描述

Use Case

Telegraf open telemetry plugin assumes gRPC input. However there are applications (example: pulp) that log open telemetry using http protobuf port 4318)

Changing the service address to use port to 4318 in the current collector does not change its behavior of expecting gRPC data.

Please add support for http protobuf (already present on the http input plugin) to the otel input

Expected behavior

When listening on service address with port 4318 the otel input should accept and parse http protobuf POST data

Actual behavior

When listening on service address with port 4318 the otel input still expects gRPC input data

研究方向
Investigate the existing OpenTelemetry input plugin in plugins/inputs/opentelemetry/ and the HTTP input plugin in plugins/inputs/http/. The goal is to add HTTP protobuf support to the OTEL input, similar to how the HTTP input handles protobuf. Review the gRPC vs HTTP protobuf differences in OpenTelemetry specification. The issue does not have linked PRs or assignees; ensure the implementation aligns with maintainer expectations by checking comments for any additional guidance.
