Listing all VMware Horizon Events

by // Leave a Comment

One very useful feature in the latest VMware Horizon (2106) release is the introduction of a new Audit Events API, that will finally allow users to retrieve all Horizon events in a programmatic manner. Previously, the only method of extracting the Horizon events was to unfortunately query the SQL Server database directly.

Since VMware Horizon is not a solution I normally work with, I was actually curious on how many events are produced by Horizon? Back in 2019, I shared how to retrieve and list all vCenter Server Events and ended up publishing a Github repo that folks can quickly view and search for a specific event, which is especially useful if you are using the VMware Event Broker Appliance (VEBA) solution.

After speaking with Chris Halstead, one of the most knowledgable person on VMware Horizon that I know, a list of all known Horizon events has never been published.

Quick Tip - Preserving FQDN hostname on Photon OS

by // 1 Comment

Over the weekend, I was troubleshooting an issue that was reported by one of our VMware Event Broker Appliance (VEBA) users who was helping with testing one of our upcoming features. The user found that after rebooting the VEBA appliance, the Antrea interfaces were no longer being re-created and pod networking seems to have been broken.

We initially thought it was related to switching to the latest Photon OS version or updating to the latest Antrea CNI release, since everything else was pretty much the same. Even after reverting both versions back to what we initially had, the reboot issue continued to persist. What was even more strange was that the current shipping version of the VEBA (v0.6.1) OVA was not experiencing this issue and had no problems with an OS reboot, which is something I have done many times.

The only logical conclusion that I could come up with to explain this problem is that a behavior change must have occurred within Photon OS from the time we built the previous appliance to what we are seeing now. While troubleshooting Antrea, it was pointed out that Kubernetes (K8s) node is probably unhealth and if so, I may want to look at the kubelet logs to see if it provided any hints. I initially did not both looking at the K8s layer, thinking this was related to change in Antrea since it handled pod networking. Looking at the kubelet logs, I found a ton of entries with the following:

396 kubelet.go:2243] node "veba" not found

I thought this was a bit strange, especially as our appliance has its hostname configurred with a Fully Qualified Domain Name (FQDN) which is veba.primp-industries.local and we had proper entries in both /etc/hostname and /etc/hosts.

Sure enough, when I ran hostname, they all returned the short hostname instead of the FQDN (which it returned properly prior to the reboot)

ESXi on Intel NUC 11 Extreme (Beast Canyon)

by // 17 Comments


The NUC 11 Extreme (codenamed Beast Canyon) is the latest in Intel's Tiger Lake based NUC lineup which includes the NUC 11 Performance (Panther Canyon), NUC 11 Enthusiast (Phantom Canyon) and NUC 11 Pro (Tiger Canyon). As you can see from the picture above, the codename for the NUC 11 Extreme is quite fitting as this is currently the largest "NUC" that Intel has built to date, coming in at 8L. Yes, this is definitely "stretching" the NUC label in terms of what folks historically expect but I believe Intel is simply expanding on their well known NUC brand, especially as there are also NUC laptops.

However, this is also not the first time Intel has explored a larger NUC design. In 2020, Intel introduced the NUC 9 Pro (Quartz Canyon) and Extreme (Ghost Canyon) which took advantage of the new NUC Compute Element and enabled a new modular design and form factor adding support for discrete GPU and PCIe expandability. As a successor to the NUC 9, the NUC 11 Extreme extends this concept further by adding support for a full length discrete GPU, which is the primary driver for the larger form factor.

The NUC 11 Extreme can also enhance your homelab experience with LED lights which are located underneath the chassis and on the front with the classic Intel NUC Skull. Even cooler, the design in the front is customizable and can be user replaced with a different graphic. For an example of what this could look like, jump down to the customizable logo section of this blog post 🙂

I know there are a number of folks in the VMware community who are currently using the NUC 9 for their VMware Homelab, especially for those with GPU and/or additional network and storage requirements. Let's now take a closer look at what the NUC 11 Extreme has to offer the VMware Community.
