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)

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

A support bundle is a collection of log and configuration files that can help troubleshoot a vROps issue. To create a support bundle, the system administrator can use the vROps UI and select the option to create a light or full support bundle. A light support bundle includes 24 hours of logs, while a full support bundle includes all available logs and configuration files. For an intermittent issue that occurred in the last 12 hours, a light support bundle should be sufficient to collect the relevant information. The system administrator can also select the cluster nodes that need to be evaluated for support, and download the support bundle in ZIP format for analysis or sending to VMware Technical Support1. The other options are not recommended or efficient ways to collect the relevant information. Collecting the vCenter and vROps primary node logs using SSH and the vm-support utility would not include the logs from the other vROps nodes, and would require manual steps to gather and compress the files. Using the vROps UI to create a full support bundle for ESXi, vCenter, and primary vROps nodes would include unnecessary and excessive data that could slow down the process and consume more disk space. Using SSH to copy the log files from each of the vROps nodes from /var/log/warn & /var/log/messages locations would also require manual steps to gather and compress the files, and would not include the configuration files that could be useful for troubleshooting. References: 1: Create a vRealize Operations Support Bundle
