vSphere Diagnostic Tool is a python script that runs diagnostic commands on the vCenter Server Photon Appliance to return useful troubleshooting data while running within the confines of the local environment with out upstream dependencies.
The motivation behind this tools is to provide multiple Pass/Fail tests to quickly facilitate the rapid isolation of issues encountered in the vSphere environment.
This tool has already been tested by a select group within Support to assist us in looking for bugs as well as provide feedback to the vSphere product team.
The tool itself is currently a set of self contained python and bash scripts that can perform the following tests for vCenter Server Appliance 6.5 or newer:
- vCenter Basic Info
- Lookup Service Check
- AD Check
- vCenter Certificate Check
- Core File Check
- Disk Check
- vCenter DNS Check
- vCenter NTP Check
- vCenter Port Check
- Root Account Check
- vCenter Services Check
- VCHA Check
We use a simple Pass/Warning/Fail status for each test as well as include KBs or other knowledge sources for Warning and Fail results which provides next steps to solving the issue.
Each test should be self-explanatory in its meaning, findings, and directions. If any check isn’t clear in its direction, please report the issue to our team at firstname.lastname@example.org and we will address it.
This tool is considered to be in the Alpha phase so it is possible that false positives could be present, though we haven't encountered any to date. Please provide any and all feedback.
The team are continuing to add new capabilities and checks into this tool as we have a backlog of over 100 new features that we are developing. We have a long term goal to have this tool made available in all current and future VMware products with PhotonOS appliances as well as ESXi.
1) Download the ZIP file from the link on the top of this page.
2) Upload the ZIP file to the vCenter system to be analyzed.
3) Use the file-moving utility of your choice (WinSCP for example) to copy the entire ZIP directory to the /root directory.
NOTE: If you have troubles connecting to a vCenter appliance using WinSCP, please see Error when uploading files to vCenter Server Appliance using WinSCP
4) Change directory to the location of the file, and unpackage the zip:
$ cd /root/
$ unzip vdt-version_number.zip
5) To run the tool, first make sure you have unzipped the ZIP file, and have changed to the newly created directory for Pulse/VDT. Then, run the following command:
$ python vdt.py
The tool will prompt for the password for email@example.com. Many checks will run even if credentials are not supplied.
Review the output by scrolling up and down in the window. Each test should be self-explanatory in it's meaning, findings, and directions. If any check isn't clear in its directions, report the issue to firstname.lastname@example.org and our team will address it.

vSphere Mobile Client enables administrators to monitor and manage vSphere.
Virtual Machine Desired State Configuration (VMDSC) allows virtual administrators to specify VM CPU/Memory desired state which will take effect upon the next Guest OS reboot. This removes the burden of having to schedule a downtime window with the business/app owners.
Cross vCenter VM Mobility - CLI is a command line interface (CLI) tool that can be used to migrate or clone a VM from one host to another host managed by a linked or isolated vCenter (VC) instance.
