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 2: Service and Application Discovery - VMware 3: Configure Service and Application Discovery - VMware : Create Application Definition - VMware Docs : Configure White List - VMware Docs

To enable High Availability (HA) on a vRealize Operations cluster, the following two options are requirements:

• The cluster must have at least one Primary node: The primary node is the first node that is deployed in the cluster and it is responsible for managing the cluster configuration, user interface, and administration functions. The primary node also stores data and performs analytics like any other data node. Without a primary node, the cluster cannot function properly1.
• The cluster must have at least one Data node: A data node is a node that collects data from various sources, stores data in its local file system, and performs analytics and alerting functions. A data node also participates in the cluster load balancing and data replication. To activate HA, you must have at least one data node deployed, in addition to the primary node. This allows the creation of a replica node that can take over the primary node functions in case of a failure2. References: 1: About vRealize Operations High Availability 2: High Availability (HA)

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 Configurations 2: Select Metrics for Widgets 3: Create Dashboard Navigation 4: Create an Alert from the Alert List Widget : [Create and Configure Dashboards]
