Remote Collector nodes are a type of vRealize Operations nodes that only gather objects for the inventory, without storing data or performing analysis. Remote Collector nodes can navigate firewalls, interface with remote data sources, reduce the bandwidth across data centers, or reduce the load on the vRealize Operations analytics cluster1. Remote Collector nodes are not part of the analytics cluster, but they are members of the vRealize Operations cluster2.

Data nodes, Primary Replica nodes, and Primary nodes are all part of the analytics cluster and they store data and perform analysis. Data nodes have adapters installed and perform collection and analysis. Primary Replica nodes are replicas of the Primary nodes and provide high availability or continuous availability. Primary nodes are the initial and required nodes in vRealize Operations and manage all other nodes2. References:

 A super metric is a custom metric that you can define using existing metrics and mathematical functions. They allow you to create new metrics that are specific to your environment and can help you gain deeper insights into the performance and health of your infrastructure1. Before enabling a super metric in a policy, you need to associate it to an object type. An object type is a category of objects that share common characteristics, such as hosts, virtual machines, clusters, datastores, etc. By associating a super metric to an object type, you can calculate the super metric for all the objects of that type and display it in the dashboards and reports2. For example, if you create a super metric that calculates the average CPU usage of all the virtual machines in a cluster, you need to associate it to the cluster object type. Then, you can enable the super metric in a policy and apply it to the cluster object or group. This way, you can monitor the average CPU usage of the cluster as a super metric3. References: 1: Configuring Super Metrics 2: Metrics and Properties Details 3: Supercharge Your vRealize Operations with Super Metrics

vRealize Operations provides the following three key benefits within an environment:

• Capacity optimization: vRealize Operations helps you optimize the capacity of your infrastructure and applications by providing visibility, analysis, planning, and automation. You can monitor and forecast the demand, supply, and utilization of resources, identify and reclaim unused or overprovisioned resources, balance the workload across clusters and datastores, and plan for future growth or consolidation scenarios. You can also automate the capacity optimization actions based on policies and alerts.
• Performance optimization: vRealize Operations helps you optimize the performance of your infrastructure and applications by providing real-time and historical metrics, alerts, dashboards, and reports. You can monitor and troubleshoot the health, risk, and efficiency of your environment, identify and resolve performance issues, analyze the root cause and impact of problems, and optimize the configuration and placement of your workloads. You can also automate the performance optimization actions based on policies and alerts.
• Monitoring and troubleshooting: vRealize Operations helps you monitor and troubleshoot your environment by providing comprehensive and integrated visibility across physical, virtual, and cloud infrastructures. You can collect and analyze data from various sources, such as vSphere, NSX, vSAN, Kubernetes, AWS, Azure, etc., and correlate them to provide a unified view of your environment. You can also leverage artificial intelligence and machine learning to detect anomalies, generate smart alerts, and provide recommendations. You can also use various tools, such as dashboards, heat maps, topology maps, logs, etc., to drill down into the details and resolve issues faster.
