Quick Tip - Enabling vCenter Events for NTP (Network Time Protocol) or PTP (Precision Time Protocol) operations

by // 2 Comments

Starting with vSphere 7.0 Update 2, you may have noticed a new "Enable monitoring events" setting when configuring time for your ESXi hosts, whether that is using the classic Network Time Protocol (NTP) or the newly introduced Precision Time Protocol (PTP).

What exactly does this enabling this setting do? This was a recent question that I had answered internally and figured I would share the detail as the description may not be super clear. Simply put, this enables the publishing of different NTP and/or PTP operations as vCenter Server Events, which can then be used to audit time skews in your environment for compliance to troubleshooting or debugging.

vSphere Event-Driven Automation using VMware Event Router on VMware Cloud on AWS with Knative or AWS EventBridge

by // Leave a Comment

The VMware Event Broker Application (VEBA) is a popular VMware Event-Driven Automation solution that can be consumed using either the open source or commercial offering from VMware. The commercial offering of VEBA is already available to customers today via our Tanzu Application Platform (TAP) offering, which I have previously written about here. The open source offering of VEBA can be consumed in either a pre-packaged Virtual Appliance or a native Kubernetes Application called for those with an existing Kubernetes cluster.

Deploying the VEBA Virtual Appliance is well documented (here and here) and I wanted to spend some time covering the native Kubernetes deployment model, as it there are actually a couple of options and most recently, this came up in a customer discussions as they were interested in forwarding vSphere Events from VEBA to AWS EventBridge.

In the open source version of VEBA, there is a component called the VMware Event Router, which is responsible for connecting to an event source such as vCenter Server and then forwarding those events to a processor which can either be a a function that you have written to react to a specific event using Knative or to AWS EventBridge to integrate with other AWS native services like CloudWatch as an example.

To demonstrate the two different ways to deploy the VMware Event Router, I have created the following Github repo https://github.com/lamw/vsphere-event-driven-automation-vmware-event-router that provides an example to easily deploy the VMware Event Router to an existing Kubernetes cluster. For my environment, I will be using VMware Cloud on AWS and the managed Kubernetes offering called Tanzu services, which is included as part of the base offering and there is no additional cost of running the Kubernetes infrastructure, which is certainly an added bonus 😀

vSphere Event-Driven Automation using Tanzu Application Platform (TAP) on Tanzu Community Edition

by // 2 Comments

Right before the holiday, I had spent some time exploring Tanzu Application Platform (TAP), which also recently GA'ed. TAP provides developers with an application-aware platform that focuses on making the developer experience easy for developing, building and running applications on Kubernetes.


If you are interested in a quick technical deep dive into TAP, check out this video by Scott Sisil, introducing TAP:

One of the core components of TAP is the Cloud Native Runtime (CNR), which is VMware's commercial offering of the popular open source project Knative. The VMware Event Broker Appliance (VEBA) project also makes use of Knative as our backend to provide customers with an event-driven automation solution.

Early on in the VEBA project, we knew that we wanted to develop and innovate with the community in the open but we also understood there would be users who would want an officially supported offering that they can call or file support requests when needed. Early last year, Michael Gasch, the lead architect for VEBA started to port the code from the VMware Event Router, which is the heart of VEBA into CNR's Tanzu Sources for vSphere and start unifying the two code bases. The goal is to ensure that users of the open source project VEBA will also have a consistent user experience in terms of function deployment when using the commercial offering.

As shared back in Dec, I was able to successfully deploy TAP, CNR and Sources for vSphere all running in Tanzu Community Edition (TCE), which is a completely free Enterprise-grade Kubernetes available to anyone in the community to use. For those interested, you can find the instructions below on how to deploy and configure TAP to enable vSphere event-driven automation capabilities for your infrastructure. If you are interested in deploying this using the Tanzu Kubernetes Grid (TKG) Service, check out this other recent blog post that outlines the specific steps.
