Quick Tip - Retrieving vSAN Congestion Health Programmatically

by // 1 Comment

While catching up on post-Explore email, I received a question from a customer who has a large number of vSAN deployments spanning their ROBO environment. In one of their environment, they had some physical congestion issue that caused some problems for their vSAN stretched cluster and they were looking for a way to monitor the vSAN congestion health, which is available as part of vSAN Health.


Since this information is available as part of vSAN Health, we can certainly leverage the vSAN Health API to retrieve this information programmatically but we can also look at using the PowerCLI Test-VsanClusterHealth cmdlet to get this information in a quicker manner for administrators.

Quick Tip - vCenter Server Advanced Settings Reference

by // 1 Comment

Simliar to my ESXi Advanced and Kernel Settings reference, I was recently asked about creating one for vCenter Server to capture all the default out of the box advanced settings.

With some automation in place, I deployed all major releases of the vCenter Server Appliance (VCSA) from 6.7 to 8.0 which is available in this repo: https://github.com/lamw/vc-advanced-settings

New PCI Compliance Audit APIs for VMware Cloud Foundation (VCF) 5.2

by // Leave a Comment

One very interesting capability that I had noticed while reading the the latest VMware Cloud Foundation (VCF) 5.2 release notes are new VCF APIs for auditing PCI Compliance.

VCF users can now use a new set of APIs that audit VCF configuration for compliance with 9 relevant PCI-DSS controls

In addition to exploring these new VCF APIs, I thought this would also be a good opportunity to contribute to the popular PowerShell Module for VMware Cloud Foundation which is also the basis for several other useful VCF modules for automation:

To demonstrate the new VCF Compliance Audit APIs, I crated the following new functions which I have also submitted a pull request (PR) 291 to incorporate functions in a future release of the PowerShell Module for VMware Cloud Foundation, which I hope will get merged by the time this blog post is live!
