Programmatically manage triggered alarms in vCenter with vRO

If you ever tried to manage vCenter’s alarms with vRO, you probably know how interesting this rabbit hole can be. Today, we’re going to see, how to acknowledge a specific alert in a vCenter with vRO and even try to make it as a pro, using some development best practices.

As often happens, a quick idea for a post tends to grow as I dive into it! 😊 In this case, we’ll use vRBT to write our code in TypeScript and introduce a new AlarmManagement class. Along the way, we’ll aim to follow some best practicesβ€”highly recommend Uncle Bob’s lectures for inspiration. This includes implementing a dedicated class for error handling, utilizing private methods, and more.

General goals:

  • Programmatically acknowledge a specific triggered on ESXi hosts.
  • Clear alarms of specific type.

The use case:

  • Certain configuration activities may trigger alarms during execution, which we aim to handle appropriately.
  • Specific alarms, such as those caused by periodic actions like backups, require special consideration.

The solution

Let’s take an example where we want to acknowledge a specific alarm and explore it in detail.
