[TP] Lab - Creating and Using Entity Selectors

In this lab, we will learn how to create entity selectors, test them via the API, and then use them to precisely define the perimeter of a management zone.

What you will learn in this TP :

Validate access to the Dynatrace cluster

Generate an API Token with the correct rights

Understand the importance of dynamic selectors

Banish technical ID rigidity

Prerequisites

What you will learn in this section :
Validate access to the Dynatrace cluster
Generate an API Token with the correct rights

You must have a Dynatrace cluster (SaaS or Managed) with agents deployed, as well as an API Access Token with read entity rights (`entities.read`).

Golden Rule of Design (Scaling)

What you will learn in this section :
Understand the importance of dynamic selectors
Banish technical ID rigidity

To guarantee optimal performance and simplified maintenance, a strict architectural rule must be respected in your configurations.

The Golden Rule
For each selection rule, you must imperatively define either an Entity ID (unique technical identifier) or an Entity type.

Good practice: The use of fixed Entity IDs is prohibited in production because it's too specific and doesn't survive resource redeployment.

Difficulty level: (3/5)
