Automating the new VMware Cloud Notification Gateway (NGW) User Notification Preferences

by // 2 Comments

Last week the VMware Cloud team released one of the highly requested feature which is the ability to control notification preferences for an individual user, which is provided as part of the VMware Cloud Notification Gateway (NGW) service. Users can now login to the VMware Cloud Console (VMC UI) and on left hand side, you should now see a new Notification Preferences tab which will allow you to specify which notifications you wish to receive via the Email channel.


As of writing this blog post, there is currently over 200+ notifications that can be configured which are broken up across the following four categories:

  • Elastic DRS (7)
  • Organization General (128)
  • SDDC Maintenance (61)
  • VMware Site Recovery Service (23)

Today, the notification preferences is configured on a per-use basis and by default, users are automatically subscribed to all notifications. The ability to customize is great but with over 200+ notifications to select or de-select from, this could be a difficult task, especially with a large number of users who may or may not understand each and ever single notification type. This is certainly an area the VMware Cloud team will be looking to enhance in the future to make it even easier to consume and customize.

In the mean time, to help with making this customization change easier within your organization, we can also take advantage of the new NGW Notification Preferences API. What better way to demonstrate this than incorporating this into my VMware Cloud Notification Gateway Community PowerShell Module, which is also available for consumption within the PowerShell Gallery.

How to programmatically retrieve vCenter Server Patch & Update History?

by // 3 Comments

After upgrading my homelab to the latest vSphere 7.0 Update 3 release, I was just looking at the "History" tab within the Virtual Machine Management Interface (VAMI), which gives you a historical view of all the patches and updates that have been applied to your vCenter Server since its initial deployment. I am not exactly sure when this was feature was introduced, but it can definitely be useful for both auditing but also debugging/troubleshooting purposes.

Of course, I was curious about this information and wanted to see if I could retrieve it using something like PowerCLI. However when I started to look for the API, I realized that there may not be a public API for this ... but that did not stopped me and taking a look at Chrome Developer, I quickly saw the endpoint which was /rest/appliance/update/history and I was able to figure out a workaround giving the same data.

Below are two examples on accessing this data using either PowerShell or cURL

Quick Tip - Retrieving vSphere Distributed Switch (VDS) DVPort ID & Stats using PowerCLI

by // Leave a Comment

I have seen several variations of this question get asked internally on how how to retrieve the DVPort ID and/or Stats on a vSphere Distributed Switch (VDS). Usually the question is prefaced with an example output from an ESXi host like the one show below using a classic CLI called esxcfg-vswitch. As you can see, there are a number of DVPort IDs which are either mapped to a physical NIC on the ESXi host or to a specific VM and its network adapter, if there is more than one.


My usual response for these sort of questions is that yes, it can be programmatically and automatically retrieved without going directly to an ESXi host. The answer is by using the vSphere API and specifically the set of methods provided by the VirtualDistributedSwitch managed object, which will allow users to retrieve all things related to the VDS.

Note: Although PowerCLI does provide some higher level cmdlets for managing VDS and Distributed Virtual Portgroups (DVPG), not everything that is available in VDS API is available through these higher level cmdlets, but that does not mean you can not use PowerCLI to easily retrieve all this additional information.
