 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:

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”.

 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
