AWS Certified Developer Associate DVA-C02 Practice Question
To increase the transparency into the performance of a critical web application, a developer needs to record event-specific information that can indicate the system's health. Without altering the existing infrastructure setup, which method should the developer choose to directly integrate this telemetry capture within the application's code base?
Utilize a configuration management service to automate the creation of telemetry resources for the monitoring service.
Adapt the system agent pre-installed on the host machine to gather and dispatch the new set of metrics.
Incorporate the necessary API calls to the monitoring service to transmit the custom telemetry data as required.
Leverage the high-level functionalities of a software development kit to streamline the transmission process of telemetry data.
The correct method for a developer to directly insert custom telemetry from within the application is to use the monitoring service's API to publish these metrics. This technique is immediate, requires minimal additional setup, and enables straightforward integration into the code base. The other options, such as utilizing configuration management tools, system agents for metric collection, or SDKs that simplify API interactions, are valid in certain contexts but may be more indirect or less efficient for the task of custom metric emission directly from the application.
