Server labels a simple tool that allow you to add labels to a server as identifiers. They can be added when viewing a server and by clicking the 'Add Label' button. Once you have added a label you can easily remove it from your server.
Use cases
We use labels internally at Vizalo to identify servers that may run multiple applications for example, one of our internal servers is used for testing and prototyping and is known as "Moe" from The Simpsons. But it's name doesn't really describe what is running on it. So we add labels to describe what is running on Moe, for example at the time of writing we're testing out OpenObserve on Moe so we've added the "OpenObserve" label.
