Using the VCF Diagnostic Tool for SDDC Manager

Products

• VMware Cloud Foundation

Issue/Introduction

The VCF Diagnostic Tool (VDT) is a diagnostic tool that is run directly on the SDDC Manager. It runs through a series of checks on the system configuration and reports user-friendly PASS/WARN/FAIL results for known configuration issues. It also provides information (INFO) messages from certain areas which we hope will make detecting inconsistencies easier. The goal of these tests is to provide live diagnostic information to the user about their environment which might otherwise be missed.  

The utility is completely read-only for the entire environment. 

The utility logs to the following directory on the SDDC-Manager.

/var/log/vmware/vcf/vdt/

3.SSH into the SDDC-Manager and elevate to root with su.

4.Change your directory to the location of the file, and unpackage the vdt zip file:

• cd /home/vcf/

5.Run the tool with the command:
