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 practices—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:

  • 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.
