Which item is not typically monitored by custom devices?

Custom devices in monitoring frameworks are typically used to monitor infrastructure and services that may not be covered by standard monitoring configurations or capabilities offered by the monitoring tool.

Application servers, as a core component of application delivery, often fall under the standard monitoring scope, and their performance is usually assessed using built-in monitoring capabilities of tools like Dynatrace. These tools provide comprehensive visibility into application behavior, including metrics such as response times, throughput, and error rates.

In contrast, cloud databases, network appliances, and proxy servers can present unique monitoring challenges due to their varying configurations and usage patterns. Custom devices are often necessary to capture specific metrics and logs from these components, tailoring the monitoring approach to the unique needs of the environment.

Thus, application servers are more commonly monitored with standard configurations, while cloud databases, network appliances, and proxy servers require custom devices to ensure effective monitoring of their performance and health in non-standard setups.
