Final Answer:
True. A metric definition may only be referenced by one dashboard resource record.
Step-by-step explanation:
In the context of dashboard design and resource management, a metric definition typically represents a specific measurement or data source. To ensure clarity and consistency in dashboard creation, a well-designed system often restricts the referencing of a metric definition to a single dashboard resource record. This limitation simplifies the management of metrics, avoiding potential conflicts and ensuring that each metric is associated with a unique resource record.
By adhering to the principle that a metric definition is referenced exclusively by one dashboard resource record, the system maintains integrity and prevents unintended consequences. It allows for efficient tracking and updating of metrics within the dashboard infrastructure. This practice is particularly valuable in scenarios where metrics are dynamically generated or updated, ensuring that each instance of a metric is appropriately linked to its corresponding resource record.
In summary, the statement "A metric definition may only be referenced by one dashboard resource record" holds true, and it reflects a best practice in dashboard development. This approach promotes organization, clarity, and effective management of metrics within the system, contributing to a streamlined and maintainable dashboard design process.
