Good Evening, I need to export the data in json format from the collector...it has to be exported to http end point. Here is my configuration: otlp/http: endpoint: http://example.com/deeptrace But it is expecting the port number: Exporting failed. Will retry the request after interval. {"kind": "exporter", "name": "otlp/http", "error": "rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing dial tcp: address example.com/deeptrace: missing port in address\"", "interval": "3.358221818s"} Please let me know how to export the data in Json format.

The endpoint needs to be somethnig like this https://example.com:4318 for HTTP

Able to export the data to the below custom path..but data is reaching the target as follows. How to handle this ? Is the data coming like this becoz of custom path ? example.com/deeptrace Key -> None, Value -> b'{"ngo_log_type":"30","received_time":"2022-07-19T150336+0530","message":"\\n\xef\xbf\xbd\\u000F\\n\xef\xbf\xbd\\u0002\\n\\"\\n\\u0016telemetry.sdk.language\\u0012\\b\\n\\u0006python\\n%\\n\\u0012telemetry.sdk.name\\u0012\\u000F\\n\\ropentelemetry\\n!\\n\\u0015telemetry.sdk.version\\u0012\\b\\n\\u00061.10.0\\n\\u001E\\n\\fservice.name\\u0012\\u000E\\n\\fNGINXtestAPI\\n\\u001C\\n\\u0010application.name\\u0012\\b\\n\\u0006pocOTL\\n\\u0019\\n\\u0010environment.name\\u0012\\u0005\\n\\u0003Dev\\n\\u0017\\n\\btoken.id\\u0012\\u000B\\n\\ttoken2100\\n\\"\\n\\u0016telemetry.auto.version\\u0012\\b\\n\\u00060.29b0\\u0012\xef\xbf\xbd\\r\\n,\\n\\"opentelemetry.instrumentation.asgi\\u0012\\u00060.29b0\\u0012\xef\xbf\xbd\\u0001\\n\\u0010\xef\xbf\xbd_\xef\xbf\xbd\\u000B\xef\xbf\xbd6\xef\xbf\xbd\\u0018Q\xcf\x97/l\'\xef\xbf\xbd\xef\xbf\xbd\\u0012\\b\xef\xbf\xbdY\xef\xbf\xbd\xef\xbf\xbd\\u0014\xef\xbf\xbd|\xef\xbf\xbd\\"\\bV\xef\xbf\xbdQ\\u0016\xef\xbf\xbd8\\u001F\xef\xbf\xbd*\\u001A/items/{item_id} http Data before export: Resource SchemaURL: Resource labels: telemetry.sdk.language: STRING(python) telemetry.sdk.name: STRING(opentelemetry) telemetry.sdk.version: STRING(1.10.0) service.name: STRING(NGINXtestAPI) application.name: STRING(pocOTL) environment.name: STRING(Dev) token.id: STRING(token2100) telemetry.auto.version: STRING(0.29b0) InstrumentationLibrarySpans #0 InstrumentationLibraryMetrics SchemaURL: InstrumentationLibrary opentelemetry.instrumentation.asgi 0.29b0 Span #0 Trace ID : 0a9f0ac030b0f2ec630798f7514224f7 Parent ID : 148b60d17ad47fb0 ID : 2ef16279086619f1 Name : /items/{item_id} http send Kind : SPAN_KIND_INTERNAL Start time : 2022-07-19 063834.42840192 +0000 UTC End time : 2022-07-19 063834.429474048 +0000 UTC Status code : STATUS_CODE_UNSET Status message : Attributes: http.status_code: INT(200) type: STRING(http.response.start)

It's binary encoded protobuf. You are not using the json encoding.

How to export it as text format protobuf ?

You would use protobuf lib to deser the received data https://pkg.go.dev/google.golang.org/protobuf@v1.28.0/encoding/prototext. And this might be helpful too https://github.com/open-telemetry/opentelemetry-proto-go

THanks Srikanth! Instead of converting it like this, can I export it as text format protobuf from the collector ?

I am not sure what do you mean by that. The telemetry data is either binary or json encoded protobuf. You receiver has to deser it work with it.

ok. Let me check json export
