What does the `is_reliable` setting ensure when configuring the agent for dual shipping?

The is_reliable setting in the context of configuring the Datadog agent for dual shipping primarily focuses on ensuring that data is not missed if a destination becomes unavailable. This is critical for maintaining data integrity and availability, especially in scenarios where data needs to be sent to multiple endpoints or services. When this setting is enabled, the agent will make certain that it retains the data until it can successfully send it to the specified destination, effectively providing a buffer against potential data loss during transient issues.

This setting is particularly important for maintaining the reliability of systems that require continuous monitoring and alerting. By ensuring that no data is lost during times when a destination may not be reachable, organizations can trust that their observability data is complete and accurate, which is vital for effective incident response and operational insights.

In contrast, the other options address different aspects of performance or security. For example, while quick responses and consistent data sending are beneficial, they do not capture the essence of what is_reliable specifically provides. Similarly, data security, while important, is not the primary focus of the is_reliable setting in this context.
