What is one scenario for OpenTelemetry metric ingestion?

In the context of OpenTelemetry metric ingestion, sending metrics directly to OneAgent if on the same host is a relevant scenario because OneAgent acts as a collector that can receive telemetry data, including metrics, from applications running locally. This direct communication can streamline the process of obtaining performance metrics without introducing additional latency or complexity that might come from routing metrics through external services or additional tooling.

When applications and OneAgent share the same host, it simplifies configuration and can enhance the performance of metrics ingestion, as there is no need for network communication beyond the local loopback. This method allows for quicker response times and immediate access to real-time data, which is critical for performance monitoring and troubleshooting.

Other choices, while related to the general idea of metrics transmission and storage, do not align as closely with the typical usage patterns and capabilities associated with OpenTelemetry and OneAgent. For example, sending metrics via email is not a typical method for telemetry data conveyance due to issues like reliability and scalability. Exporting metrics to other cloud services involves more complex configurations and potentially additional overhead. Storing metrics in a local database is more about long-term storage rather than real-time ingestion and monitoring, which is the primary focus of OpenTelemetry's capabilities.
