Where to start with a VVF fault: the VCF Installer, VCF Operations features, or a component's own tools.
From Ultra Transcenders 2V0-18.25 by Tony Rough (coming November 2026)
VCF Operations is the first stop for most running-platform faults once it is collecting data, while the installer, vCenter and the ESX host each keep their own lower-level tools. Start at the top of this table for broad questions and work down as the fault narrows. Figure 1.2 groups the same faults by where they arise.
| Fault or question | Tool | What it gives you | Detail in |
|---|---|---|---|
| Deployment or validation fails | VCF Installer: Tasks panel, validation page, domainmanager.log |
Failed tasks, remediation text, the service log | Deploying VVF with the VCF Installer |
| On a VCF licence only: is the stack healthy, and are NTP, DNS or certificates at fault? | VCF Health in VCF Operations | Continuous monitoring: expired certificates, NTP drift, DNS misconfiguration, configuration errors. It requires a VCF licence and a system deployed by the VCF Installer, so a VVF licence does not give it | VCF Operations: configuration, log bundles and Log Assist |
| Does this match a known product issue? | Diagnostic Findings | Known issues, security exposures and best-practice recommendations, with remediation | VCF Operations: configuration, log bundles and Log Assist |
| Why did this alert fire, and what else changed? | Troubleshooting Workbench | Events, property changes and anomalous metrics in a chosen scope and time range | Troubleshooting VVF with VCF Operations |
| What do the logs say across hosts and vCenter? | Analyze Logs, with VCF Operations for logs | Queries and filters over infrastructure logs; log-based alerts and dashboards | VCF Operations for logs |
| vSAN cluster health | vSAN Skyline Health | Findings on hardware compatibility, network, configuration, devices and objects, with a health score | vSAN |
| vCenter appliance itself | vCenter Management Interface on port 5480; service-control |
Appliance administration and service control | vCenter |
| Single host problem | VMware Host Client, DCUI, ESX Shell | Direct access when vCenter cannot help | ESX hosts |
| Workflow failure in orchestrator | Token replay, validation, script and schema debugging, metrics | Run-level evidence inside the workflow | VCF Operations orchestrator: configuration and workflows |
| Broadcom needs logs on a case | Log Assist | Generates a bundle and uploads it from VCF Operations | VCF Operations: configuration, log bundles and Log Assist |
Common trap: A workbench session will still be there tomorrow with its changes - active sessions do not persist after logging out. Changes to scope, time or evidence are not saved, and the session returns only as a recent search.
This note is one section of Ultra Transcenders 2V0-18.25: VMware vSphere Foundation 9.0 Support, an independent study guide that explains every topic the exam covers by technology, with comparison tables, diagrams and the common traps, plus a glossary linked to Broadcom TechDocs.

Where to find logs for ESX, vCenter, the VCF Installer and the VCF Operations products.
How the starting state of an existing vSphere environment decides the path to VVF 9.0.
What evaluation mode allows, what happens when a licence expires, and how recovery works.
What Connected, Not Responding and Disconnected mean, and what each means for running VMs.
What each vSphere HA agent state says about a host, and what it means for failover.
Which objects stay available after each single failure in a vSAN stretched cluster.
How to tell All Paths Down from Permanent Device Loss on ESX, and what each does to VMs.
