No, I don't need two agents, just asking in case of the OpenTelemetry Java agent, what is the better solution? 1. Use an OpenTelemetry agent for direct connection to SkyWalking with the protocol : a. -Dotel.exporter.otlp.protocol=http/protobuf b. -Dotel.exporter.otlp.protocol=grpc 2. Use an OpenTelemetry agent to send data to OpenTelemetry collector and try to export it to Skywalking AOP
