 The frequency at which new services are discovered when using Service Discovery in vRealize Operations is every 5 minutes. Service Discovery is a feature of vRealize Operations that allows the administrator to discover and monitor the applications and services running on the virtual machines in the environment1. Service Discovery can be performed using two methods: credential-less and credential-based. Credential-less Service Discovery uses VMware Tools to query the guest operating system for the list of running processes, and then matches them with a predefined set of signatures to identify the applications andservices2. Credential-based Service Discovery uses the credentials provided by the administrator to log in to the guest operating system and run commands or scripts to discover the applications and services3. Credential-less Service Discovery collects the information about the services running inside the guest every five minutes4. Credential-based Service Discovery collects the information about the services running inside the guest every 24 hours5. Therefore, the frequency at which new services are discovered when using Service Discovery in vRealize Operations depends on the method used, but the most frequent one is every 5 minutes for credential-less Service Discovery. References:

Custom groups are collections of objects that you define based on criteria that you specify. You can use custom groups to assign different vRealize Operations policies to a particular set of objects that share common characteristics or belong to a specific business unit1. Custom groups allow you to override the default policy settings for the objects in the group and apply a different policy that suits your requirements2. For example, you can create a custom group of ESXi clusters that run database servers and assign a different capacity policy to them than the rest of the clusters in your environment2. References: = 1 Managing Custom Object Groups in vRealize Operations - VMware Docs, 2 Policies - VMware Docs

 The Troubleshooting Workbench is a feature in vRealize Operations that helps you perform advanced troubleshooting tasks on an alert or an object. You can look for potential evidences of a problem within a specific scope and time range. The potential evidences are based on three types of data: Alerts, Events, and Property Changes. Alerts show the active and inactive alerts that are related to the object or its peers. Events show the events that are based on a change in the metrics, such as spikes, drops, or anomalies. Property Changes show the changes in the configuration or properties of the object or its peers, such as CPU, memory, or disk allocation. These types of data help you identify the root cause of the issue and take corrective actions. Symptoms and Anomalous Metrics are not considered as potential evidence in the Troubleshooting Workbench, although they may be used to trigger alerts or events. Logs are not displayed in the Troubleshooting Workbench, but they can be accessed from the Logs tab of the object. References: Discovering Potential Evidences Using the Troubleshooting Workbench, Solving Real Problems with vRealize Operations TroubleshootingWorkbench, Troubleshooting Workbench Home Page, vROps 8.0 Troubleshooting Workbench and Blue Medora

 According to the vRealize Operations Sizing Guidelines, the supported node configurations during installation are Large, Very Large, and Medium. These are the default configurations that VMware offers based on the number of objects and metrics to be monitoredby vRealize Operations. Each configuration has a different amount of vCPU, memory, disk space, and network requirements. The administrator can choose the configuration that best suits the existing infrastructure and the expected growth of the environment1.

The other options are not supported node configurations during installation. Tiny and Small are not valid configurations for vRealize Operations 8.x and later versions. These configurations were available for vRealize Operations 6.x and 7.x versions, but they are not recommended for production environments due to their limited capacity and performance2. No limit is not a configuration option, but a statement that indicates that there is no upper limit on the number of nodes that can be added to a vRealize Operations cluster. However, the number of nodes depends on the node configuration, the network latency, and the data source type3.
