skywalking+opentelemetry,How to configure export Trace Data?

[zhangjiabin1010]

I try to collect trace data using OpentElemetry'S OLTP and export the trace data to SkyWalking's OAP Server. My otel-collector config is as follows:

`receivers:
otlp:
protocols:
grpc:
http:

exporters:
logging:
loglevel: debug

opencensus:
endpoint: 127.0.0.1:11800
insecure: true

jaeger:
endpoint: 127.0.0.1:14250
insecure: true

processors:
batch:
service:
pipelines:
traces:
receivers: [otlp]
exporters: [jaeger, logging, opencensus]
processors: [batch]`

But there is an error in my otel-collector：
Sender failed {"component_kind": "processor", "component_type": "batch", "component_name": "batch", "error": "EOF".
Get some help. Thank you

In addition, it is normal for me to use SkyWalking's agent to collect data and send it to OAP Server.

I think Skywalking OpenTelemetry receiver is used to receive metrics, not traces.
see https://skywalking.apache.org/docs/main/latest/en/setup/backend/backend-receivers/#opentelemetry-receiver

Hi ，body:

My situation:
Previously, we used skywalking-agent to transport trace data to skywalking-server. Now I continue to used the skywalking-agent and send the tracing data to otel-collector
, and then otel-collector forwards it to jaeger for storage and display.
The problem is that the tracing data cannot be passed to otel-collector.

My configuration:
/otel-collector/

/skywalking-agent config/
[root@cx-gateway-service-4100-6b6bdd45cc-pvj98 /]# env|grep SW
SW_LOGGING_DIR=/var/log/cx-gateway-service
SW_AGENT_NAME=cx-gateway-service
SW_AGENT_COLLECTOR_BACKEND_SERVICES=10.100.220.63:11800 # IP 10.100.220.63 is one of otel-collector node address
SW_LOGGING_MAX_HISTORY_FILES=50

Software Version:
skywalking-agent： 8.0.1
otel-collector： 0.85.0

According to the official documentation, when OTEL interconnects with Skywalking, there are few configuration steps. I don't know what steps I'm missing ？ Expect help from experts ，Thanks

Simple answer, we don't support that.

Our agents require our backend. You can't do things. We did more complex things compared with otel tracing.
