Which method allows for more effective control over problem notifications in Dynatrace?

The option related to alerting profiles with filtering rules is the most effective method for controlling problem notifications in Dynatrace. This method allows users to create customized alerting profiles that specify the conditions under which notifications are generated, including the ability to filter based on specific criteria such as the entities involved, the severity of the issues, or even specific business conditions.

By employing filtering rules within alerting profiles, users can significantly reduce noise and focus on the most relevant notifications that matter to their team's operational objectives. This level of customization ensures that alerts are actionable and relevant, helping teams prioritize their responses more effectively.

The other methods, while useful in their own right, do not offer the same level of granularity and control over notifications as alerting profiles with filtering rules. For instance, tagging based on severity can categorize issues but does not dictate when notifications should be sent. Global settings adjustments apply to all alerts universally, which may lead to unwanted alerts or missed critical notifications. Context propagation settings are more concerned with the flow of information across services rather than the control of notification mechanisms.
