Which of the following best describes metadata in Dynatrace?

Metadata in Dynatrace refers to key/value pairs that provide additional descriptive information about various entities within the platform. This additional layer of detail enhances understanding and context around the entities being monitored, such as applications, services, hosts, or cloud infrastructure components.

By using key/value pairs, Dynatrace allows users to define and capture attributes that are relevant to specific monitoring scenarios. For example, a user might define metadata to capture the environment (production, staging, development), the owner of an application, or the version of a service. This structured information aids in better organizing, filtering, and analyzing performance data within the Dynatrace interface.

While other options touch on aspects of Dynatrace features, they do not encapsulate the essence of metadata as key/value pairs that enhance the understanding of entities. Identifiers, tags, and notifications each serve different purposes that do not align with the comprehensive role of metadata in providing extended context and attributes to monitored components.
