 To access the Troubleshoot with Logs dashboard from vRealize Operations, the administrator must configure the vRealize Log Insight integration from the vRealize Operations interface and configure vRealize Operations in vRealize Log Insight. The Troubleshoot with Logs dashboard allows the administrator to view graphs of log events in the environment, or create custom sets of widgets to access the information that matters most. The dashboard requires the integration of vRealize Operations with vRealize Log Insight, which is a log management and analysis tool1. The integration can be done in twoways: by configuring the vRealize Log Insight adapter in vRealize Operations, or by configuring vRealize Operations in vRealize Log Insight. Both methods are necessary to access the Troubleshoot with Logs dashboard and the Logs tab in vRealize Operations2. References: 1: Troubleshoot with Logs Dashboard 2: Configuring vRealize Log Insight with vRealize Operations

 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.

Data nodes are the type of node in a vRealize Operations (vROps) design that allow an administrator to scale out vROps to monitor very large environments. Data nodes are additional nodes that have all the vROps services installed, such as UI, Controller, Analytics, Collector, and Persistence. Data nodes perform data collection and analysis, and increase the capacity and performance of the vROps cluster. Data nodes can be added or removed as needed to adjust to the changing workload and environment size. Remote collectors are not a type of node in a vROps design, but a separate component that can be deployed to collect data from remote sources and send it to the vROps cluster. Remote collectors do not store data or perform analysis, and do not increase the capacity or performance of the vROps cluster. Replica Primary nodes and Primary nodes are not the type of node that allow an administrator to scale out vROps to monitor very large environments, but the type of node that provide high availability and continuous availability for the vROps cluster. Replica Primary nodes and Primary nodes contain critical services that cannot be replicated across all cluster nodes, such as Global xDB, NTP server, and GemFire locator. Replica Primary nodes and Primary nodes do not perform data collection and analysis, and do not increase the capacity or performance of the vROps cluster. References: About vRealize Operations Cluster Nodes, section “About vRealize Operations Cluster Nodes”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.
