Quick Tip - How to disable the vCenter Server Update Notification banner?

03.17.2021 by William Lam // 5 Comments

I received this question on Twitter from Andreas asking the following:

Is there a way to disable or postpone the #vCenter update notification logon message in the web client? @lamw @vmwarecares @VMwarevSphere pic.twitter.com/tYsikiesIP

When a new vCenter Server update is available, a notification banner is automatically displayed in the vSphere UI. This functionality was introduced as part of vSphere 7.0 and part of the new vSphere Lifecycle Manager (vLCM) capability. This is a very useful feature since administrators spend most of their time in the vSphere UI and when new update was available, it would only be displayed in the VAMI UI, which most folks were not logging into on a regular basis.


Today, the update notification banner is always displayed and there is no way to temporarily disable it. This can be annoying if you do not intend to update your vCenter Server immediately and I assume this is why Andreas was asking about either postponing or disabling the notification all together.

Currently, the only way I am aware of for disabling this notification is to actually disable the vCenter Server Life-Cycle Manager Remote Plugin itself. You can do this by navigating to Administration->Solutions->Client Plugins and then selecting "vCenter Server Life-cycle Manager" and click on the Disable button. You can refresh the webpage or logout and you should no longer see the notification banner.

Disclaimer: By disabling the vCLM plugin, you are disabling more than just the banner but all vCenter vLCM functionality including Interop and Update Planner capabilities. If these are things you require, do not disable the plugin.


I can certainly see a nice feature enhancement in the future where vLCM notifications can be postponed or deferred to a later date. I will share this blog post and feedback with the vLCM PM for consideration.

Adobe Flash is going away, is your VMware environment and IT Organization ready for it?

10.29.2020 by William Lam // 12 Comments

Hopefully this news should not come as a surprise to anyone but at the end of this year (December 31, 2020), Adobe and all mainstream web browsers will remove Flash functionality preventing users from interacting with any Flash-based web applications. This will also impact usage of VMware products that still uses Flash such as older versions of vSphere with the vSphere Flash Web Client or vCloud Director with their Flash-based Tenant UI as an example.


The large majority of VMware customers have already migrated off to newer versions of VMware products that no longer rely on Flash and this announcement will be a no-op for them. However, the reality is that not every customer has been able to meet this deadline for one reason or another will still have VMware products running in their Production environment that uses Flash even after the official end of life.

For these customers, it is really important to understand what are some of the implications and considerations to be aware of leading up to end of the year.

Creating vCenter Alarms based on Task Events such as Folder creation

02.11.2019 by William Lam // 12 Comments

The vCenter Server Events sub-system is an incredibly rich and powerful interface that enables customers to monitor, alert and even trigger additional actions based on a particular event. One such example that I have written about before is to key off of a VM provisioned event and automatically apply security hardening settings when the VM is created or cloned. This can be useful if customers are not taking advantage of VM Templates or if a VI Admins manually creates a VM from scratch, you can still ensure you have a compliant VM deployment through the use of Automation. You can either poll for the VM created event and then execute a script as shown in this example or you can automatically trigger a remote action by generating an SNMP trap when the event actually occurs.

The possibilities are truly endless on what you can do with vCenter Events and for the complete list of all Event types, you can refer to the vSphere API documentation here. One thing to be aware of is that not every operation within vCenter Server generates an Event, one example of this is when a Folder object is created or deleted. You can use vCenter Server Tasks sub-system to query for this info but there is not a respective vCenter Event that you can key off of to generate an Alarm for example. This was something I had noticed myself and assumed it was a limitation of the platform or feature teams that publish VC Events.

Recently, this question came up again from a customer who was looking for a way to trigger an alarm every time a VM Folder was created. I took another look at this and came to learn about a more generic type of Event that can be used to create an Alarm for such use cases where a native VC Event may not exists called a Task Event.
