The number of objects and metrics collected by VCF Operations in VMware Cloud Foundation (VCF) 9.0 plays a critical role in determining the size and scale of your VCF Fleet.

Using the VCF Operations UI, you can navigate to Administration->Control Panel->Cluster Management to view the cluster management-level stats but this only provides a subset of all the collected objects and metrics from the VCF Operations Adapters.

To get a more comprehensive understanding of all objects and metrics broken down by each adapter, you need to navigate to Administration->Cloud Proxies and iterate through each adapter as shown in the screenshot below.

It is not really scalable to use the VCF Operations UI to manually aggregate the total number of objects and metrics being collected, instead we can automate this by using the VCF Operations API!

After completing the VMware Cloud Foundation (VCF) Workload Domain Import workflow, I realized it would be helpful to be able to view the pre-check validations outside of the VCF Operations UI, especially if there are multiple pre-checks that have failed.

While the VCF Operations UI provides a good overview of all pre-checks, it does not provide any filtering or sorting, so you have to skim scroll through the entire list (55 in my case) to see which ones failed. For each failed validation, you can get more details including the recommended remediation, but you need to expand each section which can be painstaking if you have more than a few failures.

This is where we can leverage the power of automation and the VCF APIs ...

A useful feature in VCF Operations 9.0 is the ability to create a new VMware Cloud Foundation (VCF) Workload Domain from an existing vSphere environment, providing seamless onboarding into a VCF Fleet and getting access to the new VCF Fleet Management capabilities.

To access the VCF Import feature, navigate to the inventory view of your VCF Instance within VCF Operations and select Add Workload Domain->Import a vCenter Server to begin the workflow. A variety of deployment configurations are supported with VCF Import, you can refer to the official documentation for the complete list of requirement and minimum versions.

Deploying VCF 9.0 in a lab environment is an easy way to get hands on experience with this workflow. I recently installed ESX 9.0.1 onto a single ASUS NUC 15 Pro with a self managing vCenter Server for trying out the import scenario but I ran into the following pre-check error: Please ensure there is at least one cluster has more than 1 host

I guess I need to have more than one ESX host before I can proceed ... or do I? 🤔
