Cloud Proxies are special types of remote collectors that enable vRealize Operations Cloud to collect and monitor data from on-premises data centers. Cloud Proxies establish a one-way communication channel from the on-premises environment to the vRealize Operations Cloud, and they securely upload data to the cloud instance without requiring any inbound ports to be opened on the firewall.Cloud Proxies can support multiple vCenter Server accounts and other management packs, and they provide data persistence and high availability features12.References:1:Configuring Cloud Proxies in vRealize Operations2:Managing Cloud Proxies in vRealize Operations

To discover custom application services running on virtual machines, the administrator needs to install the vRealize Operations Service Discovery Management Pack1.This management pack enables service and application discovery using the Service Discovery adapter, which leverages the Telegraf agent to collect data from the end point VMs2.The administrator can configure the Service Discovery adapter to discover predefined and custom applications and services, and view their relationships and metrics in vRealize Operations3. The administrator can also create custom application definitions based on object names, tags, or properties, and import them as XML files.Configuring a white list is not a valid option, as it is used to filter out unwanted services from discovery.References:1: vRealize Operations Service Discovery Management Pack - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.6/com.vmware.vcom.core.doc/GUID-B9095E9B-7F10-4B2F-95A9-3D54CF5038FF.html)2: Service and Application Discovery - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.10/com.vmware.vcom.core.doc/GUID-CC683117-D936-432C-B30B-CCCA08E863FB.html)3: Configure Service and Application Discovery - VMware Docs(https://developer.vmware.com/apis/579/vra-advanced-designer/) : Create Application Definition - VMware Docs : Configure White List - VMware Docs

The generate passphrase option allows the vRealize Operations administrator to create a one-time passphrase that can be used instead of the administrator credentials to add a node to the cluster. This option is useful when the administrator wants to delegate the task of adding a node to another user without exposing the administrator password. The passphrase is valid for 24 hours and can be used only once.The trainee administrator can use the passphrase to authenticate into the vRealize Operations Manager administration interface and then select the Expand an Existing Installation option to add a new node into the cluster1.References:1:Expand an Existing Installation to Add a Data Node

A list view displays information about specific objects in a tabular format. You can select the object type, the metrics or properties to display, and the sorting and filtering options for the table. A list view is useful for comparing data across multiple objects or for exporting data to a CSV file.References:

A metric configuration in vRealize Operations is a collection of metrics that you can apply to one or more widgets in a dashboard. A metric configuration allows you to customize the metrics that you want to display on the widgets, and also to define the color, label, unit, and aggregation type for each metric.You can create, edit, or delete metric configurations from the Metric Configuration page in the Administration menu1.A metric configuration is not the same as a metric group, which is a predefined set of metrics that you can select from the widget configuration panel2. A dashboard navigation is a feature that allows you to link one or more widgets or views in a dashboard to another dashboard, and pass the selected object as a filter to the destination dashboard.When a dashboard navigation is created, the destination widgets or views are filtered by the selected object from the source dashboard3. An alert can be created from the Alert list widget, which displays the alerts for the selected object or group of objects in a dashboard.You can create an alert by clicking the Add Alert icon on the widget toolbar, and then selecting the alert definition, the object, and the alert properties4. Dashboards can be added by installing management packs, which are extensions that provide additional monitoring and management capabilities for various solutions and platforms.However, dashboards can also be added by creating custom dashboards, importing dashboards from the VMware Marketplace, or cloning existing dashboards.References:1:Manage Metric Configurations2:Select Metrics for Widgets3:Create Dashboard Navigation4:Create an Alert from the Alert List Widget: [Create and Configure Dashboards]

To change the subscription options for a datacenter migration scenario, the administrator can use the Change Plan option in the Scenario Builder. This option allows the administrator to modify the plan type, duration, and discount for the selected cloud provider without running a new scenario. The Change Plan option also updates the cost and savings estimates based on the new subscription options. The other options are not relevant for changing the subscription options. Change Cloud Provider is used to switch to a different cloud provider for the scenario. Edit Configuration is used to modify the configuration settings, such as CPU, memory, and storage, for the scenario. Edit Discount is used to apply a custom discount percentage for the scenario.References:Change Plan,Scenario Builder,Create a Scenario for Data Center Migration

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 anobject 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 Metrics2:Metrics and Properties Details3:Supercharge Your vRealize Operations with Super Metrics

vRealize Operations Cloud is the SaaS offering of vRealize Operations that provides the same features and capabilities as the on-premises version, but with the benefits of faster time to value, lower operational costs, and continuous innovation.vRealize Operations Cloud supports near real-time monitoring of your applications and infrastructure, with data collection intervals as low as 20 seconds1. Near real-time monitoring enables you to detect and troubleshoot performance issues, optimize resource utilization, and ensure SLA compliance more effectively.vRealize Operations Cloud also integrates with other VMware Cloud services, such as VMware Cloud on AWS, VMware Cloud on Dell EMC, and VMware Tanzu Mission Control, to provide unified visibility and management across your hybrid and multi-cloud environments2.

The on-premises editions of vRealize Operations (Standard, Advanced, and Enterprise) do not support near real-time monitoring, as the minimum data collection interval is 5 minutes3. Therefore, they are not suitable for scenarios that require faster and more granular data analysis and alerting.The on-premises editions also have different feature sets and licensing models compared to vRealize Operations Cloud4.References:

The Object List widget (A) is used to select objects. Once an object is selected, the Object Relationship widget (D, E) shows the relationship map of this selected object. To fulfill the requirement that the Alert List widget (F, G, H) should only show the active alerts for the selected object, the selection output of the Object List widget must be connected to both the Object Relationship and Alert List widgets.

Thus, you need to connect the output of the Object List widget (point B) to the input of the Object Relationship widget (point E), and also to the input of the Alert List widget (point G). This setup ensures that selecting an object in the Object List widget will update both the Object Relationship map and the Alert List with the relevant information for the selected object.
