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

 vRealize Operations provides two types of pricing cards, cost-based and rate-based, to calculate the price associated with your virtual infrastructure. You can assign pricing cards to vCenters or Clusters, depending on the pricing strategy determined by vRealize Operations administrator. The pricing cards help you to set the price for each resource present in your virtual environment. You can customize the pricing card as per your requirement.

• Cost-based pricing card: A cost-based pricing card calculates the price based on the cost of the resources defined in vRealize Operations. You can specify a multiplication factor for each resource type, such as CPU, memory, storage, etc., to adjust the price according to your business needs. The price equation using cost is:  x = Price
• Rate-based pricing card: A rate-based pricing card calculates the price based on the rate of the resources defined by you. You can specify a rate for each resource type, such as CPU, memory, storage, etc., in terms of units, such as MHz, GB, etc. You can also specify the charging period and the power state for each resource type.The price equation using rate is:  x = Price

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)
