What distinguishes a custom metric from built-in metrics?

A custom metric is distinct because it offers a user-provided metric identifier, allowing users to define and track specific performance indicators that are tailored to their unique needs. This customization enables organizations to measure aspects of their applications or infrastructure that might not be covered by built-in metrics, which are predefined and standardized.

Custom metrics give users the flexibility to monitor precise metrics that align with their business objectives or technical requirements, enhancing their ability to derive insights and take actionable steps based on the performance data collected. This user-centric approach is key to fine-tuning application performance and ensuring that critical metrics are easily accessible and relevant to specific use cases.

Built-in metrics are typically generalized and cover common performance aspects across various applications, whereas custom metrics are specifically tailored by the user, making them particularly valuable for specialized monitoring tasks.
