 According to the vRealize Operations User Guide1, one of the best ways to quickly identify the underlying problem of slow application VMs is to use the out-of-the-box Performance dashboards that display contention on both VMs and ESXi hosts. These dashboards show the key performance indicators (KPIs) of CPU, memory, disk, and network for the selected objects, and highlight any contention or saturation issues that may affect the performance. The administrator can use these dashboards to drill down into the details of the metrics, alerts, events, and properties of the objects, and isolate the root cause of the problem. The other options are not correct because:

• Under Inventory, selecting Manage Agent, then selecting the VMs, and running Remote Checks on ICMP, HTTP checks is not a helpful action, as it only verifies the connectivity and availability of the VMs, but does not provide any information about the performance or contention of the VMs or the ESXi hosts2.
• Under Report, using Configuration Report - Virtual Machines to list down possible changes that have occurred is not a helpful action, as it only shows the configuration details of the VMs, such as name, UUID, power state, guest OS, CPU, memory, disk, and network, but does not show any performance or contention metrics or alerts of the VMs or the ESXi hosts3.
• Under Administration, choosing Configuration, selecting Object Relationships, and then identifying the VMs and ESXi hosts relationship to generate a correlation of the metric, and finally, isolate the issue is not a helpful action, as it only shows the hierarchical and logical relationships between the objects, such as parent, child, sibling, and peer, but does not show any performance or contention metrics or alerts of the objects4. References: 1: vRealize Operations User Guide, pages 57-59, 62-632: vRealize Operations User Guide, pages 69-703: vRealize Operations User Guide, pages 81-824: vRealize Operations User Guide, pages 84-85.

According to the VMware vRealize Operations Reference Materials, the component that will be available when a user logs in to the vRealize Operations Product UI is the Dashboards page. The Dashboards page is the main interface of the Product UI, where the user can view and interact with various dashboards that display the data and analysis of the monitored objects and environments. The Dashboards page also allows the user to create and customize their own dashboards, as well as access other features such as alerts, reports, views, and policies. The other options are incorrect because they are not available in the Product UI, but in the Admin UI. The Software Update page, the Certificate management, and the System Status page are all components of the Admin UI, which is a separate interface that provides the administrative and configuration functions for the vRealize Operations cluster. The Admin UI can be accessed by logging in to the master node or the replica node of the cluster, using the admin user account or a user account with the Administrator role. The user who has access only to the Product UI cannot access the Admin UI or its components. References: vRealize Operations Manager Overview; Log in to vRealize Operations Manager; vRealize Operations Manager Administration

According to the VMware vRealize Operations Reference Materials, the Custom Script option in vRealize Operations is able to calculate measurements on a Guest OS. The Custom Script option allows the administrator to run a script on the Guest OS of a virtual machine and collect the output as a metric. The script can be written in any language that is supported by the Guest OS, such as PowerShell, Bash, or Python. The script can perform any calculation or operation that is required by the administrator, such as checking the CPU load, memory usage, disk space, or application status. The script output can be numeric or text, and it can be displayed in a dashboard, alert, or report. The other options, such as HTTP Check, UDP Check, or TCP Check, are not able to calculate measurements on a Guest OS. They are used to monitor the availability and response time of a web service, a UDP port, or a TCP port, respectively. They do not run any script on the Guest OS, nor do they collect any metric from the Guest OS. References: Custom Script; How to build a per-guest filesystem report in vRealize Operations using the ‘Breakdown By’ feature; How to Get In-Guest Metrics in vRealize Operations for Horizon 6

• A vRealize Operations support bundle is a collection of log and configuration files that help troubleshoot a vRealize Operations issue. You can create a support bundle from the vRealize Operations UI or from the command line interface (CLI) of the vRealize Operations nodes12.
• If the vRealize Operations UI is inaccessible, you cannot create a support bundle from the UI. Therefore, option C is not a valid process. You need to use the CLI method to create a support bundle from an on-premises deployment3 .
• To create a support bundle from the CLI, you need to log in to the vRealize Operations nodes using SSH and run the generateSupportBundle.py script. This script collects the log and configuration files from the nodes and creates a support bundle in ZIP format. You can then download the support bundle from the /storage/vcops/support directory of the nodes .
• However, you do not need to log in to each vRealize Operations node and run the script separately. You only need to log in to the Primary node and run the script once. The script will automatically collect the files from all the nodes in the cluster and create a single support bundle. Therefore, option A is not a necessary process. You only need to log in to the Primary node and run the script .
• Option B is not a correct process, as it does not use the generateSupportBundle.py script. The /var/log/messages file is not sufficient to gather the correct information for troubleshooting a vRealize Operations issue. You need to use the script to collect all the relevant log and configuration files from the nodes .
• Therefore, the process that will gather the correct information successfully is to log in to the vRealize Operations Primary node using SSH, and then run the generateSupportBundle.py script.This is option D.

According to the VMware vRealize Operations User Guide1, a Super Metric is a custom metric that is derived from one or more existing metrics. A Super Metric can be used to calculate complex formulas, aggregate data across multiple objects, or create new metrics that are not available by default. A Super Metric can be created using the Super Metric Editor in vRealize Operations.

However, before a Super Metric’s data collection may begin, the Super Metric must be enabled in a policy. A policy is a set of rules and settings that determine how vRealize Operations analyzes and manages the objects in the environment. A policy can be applied to one or more object types or groups. To enable a Super Metric in a policy, the administrator must edit the policy, select the Collect Metrics and Properties option, and then select the Super Metric from the list of available metrics. The administrator can also specify the collection level, collection interval, and retention period for the Super Metric.

The other options are not required before a Super Metric’s data collection may begin. Enabling in Alerts, Object Types, or Objects are not necessary steps for collecting Super Metric data. These options are used for different purposes, such as creating alert definitions, defining object relationships, or assigning policies to individual objects. References:
