high availability of the cluster.||
|SDDC-OPS-MON-004||Apply vSphere Distributed Resource Scheduler (DRS) anti-affinity rules to the vRealize Operations Manager remote collector group.||Using vSphere DRS prevents the vRealize Operations Manager remote collector nodes from running on the same ESXi host and risking the high availability of the cluster.||
