VMware vCenter Health checks in 6.7U1

I do have the feeling that, while promoting the fully supported HTML5 client in vSphere 6.7u1, more and more customers are curious about the features and benefits in this release.

In this blog post I want to share a few informations about an added feature which I think is underrated and most people do not know about.

As published in the “What’s new in vCenter Server 6.7 Update 1” post you now have the option to view your vCenter’s health status! Like the already added vSAN Health feature, VMware added the vCenter health view into the HTML5 framework in the 6.7 Update 1 release.

You can find the health status at “vCenter HTML5 -> Monitor -> Health”

To use it’s fully potential the Customer experience improvement program (CEIP) must be enabled. If not enabled during the installation/upgrade of vCenter 6.7 Update 1, you can do so at the “vCenter Administraton” panel:

By enabling it, the health status feature will also provide solutions and KB article to solve certain warnings and situations and helps to prevent problems first hand before failure happens. As stated in the “What’s new in vCenter Server 6.7 Update 1” this is a new feature and should be viewed as such:

Keep in mind this is a new service and will not have all health checks day one. The good news is this services independent of the vSphere release cycle. It features an out-of-band delivery infrastructure. If you are running vSphere 6.7 you also have the same capabilities as well. The goal here is overtime this service will become more proactive to ensure you have a healthy vSphere environment.

Let’s view some warnings at the vCenter health check and what this feature offers to solve these warnings.

By selecting one of the checks it will split the view and reveal more information about the status itself. In this example the check “Disk space check for VMware vCenter Server Appliance” is selected and shows two optional views “Details” and “Info”.

If the check for disk space on the vCenter server appliance is showing a warning and you need to increase the disks you’ll find the referring VMware knowledgebase article in the upper right corner at “Ask VMware”!

Same at warning / error level. You can view the status of the related objects, view the information about this health check and how to solve the situation.

You can simply retest your environment by selecting the “RETEST” button on the upper right corner if you’ve made changes to the configuration.

I really like this feature and hope to see more health checks added in the future. The vSAN health checks are already extensive and an awesome option to show the customer if something is wrong in an instant. You can take a detailed look at the vSAN health checks at the VMware Docs “About the vSAN Health Service“.
